Part I: Introduction to Microsoft Azure

1. GETTING STARTED WITH AZURE

Introduction to Cloud Computing

The National Institute of Standards and Technology (NIST) defines cloud computing as the capability provided to the consumer to provision processing, storage, networks, and other fundamental computing resources. This allows the consumer to deploy and run arbitrary software, including operating systems and applications. At its core, cloud computing revolves around three main components: computing, storage, and networking.

Compute

Compute power in the cloud allows you to run algorithms, perform calculations, and operate your applications. One way to rent compute power is through virtual machines (VMs). These VMs are virtualized hardware similar to your laptop or desktop, hosted in the cloud provider's data center. The cloud provider installs the host operating system on physical hardware, accessible only to them. An abstraction layer called the Hypervisor virtualizes the physical hardware resources, presenting them to customers. This means that a VM is a representation of a portion of the physical hardware, which you can use to install any software needed for your applications.

Another way to rent compute power is through containers. Here, the cloud service provider manages the physical hardware and the host operating system, with a container engine running on top of the host OS. Containers provide a sandbox environment to install applications and their dependencies. Once the application and its dependencies are configured, it runs on the container engine. The third method for accessing compute power is using serverless runtimes. Serverless computing offers a lightweight option that still runs on the host operating system. It provides everything needed for the application, referred to as a "function," which is a piece of code executing business logic. Serverless is cost-efficient, as you only pay for the execution time of the code, unlike VMs and containers, which incur costs as long as they are running.

Storage

Cloud storage allows you to store various types of data, such as personal data, purchases, or images. There are several types of storage services available:

- Virtual Disk: Stores data from virtual machines.

- File Share: Enables multiple virtual machines to access the same data from a central location.

- Relational Database: Stores structured data, such as that from a shopping site.

- Document Database: A non-SQL database for flexible data structures.

- Blob Storage: Handles large amounts of unstructured data.

- Key/Value Storage: Stores data in a simple, fast-access format.

- Queue Storage: Manages message queuing for application workflows.

Networking

Cloud networking facilitates communication between clients, business clients, and applications running in the cloud. Key network services include:

- Virtual Network: Similar to a physical network, allowing the creation of a network in the cloud.

- Global Traffic Management: Directs clients to the nearest node for faster access.

- DNS: Resolves domain names to IP addresses.

- Firewall: Protects applications from unauthorized access.

- Load Balancer: Distributes traffic across multiple servers to ensure availability and reliability.

Cloud Deployment Models

Cloud deployment can be categorized into private, public, and hybrid clouds.

Private Cloud: This model runs data or applications on-premise. It supports legacy systems, offers complete control over infrastructure and security, and meets strict compliance requirements. However, it requires significant initial investment, limits agility, and demands IT expertise.

Public Cloud: Data or applications run on infrastructure managed by cloud vendors like Azure, AWS, or Google. It provides high scalability, agility, pay-as-you-go pricing, and reduces hardware and maintenance costs. However, it may not support all legacy systems, might not meet all compliance needs, and offers less control over hardware and services.

Hybrid Cloud: Combines on-premise and cloud infrastructure, supporting both legacy and modern applications. It offers flexibility, specific security, and compliance benefits, and leverages economies of scale. However, it requires initial investment and can be complex to set up and maintain.

Benefits of Cloud Computing

Cloud computing offers several advantages:

1. Cost-Effective: Pay for usage with no upfront costs, better cost predictions, and the ability to stop paying for unnecessary resources.

2. Scalable: Unlimited resources with options for vertical and horizontal scaling, both manually and automatically.

3. Elastic: Resources can be increased or decreased based on demand, accommodating peak and low seasons.

4. Up-to-Date: Access to the latest hardware and software without additional investment.

5. Reliable: Redundant data centers, fault-tolerant services, data backup, replication, and disaster recovery.

6. Global: Redundant data centers worldwide, closer to customers, meeting data residency and compliance laws.

7. Secure: Physical security, established policies and controls, experienced personnel, and a shared security model.

8. Economies of Scale: Efficiency, lower cost per unit, and savings on taxes and utilities.

Financial Models: CapEx vs. OpEx

CapEx (Capital Expenditure) involves upfront costs with value decreasing over time, including server, storage, network, backup, disaster recovery, and datacenter infrastructure costs. Benefits include fixed costs, budget-friendly planning, and ease of financial forecasting.

OpEx (Operational Expenditure) involves monthly expenses for consuming services or products, such as leasing cloud infrastructure, software, scaling resources, and per-user billing. Benefits include flexible spending, no large initial investments, and adapting costs based on usage.

Cloud Service Models

Cloud services are categorized into:

Infrastructure as a Service (IaaS): Provides control over operating systems and the rest of the stack, with the cloud vendor managing physical hardware and virtualization.

Platform as a Service (PaaS): The vendor manages everything except applications and data, allowing rapid development without managing infrastructure.

Software as a Service (SaaS): The vendor manages everything, and consumers simply use the software.

These models offer various levels of control and management, enabling businesses to choose the best fit for their needs.

Overview of Microsoft Azure

What is Azure?

Azure is Microsoft's cloud computing platform, providing tools to build, manage, and deploy applications on a global scale. Unlike Office365 or Microsoft 365, which are offered as Software as a Service (SaaS) to end-users, Azure is specifically targeted at developers and IT teams. Azure offers over 100 services, enabling users to accomplish a wide range of scenarios, from running legacy applications on virtual machines to developing advanced machine learning models and building bots with artificial intelligence.

