Azure App Service

Nowadays, all organization needs to create fast web and mobile apps for any platform or device. Integrate your apps with SaaS solutions, connect with on-premises applications, and automate your business processes without the complexity of building and maintaining the technology infrastructure.

Microsoft Azure offers PaaS services where you can run your apps on fully managed virtual machines (VMs), with your choice of shared VM resources or dedicated VMs.

The Azure App Service includes web and mobile capabilities, new capabilities for automating business processes and hosting cloud APIs. As a single integrated service, App Service lets you compose various components — websites, mobile app backends, RESTful APIs, and business processes — into a single solution.

Azure Web Apps

App Service Web Apps is a fully managed to compute the platform that is optimized for hosting websites and web applications. This platform-as-a-service (PaaS) offering of Microsoft Azure lets you focus on your business logic while Azure takes care of the infrastructure to run and scale your apps.

Azure Web Apps enables you to build and host web applications in the programming language of your choice without managing infrastructure. It offers auto-scaling and high availability, supports both Windows and Linux, and enables automated deployments from GitHub, Visual Studio Team Services, or any Git repository.

The computing resources may be on shared or dedicated virtual machines (VMs), depending on the pricing tier that you choose. Your application code runs in a managed VM that is isolated from other customers.

Your code can be in any language or framework that is supported by Azure App Service, such as ASP.NET, Node.js, Java, PHP, or Python. You can also run scripts that use PowerShell and other scripting languages in a web app.

Several App Types

The Azure App Service offers several app types, each of which is intended to host a specific workload:

Application Type Purpose
Web Apps For hosting websites and web applications
Mobile Apps For hosting mobile app backends
API Apps For hosting RESTful APIs
Logic Apps For automating business processes and integrating systems and data across clouds without writing code

Creating a Service Plan

You can create an empty App Service plan from the App Service plan browse experience or as part of app creation.

App Service plans give you the flexibility to allocate specific apps to a given set of resources and further optimize your Azure resource utilization. This way, if you want to save money on your testing environment you can share a plan across multiple apps.

                                              Creating a New Empty Standard Service Plan

An App Service plan defines:

  • Region (West US, East US, etc.):
  • Scale count (one, two, three instances, etc.)
  • Instance size (Small, Medium, Large)
  • SKU (Free, Shared, Basic, Standard, Premium)

Your App Service plan can scale from Free and Shared SKUs to Basic, Standard, and Premium SKUs giving you access to more resources and features along the way. Also, you can move apps between plans if the plans are in the same resource group and geographical region.

You can scale an Azure App Service plan:

  • Changing the plan’s pricing tier
  • Changing the plan’s instance size
  • Changing the plan’s instance count

Deploy Web Apps

An app in Azure App Service can be associated with only one App Service plan at any given time.

Both apps and plans are contained in a resource group. A resource group serves as the life cycle boundary for every resource that’s within it. You can use it to manage all the pieces of an application together.

Because a single resource group can have multiple App Service plans, you can allocate different apps to different physical resources. You can separate resources from development, staging, and production environments, it lets you isolate resources.

When you deploy your web app, web app on Linux, mobile back end, and API app to App Service, you can deploy to a separate deployment slot instead of the default production slot when running in the Standard or Premium App Service plan mode. Deployment slots are live apps with their own hostnames. App content and configurations elements can be swapped between two deployment slots, including the production slot.

Creating a new Web App
                                                                                   Creating a New Web App

App deployment can leverage options that include continuous integration or local source control publishing, Web Deploy, and FTP. The recommended method for production app deployment is deployment slot swap. Deployment slots represent staging and integration environments associated with production apps. Deployment slots can be configured and targeted with web traffic for validation, and traffic can be swapped on demand for deployment to production with no downtime and automated warm-up. The steps of a deployment workflow can be easily automated via release management products such as Visual Studio Release Management.

Deploying web apps
                                                                      Adding a Deployment Slot

Deploying your app to App Service is a matter of deploying your code, binaries, content files, and their respective directory structure, to the /site/wwwroot directory in Azure (or the /site/wwwroot/App_Data/Jobs/ directory for WebJobs). App Service supports three different deployment processes:

  • Deploy by using Visual Studio
  • Deploy by using an FTP client
  • Deploy by Kudu (Git/Mercurial or OneDrive/Dropbox)

Running WebJobs

For automating tasks into your Web Apps you could use WebJobs.

Azure WebJobs provide an effortless way to run scripts or programs as background processes on App Service Web Apps. You can upload and run an executable file such as cmd, bat, exe (.NET), ps1, sh, php, py, js and jar. These programs run as WebJobs on a schedule (CRON) or continuously.

You can run programs or scripts in WebJobs in your Azure App Service web app in three ways: on demand, continuously, or on a schedule. There is no additional cost to use WebJobs.

By default, web apps are unloaded if they are idle for some period of time. This lets the system conserve resources. In the Basic or Standard mode, you can enable Always On to keep the app loaded all the time. If your app runs continuous WebJobs or runs WebJobs triggered using a CRON expression, you should enable Always On, or the web jobs may not run reliably.
