  Azure Architectural Component RegionPairs ⮚ Most Azure regions are paired with another region within the same geography (such as US, Europe, or Asia) at least 300 miles away ⮚ This approach allows for the replication of resources across a geography that helps reduce the likelihood of interruptions because of events such as natural disasters, civil unrest, power outages, or physical network outages that affect an entire region ⮚ For example, if a region in a pair was affected by a natural disaster, services would automatically fail over to the other region in its region pair.

  Azure subscriptions andManagement Groups Azure subscription ⮚ In Azure, subscriptions are a unit of management, billing, and scale. ⮚ Similar to how resource groups are a way to logically organize resources, subscriptions allow you to logically organize your resource groups and facilitate billing. ⮚ Using Azure requires an Azure subscription ⮚ An account can have multiple subscriptions There are two types of subscription boundaries that you can use ⮚ Billing boundary: This subscription type determines how an Azure account is billed for using Azure – E.g. Pay As You Go, CSP, Enterprise Agreement ⮚ Access control boundary: Azure applies access-management policies at the subscription level
• 4.
  Azure subscriptions andManagement Groups Azure Management Groups ⮚ Azure management groups provide a level of scope above subscriptions. You organize subscriptions into containers called management groups and apply governance conditions to the management groups. ⮚ All subscriptions within a management group automatically inherit the conditions applied to the management group ⮚ Management groups can be nested.
• 5.
  Azure resources andresource groups ⮚ A resource is the basic building block of Azure. Anything you create, provision, deploy, etc. is a resource. Virtual Machines (VMs), virtual networks, databases, cognitive services, etc. are all considered resources within Azure. ⮚ Resource groups are logical groupings of resources. When you create a resource, you’re required to place it into a resource group. ⮚ When you apply an action to a resource group, that action will apply to all the resources within the resource group. If you delete a resource group, all the resources will be deleted. If you grant or deny access to a resource group, you’ve granted or denied access to all the resources within the resource group.

  Azure Compute Services AzureVirtual Machines ⮚ With Azure Virtual Machines (VMs), you can create and use VMs in the cloud. ⮚ VMs provide infrastructure as a service (IaaS) in the form of a virtualized server and can be used in many ways. Just like a physical computer, you can customize all of the software running on your VM ⮚ An Azure VM gives you the flexibility of virtualization without having to buy and maintain the physical hardware that runs the VM ⮚ However, as an IaaS offering, you still need to configure, update, and maintain the software that runs on the VM

• 8.
  Azure Compute Services ScaleVMs in Azure You can run single VMs for testing, development, or minor tasks. Or you can group VMs together to provide high availability, scalability, and redundancy. Azure can also manage the grouping of VMs for you with features such as scale sets and availability sets. Virtual machine scale sets ⮚ Virtual machine scale sets let you create and manage a group of identical, load-balanced VMs ⮚ Scale sets allow you to centrally manage, configure, and update a large number of VMs in minutes ⮚ The number of VM instances can automatically increase or decrease in response to demand, or you can set it to scale based on a defined schedule ⮚ Virtual machine scale sets also automatically deploy a load balancer to make sure that your resources are being used efficiently. With virtual machine scale sets, you can build large-scale services for areas such as compute, big data, and container workloads.
• 9.
  Azure Compute Services Virtualmachine availability sets Availability sets are designed to ensure that VMs stagger updates and have varied power and network connectivity, preventing you from losing all your VMs with a single network or power failure. Availability sets groups VMs in two ways: update domain and fault domain. • Update domain: The update domain groups VMs that can be rebooted at the same time. This allows you to apply updates while knowing that only one update domain grouping will be offline at a time. All of the machines in one update domain will be updated. • Fault domain: The fault domain can be considered as a rack which has common power source and network switch. By default, an availability set will split your VMs across up to three fault domains. This helps protect against a physical power or networking failure by having VMs in different fault domains (thus being connected to different power and networking resources).

  Azure Compute Services AzureFunctions ⮚ Azure Functions is an event-driven, serverless compute option that doesn’t require maintaining virtual machines or containers. ⮚ If you build an app using VMs or containers, those resources have to be “running” in order for your app to function. With Azure Functions, an event wakes the function, alleviating the need to keep resources provisioned when there are no events. ⮚ Functions are commonly used when you need to perform work in response to an event (often via a REST request), timer, or message from another Azure service, and when that work can be completed quickly, within seconds or less. ⮚ Functions scale automatically based on demand. Azure Functions runs your code when it's triggered and automatically deallocates resources when the function is finished. In this model, you're only charged for the CPU time used while your function runs.
• 11.
  Azure Compute Services AzureContainers ⮚ A container is a unit of software that packages code and its dependencies, so the application runs quickly and reliably across computing environments ⮚ Much like running multiple virtual machines on a single physical host, you can run multiple containers on a single physical or virtual host. Unlike virtual machines, you don't manage the operating system for a container ⮚ Containers are lightweight and designed to be created, scaled out, and stopped dynamically. ⮚ One of the most popular container engines is Docker, which is supported by Azure. ⮚ Azure Container Instances offer the fastest and simplest way to run a container in Azure. Azure Container Instances are example of PaaS offering.

  Azure application hostingoptions Azure App Service ⮚ Azure App Service is an HTTP-based service for hosting web applications, REST APIs, and mobile back ends. It supports multiple languages, including .NET, .NET Core, Java, Ruby, Node.js, PHP, or Python ⮚ It offers automatic scaling and high availability. App Service supports Windows and Linux. It enables automated deployments from GitHub, Azure DevOps, or any Git repo to support a continuous deployment model. ⮚ The App Service is deployed on to an App Service Plan which would define the compute and Storage Capacity needed for the App Service

  Azure Networking Services AzureVirtual Networking(VNET) ⮚ Azure Virtual Network is the fundamental building block for your private network in Azure. A virtual network enables many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks ⮚ When you set up a virtual network, you define a private IP address space by using either public or private IP address ranges. The IP range only exists within the virtual network and isn't internet routable. You can divide that IP address space into subnets and allocate part of the defined address space to each named subnet ⮚ You can inter-connect multiple VNETs by using VNET peering or VNET to VNET connection using virtual network gateway device ⮚ You can connect to your on-premises networks privately using VPN Tunnels(site to site or point to site) or ExpressRoute ⮚ To control traffic flow, you may deploy Firewalls or use Network Security Groups
• 15.
  Azure Networking Services AzureExpress Route extends on-premises networks into Azure over a private connection that is facilitated by a connectivity provider.
• 16.
  Azure Networking Services AzureDNS ⮚ Azure DNS is a hosting service for DNS domains that provides name resolution by using Microsoft Azure infrastructure. ⮚ By hosting your domains in Azure, you can manage your DNS records using the same credentials, APIs, tools, and billing as your other Azure services. ⮚ Azure DNS also supports private DNS domains. This feature allows you to use your own custom domain names in your private virtual networks, rather than being stuck with the Azure-provided names.