Virtualization

To offer its cloud services, Azure leverages a technology known as virtualization, which sits above the hardware as part of the host operating system. Virtualization represents the underlying hardware as software. Here's how it works:

1. Physical Hardware: The actual server consists of physical components such as CPU, memory, disk drives, and network interfaces.

2. Host Operating System: An operating system, known as the host OS, is installed on this physical hardware.

3. Hypervisor: Modern operating systems feature a hypervisor, which represents the signals from the physical hardware as software equivalents used by virtual machines (VMs) that run on the host OS.

The hypervisor has several key functions:

- Resource Allocation: Ensures no VM consumes more resources than allocated.

- Data Isolation: Ensures data written to the physical disk or memory by one VM cannot be accessed by another.

- Programming Interfaces: Exposes APIs that allow software to control the hypervisor, such as creating new VMs with specific parameters.

Azure Behind the Scenes

Behind the scenes, Azure operates through a complex infrastructure within Microsoft data centers, comprising hundreds or thousands of racks filled with hardware servers. Each server runs the Windows Server operating system with hypervisor features enabled, allowing multiple VMs to run on each hardware server. Connectivity within the rack is provided by a network switch.

Fabric Controller: In each rack, one server runs a special software called a Fabric Controller. The Fabric Controller manages the servers within the rack and communicates with the hypervisor to create VMs, allocate storage, and configure networking. All Fabric Controllers in a data center are managed by a centralized software known as the Orchestrator.

Orchestrator: The Orchestrator manages resources across the entire data center, in contrast to the Fabric Controller, which is responsible for individual racks. The Orchestrator ensures efficient management and allocation of resources, maintaining the seamless operation of Azure's cloud services.

By understanding Azure, its underlying virtualization technology, and its operational mechanisms, you gain insight into how this powerful cloud platform supports a wide array of applications and services on a global scale.

2. AZURE ARCHITECTURE AND CORE CONCEPTS

Azure Regions and Availability Zones

Azure Regions and Availability Zones

Certain Azure services, such as Azure Active Directory, Azure Traffic Manager, and Azure DNS, are available globally and do not require selecting a specific region. However, it is important to note that there is a limit to the number of resources you can create within a region. If you reach this limit, you should either create a support ticket to extend the limit or create the resources in another region where the limit has not been reached.

Some regions are special and can be used for building applications that meet certain compliance or legal requirements. Access to these regions may be restricted if you do not need to meet those compliance requirements. For instance, the US Government and the Department of Defense regions are designed for US government agents and partners, operated by personnel with higher security clearance. The China regions are offered in partnership with third-party providers, and Microsoft does not maintain these data centers. The Germany region operates via a German data trustee model, with Deutsche Telekom's T-Systems International ensuring the data resides in Germany.

The Need for Multiple Data Centers

Azure requires many data centers across various regions for several reasons:

- Bringing your application and data closer to customers.

- Providing better scalability and redundancy.

- Ensuring data residency to help comply with user requirements.

Azure's Geographic Structure

Azure services are offered across four geographic areas:

1. Americas

2. Europe

3. Middle East and Africa

4. Asia Pacific

These geographies are subdivided to meet legal and compliance requirements, ensuring data residency and sovereignty within geographical boundaries. They are also designed to be fault-tolerant, capable of withstanding complete region failures. For example, GDPR laws require that data of European citizens remain on European soil.

Region Pairs

Each Azure region is paired with another region within the same geography, forming a Region Pair. This structure is beneficial for Business Continuity and Disaster Recovery (BCDR) plans. Region pairs must be directly connected and at least 300 miles apart to ensure workloads continue running in the event of a disaster. Some services offer automatic geo-redundant data replication using region pairs. Additionally, in the case of extensive Azure outages, one of the regions in the pair is prioritized to reduce downtime. Planned updates are rolled out to regions one at a time, and data continues to reside within the same geography even in case of disaster.

Examples of Region Pairs

- East US/West US

- North Europe/West Europe

- East Asia/Southeast Asia

- Exception: Brazil South/South Central US

Availability Zones

Availability Zones provide redundancy within a region. These are physically separate data centers within a region, connected through a private high-speed fiber optic network. Unlike region pairs, Availability Zones are in closer proximity and consist of multiple data centers, each equipped with its own power, cooling, and networking.

Benefits and Usage of Availability Zones

Availability Zones are crucial for core infrastructure services such as virtual machines, managed disks, IP addresses, load balancers, and SQL databases. If one zone goes down, the other continues to function. To architect your application for high availability, you can co-locate your compute, storage, networking, and data resources within a single Availability Zone and duplicate these resources in another zone. Be aware that duplicating resources across multiple zones may incur additional costs.

Resource Categories Supporting Availability Zones

There are two categories of resources that support Availability Zones:

1. VMs, managed disks, or IP addresses specified via Availability Zones at creation.

2. Storage or SQL database services automatically replicated across zones by the platform.

This brings us to the concept of Service Level Agreements (SLAs) which we will cover in the next lesson.

Resource Groups and Resource Management

Management Options in Azure

Microsoft Azure provides various options for managing Azure resources, catering to different user preferences and requirements. These options include web applications, mobile applications, command-line interfaces, and several SDKs for custom management functionalities.

Azure Portal

- This is where most novice users begin their journey with Azure.

- The Azure Portal is a web-based management interface accessible through any web browser, making it an ideal tool for learning about Azure.

- While great for beginners, the Azure Portal does not support task automation, which can make it time-consuming for repetitive tasks.

Azure PowerShell

- Azure PowerShell is a module that can be installed on Windows, Linux, or MacOS.

- This module adds additional cmdlets to PowerShell, enabling the management of Azure resources.

- Using Azure PowerShell, you can create administrative scripts and automate workflows, saving time compared to manual operations in the portal.

- PowerShell Core, which is cross-platform, does not come pre-installed, so you'll need to install it first, followed by the Azure PowerShell module.

- Installation reference.

Azure CLI

- Azure CLI is a cross-platform command-line tool for creating and managing Azure resources.

- It is Python-based and can run on any operating system with Python installed.

Azure Cloud Shell

- Azure Cloud Shell is a powerful command-line interface accessible from the Azure Portal via a web browser.

- Cloud Shell provides options for using either Azure CLI or PowerShell cmdlets.

- Besides the CLI, Cloud Shell includes various development tools such as Python, .NET, Node.js, Java, and Go.

- Cloud Shell is backed by an Azure file share drive where you can upload reference scripts or attach it to your local drive.

Azure Mobile App

- The Azure Mobile App allows you to manage Azure resources on the go.

- You can view the current status of resources, check important metrics, receive and review alerts.

- The app enables you to start, stop, restart, and connect to virtual machines, run scripts using Cloud Shell, and much more from your mobile device.

Software Development Kits and REST APIs

Azure also offers software development kits (SDKs) in various languages for implementing custom management functionality. If there is no SDK for your preferred language, you can use Azure's REST APIs to create the desired functionality yourself.

Since the Azure Portal is the easiest way to learn about Azure, we will delve into its features and functionalities in the next lesson.

Azure Resource Manager (ARM)

Resource: A manageable item available through Azure. Common resources include virtual machines, storage accounts, web apps, databases, and virtual networks, among others.

Resource Group: A container that holds related resources for an Azure solution. You can include all the resources for the solution or only those you want to manage as a group. Allocate resources to resource groups based on what makes the most sense for your organization. More details can be found in Resource groups.

Resource Provider: A service that supplies the resources you can deploy and manage through Resource Manager. Each provider offers operations for working with deployed resources. Common resource providers include Microsoft.Compute (virtual machines), Microsoft.Storage (storage accounts), and Microsoft.Web (web apps). More details can be found in Resource providers.

Resource Manager Template: A JSON file defining one or more resources to deploy to a resource group, including dependencies between resources. This template ensures consistent and repeatable resource deployment. More details can be found in Template deployment.

Declarative Syntax: This syntax lets you state what you intend to create without writing the sequence of programming commands to create it. Resource Manager templates are an example, where you define the properties for the infrastructure to deploy to Azure.

Guidance:

1. Define and deploy infrastructure through declarative syntax in Resource Manager templates, rather than through imperative commands.

2. Define all deployment and configuration steps in the template, avoiding manual setup steps.

3. Use imperative commands to manage resources, such as starting or stopping an app or machine.

4. Arrange resources with the same lifecycle in a resource group and use tags for organizing other resources.

Resource Groups

When defining your resource group, consider these factors:

1. Resources in a group should share the same lifecycle, meaning they are deployed, updated, and deleted together. If a resource like a database server has a different deployment cycle, place it in a different group.

2. Each resource can only exist in one resource group.

3. You can add or remove resources from a resource group at any time.

4. Resources can be moved between resource groups.

5. A resource group can contain resources from different regions.

6. Resource groups can be used to scope access control for administrative actions.

7. Resources in different groups can interact if they are related but do not share the same lifecycle.

Role-Based Access Control (RBAC)

RBAC allows you to segregate duties within your team, granting only the necessary access to perform their jobs. Instead of giving unrestricted permissions in your Azure subscription or resources, you can allow specific actions at a particular scope. Best practices include granting users the least privilege necessary to complete their work.

Resource Manager Templates

With Resource Manager, you can create templates (in JSON format) defining the infrastructure and configuration of your Azure solution. These templates enable consistent and repeatable deployments throughout the solution's lifecycle. When creating a solution from the portal, a deployment template is automatically included. You can customize this template to meet your specific needs, eliminating the need to create it from scratch.

Subscriptions and Billing

Introduction to AAD and Azure Billing

In this lesson, we will explore how Azure bills you for resources and how to restrict access to company resources.

Azure Billing

1. Each department within an enterprise can have its own subscription.

2. A bill is generated for each subscription on a monthly basis.

3. Charges appear 10 days after the billing period ends on the associated credit card.

4. Although each subscription is billed, the account owner is responsible for the payment.

5. For example, Marketing, Finance, and HR departments can have separate bills, aiding in budget tracking for each department.

6. This setup helps control individual department costs.

7. Different payment options, like separate credit cards, can be used for each subscription.

8. You can set a budget for each department and receive notifications if it is exceeded.

9. For better billing management, you can use the Cost Management and Billing service to understand and analyze costs in detail.

Azure Active Directory

Restricting access to resources and services is crucial for cloud security.

- Authentication in Azure is handled by Azure Active Directory (AAD).

- Azure Active Directory is a cloud-based identity provider supporting multiple authentication protocols, including modern standards like OpenID and OAuth.

- AAD allows you to register users, applications, create groups, and identities, functioning as a complete directory service.

- Tenants: Entities registered with AAD are partitioned into tenants, which are isolated instances managed by a single organization.

- Azure Active Directory is also used by other Microsoft cloud services like Office365, Microsoft Intune, and Dynamics365.

- When you sign up for any Microsoft service, an instance of AAD is automatically created for you.

- Note that there is no one-to-one relationship between your organization and AAD tenants.

- Each tenant can have multiple subscriptions, but each tenant has only one account. A subscription can be associated with a single tenant, and subscriptions can be transferred between tenants if needed.

Using AAD, you can manage access to every resource and subscription individually, providing flexibility to model your organization's access within Azure.

3. MANAGING AZURE RESOURCES

Azure Compute Concepts

Introduction to Azure Compute Concepts

In this lesson, we explore the fundamental compute services offered by Azure, each tailored to different application needs.

1. Virtual Machines

- Virtual Machines (VMs) provide a software emulation of a physical computer.

- They include virtual processors, memory, hard drives, and networking interfaces, requiring an installed operating system.

- Access to VMs is typically through Remote Desktop Connection (Windows) or SSH clients (Linux), simulating direct computer interaction.

- VMs offer extensive control, allowing installation of any application and legacy software.

2. Containers

- Containers operate similarly to VMs but do not necessitate their own operating system within each container.

- They package application dependencies and utilize the host OS kernel for execution.

- Multiple containers on a Linux server share the same kernel, limiting flexibility with OS diversity on a single server.

- For instance, Linux containers require a Linux host, while Windows containers require a Windows host.

3. App Service

- App Service is Azure's Platform-as-a-Service (PaaS) offering for hosting scalable web applications.

- It supports various runtimes like .NET, PHP, Node.js, and Java, enabling deployment of custom code.

- App Service abstracts underlying infrastructure management, providing control over runtime configurations for scalability, security, and compliance needs.

4. Serverless

- Serverless provides a cloud execution environment for custom code without managing underlying infrastructure.

- It operates based on triggers such as schedules, HTTP requests, or event-driven actions.

- Azure supports multiple languages (C#, JavaScript, Python, Java, PowerShell) for serverless applications, handling infrastructure management entirely.

Choosing Compute Services

Depending on application requirements, multiple Azure compute services may be chosen for different functionalities. For instance, deploying an online shopping website on App Service and using serverless functions for order processing.

Understanding each compute option's capabilities and constraints is crucial for effectively designing Azure applications. In upcoming lessons, we will delve deeper into each service to explore their specific features and best practices.

Creating and Managing Virtual Machines

Azure Virtual Machines

In this lesson, we will delve into the capabilities of Azure Virtual Machines (VMs). Azure VMs allow you to create virtual machines in the cloud, giving you complete control over the software running on them. You can install your preferred operating system and configure it to meet your specific requirements. You can also install and run custom software with minimal restrictions. VMs are managed by connecting remotely via an RDP client for Windows or an SSH client for Linux.

Provisioning a VM can be done in minutes using pre-configured images available from the Azure marketplace. These images are templates that include the operating system and other software such as hosting environments, web servers, databases, or complete applications. Additionally, you can create custom images from your on-premise environment and run them in Azure with ease, a process known as “lift-and-shift.” While running a single VM for development and testing is useful, Azure also offers advanced high-availability features for applications running on VMs, such as availability sets.

Availability Sets

An availability set is a logical grouping of two or more VMs that helps keep an application available during planned and unplanned maintenance. It uses fault domains and update domains to achieve this. When your VMs are in an availability set, Azure ensures they are placed across fault domains. Availability sets do not incur additional costs, but the number of VMs you run in Azure affects your overall costs.

Fault Domains

In Azure, a fault domain represents a single server rack with independent components such as power, cooling, network switch, and physical hardware. You can have up to three fault domains for your workloads. The more VMs you have per tier, the greater fault tolerance your application will achieve.

Update Domains

Update domains are important during planned maintenance when VMs need to be restarted. VMs are assigned to update domain groups using a proprietary algorithm, and users have no control over this process.

Scale Sets

Scale sets allow you to manage a group of identical servers, such as a web farm running Apache servers in parallel. The VMs in a scale set are placed behind a load balancer to distribute traffic evenly. If there is an increased workload, VMs can be added on-demand or on a predefined schedule. Azure Load Balancer has built-in integration with scale sets, automatically adding VMs to the load balancing pool. Once the load decreases, the load balancer stops traffic to the removed VMs.

Azure Batch

Azure Batch is a service that assists with large-scale job scheduling, capable of scaling to hundreds or thousands of VMs simultaneously for parallel calculations. It can be used for tasks such as encoding videos in different formats, rendering animations, or processing large datasets on a schedule. Azure Batch handles starting the VM pool, installing applications, staging data, running jobs, identifying failures, and scaling down when the work is complete. It supports both Windows and Linux OS for running jobs.

With this understanding of VM-based compute options in Azure, we will move on to discuss Azure Containers in the next lesson.

Azure Container Services

VM Downsides

While VMs and virtualized hardware are beneficial for migrating legacy applications to Azure, they have some disadvantages. For instance, if your application requires different runtime environments, you would need multiple VMs. For example, you might need NGINX for a web proxy, Node.js for business logic, Python for batch processing, and MongoDB as your database. Installing all components on one VM can lead to resource usage conflicts and compromise security. Additionally, tasks like starting and stopping VMs are slow, and the guest OS consumes CPU and memory, reducing overall efficiency.

Containers

Containers offer a solution for achieving isolation similar to VMs while increasing infrastructure efficiency. Multiple containers can run on the same host, sharing a single OS and avoiding the overhead of multiple VMs. Containers are lightweight, boot quickly, and can be created, scaled out, and stopped within seconds, allowing rapid response to demand changes. Containers virtualize the OS, dedicating more resources to the application and significantly improving infrastructure efficiency.

Microservices

Containers are closely associated with the microservices architecture trend. Microservices are small, well-defined services that are loosely coupled. Instead of building one monolithic application, you build many small services, each fulfilling a single business function. These services are then combined to provide the overall business logic of the application. Each service can be deployed as a set of containers configured to work together.

Benefits of Microservices

The microservices approach offers several benefits. Separate teams with specific expertise can develop microservices using different technologies, frameworks, and programming languages. This approach leverages team expertise and simplifies hiring. Microservices can be released and deployed independently, allowing for frequent updates. They require smaller codebases, making them easier to maintain and roll back in case of bugs. Additionally, microservices can be scaled independently, allowing targeted scaling of bottleneck services without affecting others.

Container Orchestration with Kubernetes

Managing containerized applications at scale requires container orchestration solutions like Kubernetes. A Kubernetes cluster consists of multiple nodes, each being a VM with a container engine, such as Docker, installed. Kubernetes manages the placement of pods (groups of containers) and dynamically adjusts them. If a pod fails, Kubernetes can restart it or redeploy it on another node. Kubernetes also handles scaling, staged deployments, persistent storage management, and networking. Kubernetes' APIs can automate deployment, management, and platform extension.

Azure supports Docker containers for Linux and Windows workloads.

Azure Container Services

Azure offers several services for running containers:

- ACI (Azure Container Instances): This service allows you to run a container without managing a VM or Docker engine. You simply upload and run your container.

- AKS (Azure Kubernetes Services): This is a comprehensive orchestration service for containers, capable of scaling to hundreds or thousands of nodes.

- ACR (Azure Container Registry): This service allows you to upload and version your container images. It is similar to Docker Hub and fully compliant with Docker container registry API. ACR enables you to create a private container repository and use approved container images within your application. You can configure ACI and AKS to pull images from ACR.

This overview covers the container technology services available in Azure. In the next lesson, we will explore the Platform-as-a-Service (PaaS) compute option, Azure App Service.

Working with Azure Storage

Data Types

Skills Learned From This Lesson: Data Types, Structure Data, Semi-Structured Data, Unstructured Data, Big Data

Before exploring storage options, it's important to understand the different types of data that enterprises collect.

Structured Data

Structured data is confined to a predefined schema and is stored in tables with rows and columns. Before storing data in a table, it is normalized to reduce redundancy, splitting the data into subsets and storing them in separate tables. These tables are linked using keys to indicate relationships, hence structured data is also known as relational data. Each column in a table stores specific data types such as integers, characters, strings, or dates, with the data types being enforced to ensure consistency.

Semi-Structured Data

Semi-structured data does not fit into tables or have a predetermined schema. Instead, it uses key-value pairs to organize data and provide a hierarchy. A typical example is JSON objects. Key-value data can be represented with two columns: a key column and a value column, with no limit on the amount of data stored in each column.

Unstructured Data

Unstructured data can be anything without any restriction on format or structure. It includes PDFs, Word documents, media files, pictures, or text files. Often, metadata is attached to unstructured data to provide some classification.

Big Data

Today, we generate a significant amount of data, from tweets and social media images to monitoring, analytical, security, and sensor data. By 2020, it was expected that each person would generate 1.7 MB of data per second. Gartner defines Big Data using three criteria: high volume, high velocity, and high variety. Big Data demands cost-effective, innovative processing methods that enable enhanced insight, decision-making, and process automation .

Azure Data Storage Options

Skills Learned From This Lesson: Azure SQL Database, Azure Cosmos DB, Azure Storage Blob, Azure File Share, Azure Disk Storage, Azure Data Lake Storage, Azure Queue Storage

Azure provides various data storage services suitable for different types of data. Let's look at these options in detail.

Azure SQL Database

Azure SQL Database is a relational database as a service (DaaS) based on the latest version of the Microsoft SQL Server database engine. It supports processing both relational and non-relational structures, including graphs, spatial data, JSON, and XML data. Advanced query processing features include intelligent query processing, advanced joins, interleaved execution, and high-performance in-memory technologies like in-memory OLTP and custom column store indexes. Azure SQL Database facilitates easy migration from on-premises SQL Server databases with minimal downtime using Azure Database Migration Services, making it ideal for structured data.

Azure Cosmos DB

Azure Cosmos DB is a globally distributed, schema-less database service that supports multiple APIs for access, including Cassandra, MongoDB, SQL, Gremlin, and Table APIs. This multi-model database offers global read-write capabilities and built-in Apache Spark support for real-time machine learning over globally distributed datasets. With a 99.999% SLA and multi-master support, it allows data writing from multiple locations, making it ideal for semi-structured data.

Azure Storage Blob

Azure Storage Blob is a highly scalable and unstructured storage solution for any kind of data. Accessible via HTTP/HTTPS endpoints globally, it features built-in geo-redundancy for disaster recovery and global access, ensuring strong consistency by verifying writes across all replicas. There are three types of Blobs: Block Blob, Page Blob, and Append Blob. This service is suitable for streaming applications like videos and audio or storing large amounts of data, such as monitoring and logging data. Azure Storage Blob offers different storage tiers—Hot, Cool, Archive, and Premium—to meet various application or business continuity needs.

Azure Data Lake Storage

Azure Data Lake Storage is an object storage solution dedicated to big data analytics. Built on Azure Storage Blob, it leverages low cost and tiered access while adding features like file system semantics and directory/file-level security. It supports both structured and unstructured data and offers Hadoop-compatible access for advanced analytics, forming the foundation for building enterprise data lakes for classifying and analyzing any type of data.

Azure Queue Storage

Azure Queue Storage is a simple, cost-effective, and durable messaging service that offers asynchronous messaging capabilities. It enables building flexible, loosely coupled applications that can scale independently. Accessible via HTTP/HTTPS endpoints globally, it allows multiple senders to send messages that can be processed by more than one receiver.

Azure Disk Storage

Azure Disk Storage provides disk storage for virtual machines (VMs), usable as primary boot disks for VMs with installed OS or for storing applications not accessible outside the VM. Azure offers various disk options, from startup spinning HDDs for infrequent data access needs to high-performance SSDs for demanding applications. Managed disks offer additional features like 99.999% SLA, integration with availability sets and zones, Azure backup support, and granular access control. Managed disks also support two types of encryption: Azure Disk Encryption (ADE) for OS and data disk encryption, and Azure Storage Service Encryption (SSE) for encrypting disks at rest.

Azure File Share

Azure File Share provides fully managed file shares via the Server Message Block (SMB) protocol. It can be mounted and accessed by any Windows, Linux, and Mac OS machine, either on-premise or in the cloud. Azure File Share allows sharing data between multiple VMs in Azure using high-performance file shares built on Azure Premium Storage tier, or extending on-premises file shares to the cloud with Azure File Sync.

Benefits of Cloud Data Storage

When comparing cloud data storage to on-premise options, several advantages become apparent.

Cloud Benefits

Azure offers a variety of storage types that can be leveraged to implement any type of application, including structured types like SQL Database, semi-structured types like Cosmos DB, and unstructured types like Storage Blobs. Implementing these options on-premise requires numerous servers and storage devices that need to be procured, configured, and maintained. This not only increases the time to market for your application but also the ongoing costs. With Azure, you can provision storage in minutes and start using it immediately in a cost-effective way, paying only for what you need. This allows better budget management and the ability to scale with your business needs. The on-demand nature of cloud storage services increases the agility of your development team, enabling them to adapt to changes and seize new opportunities without the delays associated with on-premise hardware procurement.

Azure Cloud Storage Tiers

Azure Cloud Storage offers different storage tiers to optimize costs and performance:

Hot Storage: Optimized for frequent access.

Cold Storage: Designed for data that is infrequently accessed and stored for at least 30 days.

Archive Storage: Suitable for data that is rarely accessed and stored for at least 180 days.

Benefits Continued

Implementing different storage tiers on-premise would at least double your infrastructure storage investment and significantly increase maintenance costs. Cloud storage, on the other hand, enhances the reliability of your application by providing automatic replication, backup, and restore capabilities across data centers and regions, which would require significant capital investment for on-premise solutions. Additionally, cloud storage incorporates built-in security features, including encryption during transfer, encryption at rest, and role-based access control, ensuring data security and compliance.

Azure Networking Essentials

Azure Virtual Networks

Skills Learned From This Lesson

Azure Virtual Networks, Subnets, Network Security Group, Routing Tables, Internet Gateway, VPN Gateway

Virtual Networks (VNET)

To understand how Azure segregates traffic for different customers, we need to learn about virtual networks (VNETs).

What is a Virtual Network (VNET)?

- Every machine in a local network is connected to a network switch, which manages the traffic and allows efficient communication between machines.

- If you have more than one customer on the network, you do not want the first customer to sniff the traffic of the second customer, and vice versa.

- Network switches can securely segregate traffic between virtual machines and isolate it, creating a Virtual Network.

- For instance, consider two virtual networks: one for blue servers and one for red servers.

- Cloud providers heavily use virtual networks to secure and isolate network traffic for different customers.

- Using a virtual network, your traffic is logically isolated from other customer networks, and you can configure it according to your needs without worrying about others listening in.

- A virtual network is your private network in the cloud, allowing you to create and deploy workloads.

Subnets

VNETs isolate your traffic from other customers in the cloud, but how do you isolate traffic within your own virtual network?

Designing a Network for a Three-Tier Application Environment

- A typical web application can consist of three logical tiers:

- Web Tier: e.g., Apache web application

- Application Tier: e.g., Tomcat for running your application

- Data Tier: e.g., SQL database server for storing data

- Each tier can consist of multiple virtual machines, all deployed in the same virtual network with a private address space (10.1.0.0/16).

- To secure access between tiers, segment your VNET into subnets, each with its own address range, a subset of the virtual network 10.1.0.0/16.

- You can protect each resource from undesired network traffic using an Azure Network Security Group (NSG).

Network Security Group (NSG)

- An NSG is a virtual firewall that allows or denies traffic to resources.

- You can configure an NSG for subnets and virtual machines in each tier.

- For example, create an NSG for the Data Tier to accept incoming traffic on port 3306 only, and an NSG for the Application Tier to accept incoming traffic on port 8080 only, while denying all outgoing traffic.

Internet and VPN Gateway

- If your Application Tier needs to make calls to an external web service via the internet, configure an Internet Gateway.

- If your Application Tier needs to communicate with your on-premise network, create a VPN Gateway that connects to your on-premise network.

- This way, an Azure VNET can become an extension of the on-premise network, enabling data transfer between on-premise and cloud environments, connecting to legacy applications, forming a Hybrid Cloud.

Routing Tables

- Routing Tables describe all possible routes for connectivity within Azure.

- Created per virtual network, Routing Tables are usually automatically updated when new resources like Internet Gateways or VPN Gateways are created.

- You can also create custom entries to override routes.

Azure Virtual Network

- You can create one or more virtual networks per region, scoped to a region, meaning you cannot create a virtual network that spans multiple regions.

- To communicate between two virtual networks, create a peering connection.

- For example, if you have Application servers in VNet #1 in Region 1 and VNet #3 in Region 2 that need to communicate with another Application server in VNet #2 in Region 1, establish peering connections between the VNets.

- Using VNets, you can deploy instances of your applications globally and establish peering connections to allow these instances to communicate and replicate data.

Now you know how virtual networks work and how Azure allows you to create your own VNet in the cloud and extend your on-premise network. In the next lesson, we will learn how you can extend your application using load balancers.

This decentralized model allows developers to work offline, commit changes locally, and synchronize with remote repositories when online.

Key Concepts of Git

- Repository: A Git repository, or repo, is a collection of files and folders associated with a project, along with the entire history of changes made to those files.

- Commit: A commit represents a snapshot of the repository at a specific point in time. Each commit records changes to files along with a commit message describing the modifications.

- Branch: Git uses branches to isolate workstreams and facilitate parallel development. Developers create branches from the main branch (often master or main) to implement new features or fixes without affecting the main codebase.

- Merge: Merging combines changes from one branch (source branch) into another (target branch), integrating new features or bug fixes into the main codebase.

- Pull Request: In collaborative workflows, a pull request (PR) is a mechanism for proposing changes to a repository. It allows team members to review, discuss, and validate code modifications before merging them into the main branch.

Benefits of Git

- Version Control: Git tracks changes at a granular level, providing a complete history of modifications. Developers can revert to previous versions, compare changes, and identify when and by whom specific changes were made.

- Collaboration: Git facilitates collaborative development by enabling multiple developers to work concurrently on different branches. Branching and merging capabilities streamline collaboration and reduce conflicts when integrating code changes.

- Workflow Flexibility: Git supports various workflows, such as feature branching, release management, and continuous integration/delivery (CI/CD). Teams can adopt workflows that align with their development practices and project requirements.

Practical Application

In practice, developers use Git through command-line interfaces (CLI) or graphical user interfaces (GUI) to manage repositories hosted on platforms like GitHub, GitLab, or Azure Repos.

Branching Strategies and Pull Requests

Branching strategies and pull requests are essential aspects of modern software development workflows, particularly when using version control systems like Git within Azure Repos or other platforms. These practices help teams manage code changes effectively, collaborate efficiently, and maintain codebase integrity throughout the development lifecycle.

Branching Strategies

A branching strategy defines how code changes are organized and integrated within a repository. Several common branching strategies include:

- Main/Branch (Trunk-Based Development): In this strategy, all development occurs on a single branch (often called main, master, or trunk). Developers work directly on this branch, committing changes frequently. This approach simplifies the workflow but requires robust automated testing and deployment practices to ensure code quality and stability.

- Feature Branching: Feature branching involves creating a dedicated branch for each new feature or task. Developers work on isolated branches, making changes and committing code without affecting the main branch. Once a feature is complete, it is merged back into the main branch through a pull request.

- Gitflow Workflow: Gitflow defines specific branches for different types of development activities:

- master: Represents stable, production-ready code.

- develop: Acts as the integration branch for ongoing development.

- Feature branches: Created from develop for new features.

- release and hotfix branches: Used for preparing releases and fixing critical issues.

Pull Requests

Pull requests (PRs) facilitate code review and collaboration in Git-based repositories. Here’s how they typically work:

1. Creating a Pull Request: When a developer completes work on a feature branch, they initiate a pull request to merge their changes into the target branch (often main or develop). The pull request includes details about the changes made, supporting documentation, and any associated tasks.

2. Code Review: Team members review the proposed changes within the pull request. They can provide feedback, suggest improvements, and discuss potential issues directly within the PR interface. Code reviews help ensure code quality, adherence to coding standards, and knowledge sharing among team members.

3. Continuous Integration (CI): As part of the pull request process, automated CI pipelines can run tests and validations on the proposed changes. CI pipelines check for build errors, run unit tests, perform static code analysis, and verify compliance with coding standards. This automated feedback loop ensures that changes integrate smoothly with the existing codebase.

4. Approval and Merge: Once the pull request passes code review and CI checks, it can be approved and merged into the target branch. Depending on the branching strategy, this merge may trigger further automated processes, such as deployment to staging or production environments.

Best Practices

- Small, Atomic Commits: Break down changes into small, focused commits that address specific tasks or features. This makes code reviews easier and simplifies the identification of bugs or regressions.

- Clear Documentation: Provide comprehensive descriptions, user stories, and acceptance criteria within pull requests. This helps reviewers understand the purpose of changes and their impact on the codebase.

- Automated Testing: Implement robust CI pipelines that automatically test code changes. This ensures consistent quality and reduces the risk of introducing errors into the main codebase.

- Iterative Improvement: Continuously refine branching strategies and pull request workflows based on team feedback and project requirements. Regularly evaluate and optimize processes to enhance productivity and codebase maintainability.

By adopting effective branching strategies and leveraging pull requests in Azure Repos or other Git repositories, development teams can foster collaboration, maintain code quality, and accelerate the delivery of reliable software solutions.

Part IV: Advanced Topics

10. ADVANCED NETWORKING IN AZURE

Configuring Network Security Groups (NSGs)

Configuring Network Security Groups (NSGs)

Network Security Groups (NSGs) are essential components in managing and securing network traffic in cloud environments, such as Microsoft Azure. They act as virtual firewalls, controlling inbound and outbound traffic to and from network interfaces (NICs), Virtual Machines (VMs), and subnets within your Virtual Network (VNet). Configuring NSGs properly is crucial for maintaining a robust security posture and ensuring that only authorized traffic is allowed while keeping malicious traffic at bay.

Understanding NSG Rules

NSGs operate based on a set of rules that define how traffic is filtered. Each rule specifies the source and destination, the protocol (TCP, UDP, or ICMP), the direction (inbound or outbound), and the action (allow or deny). Rules are processed in priority order, with lower numbers having higher priority. Default rules are provided, but custom rules can be created to meet specific security requirements. For example, you might allow HTTP traffic on port 80 from the internet to a web server, while denying all other inbound traffic.

Creating and Associating NSGs

To create an NSG in Azure, navigate to the Azure portal, select "Create a resource," and search for "Network Security Group." After creating the NSG, you can define the necessary security rules. Once your NSG is configured, it needs to be associated with a network interface, VM, or subnet. This association ensures that the NSG’s rules are applied to the traffic flowing through these resources. It’s advisable to associate NSGs at the subnet level for broader control or at the NIC level for more granular control.

Best Practices for NSG Configuration

Azure Functions is a serverless compute service provided by Microsoft Azure, allowing developers to build and deploy event-driven, scalable applications without managing infrastructure. Understanding Azure Functions is crucial for leveraging its capabilities to create efficient and responsive applications.

What are Azure Functions?

Azure Functions allows you to write small pieces of code, known as functions, that respond to events or triggers. These functions can be written in various programming languages such as C#, JavaScript, Python, and TypeScript, making it versatile for different development preferences. Functions are executed in a managed environment provided by Azure, where Azure takes care of scaling, patching, and infrastructure maintenance automatically.

Key Features and Concepts

Event-driven: Azure Functions are triggered by events from various sources, including HTTP requests, timers, message queues (like Azure Queue Storage), file uploads (Azure Blob Storage), and data changes in Azure services like Cosmos DB or Event Hubs. This event-driven model allows functions to respond to events in near real-time.

Bindings: Bindings are a powerful feature of Azure Functions that simplify integration with other Azure services. Bindings provide a declarative way to connect functions to input and output data sources without writing boilerplate code for connectivity. For example, an HTTP-triggered function can automatically bind to HTTP request data or output to a storage account without additional code.

Stateless Execution: Azure Functions are designed to be stateless by default, meaning each function execution is independent of previous executions. This architecture simplifies scaling and makes functions highly reliable. For scenarios requiring stateful workflows, Azure Durable Functions can be used to manage state and orchestrate long-running processes.

Use Cases for Azure Functions

Microservices: Azure Functions are ideal for building microservices architectures where each function performs a specific task or handles a specific event. This allows applications to be decomposed into smaller, independently deployable units, promoting scalability and agility.

Serverless APIs: Functions can be used to create lightweight APIs for processing HTTP requests. With Azure API Management integration, you can expose these APIs securely and manage them at scale.

Data Processing: Azure Functions are well-suited for processing data in real-time or batch jobs. For example, you can trigger functions to process new data uploaded to Azure Blob Storage or to analyze data streams from Azure Event Hubs.

Best Practices for Azure Functions Development

Granular Functions: Design functions to be small and focused on a single task or event. This promotes reusability, maintainability, and scalability.

Optimize Cold Start: Functions may experience a cold start delay when invoked infrequently. Design functions to handle cold starts gracefully by optimizing dependencies and minimizing startup time.

Monitor and Log: Use Azure Application Insights or other logging solutions to monitor function executions, track performance metrics, and diagnose issues. Implement logging within functions to capture relevant information for troubleshooting.

Security: Apply security best practices such as using managed identities for Azure services, securing sensitive information with Azure Key Vault, and implementing proper authentication and authorization mechanisms.

Practical Example
