DevOps Primer Part 1 – Adding an Azure Web App with a Swap deployment slot – Windows Management Experts (2023)

In this tutorial:

  • Create the Azure App services
  • Add an application to the deployment
  • Create a deployment slot for a staging application
  • Swap the application from staging to production

Note: You will need an active Azure Tenant or a Trial subscription to complete these tasks, however it is a quick read with snapshots to follow along.

Introduction

Azure App Serviceis a platform-as-a-service (PaaS) offering thatallows you to quickly build, deploy, and scale Web, API, Mobile, and Function apps. The App Service platform supports both Windows andLinux for running applications in a variety of languages and frameworks, such as.NET, .NET Core, Java, Ruby, Node.js, PHP, Python, and Docker containers.

App Service plans are containers for the apps that you deploy in App Service. App Service plans are offered in different tiers, withmore functionality provided by higher, more expensive tiers. The following list highlights some of the distinctions between the available tiers:

  • Free(Windows only):Run a small number of apps for free
  • Shared(Windows only): Run more apps and provides support for custom domains
  • Basic: Run unlimited apps and scale up to three instances with built-in load balancing
  • Standard: The first tier recommended for production workloads. It scales upto ten (10) instanceswith Autoscaling support and VNet integration to access resources in your Azure virtual networks without exposing them to the internet
  • Premium: Scale upto 20 instances and additional storage over the standard tier
  • Isolated: Scale upto 100 instances, runs inside of an Azure Virtual Network isolated from other customers, and supports private access use cases

The most up-to-date information for thefeatures included with each tier is available hereand in the Azure Portal as you will see in this Lab Step where you create an App Service plan.

Create the App Service Web App

Azure App Service Web Apps, or simply Web Apps, are the instances of your websites and web applications hosted in Azure App Service. For most scenarios, Web Apps is the best choice for hosting websites and web applications in Azure. Each Web App is deployed into an App Service plan. Web Apps are DevOps-ready and can be deployed using a variety of continuous deployment tools.

In this Lab Step, you will create a Windows-based Web App and learn about the other options available.

Navigate to ‘App Services’ in the console

Add A Deployment slot

Deployment slotsallow you to have separate instances of your application that have their own hostnames. This is useful for several reasons:

  • You can organize yourworkflow by having dedicated testing and staging slots in addition to the default production slot.
  • Once you have vetted a new release in the staging slot, you can swap it into production to avoid having to warm up the production application.
  • By swapping releases into production, the previousreleaseremains in a slot where it can easily be swapped back into production if an issue is found in the new release.

Each deployment slot maintains its own configuration and application settings.Deployment slots are available with the standard and premium App Service plans.

You will create one deployment slot tostage releases in this Lab Step.

Now that we have a staging version of the application to switch, we can add an application to manage

Key benefits of deployment slots are the ability to swap pre-warmed websites into production, and to easily roll back to the previous version,by repeating the last swap. It is a best practice to use deployment slots when deploying a Web App. There are different types of swaps that you can use depending on the level of confidence you have in a release:

(Video) Deploy, update, and test apps with no downtime using Azure App Service Deployment Slots

  • Auto Swap: As soon as an application is deployed to a slot it automatically swaps into a target slot. This is not the same as deploying directly to the target becausethe applicationgets a warm start, and the previous release of the target slot is preserved if a rollback is required.
  • Swap: The most basic swap type that requires you to manually trigger the swap operation.
  • Swap with preview: This type is similar to a regular swap but allows you to preview the swap before completing it.Because each slot maintains its own configuration andapplication settings, the web app may not behave exactly as it did in the originating slot, and that is a good thing.

Some settings such as SSL certificates, custom domain names, and scale settings do not swap when you swap deployment slots. Other settings do swap, such as monitoring and diagnostic settings, framework versions, app settings, and connection strings. However, app settings and connection strings can be configured to be sticky and stay with a slot. For example, if you have separatetest and production databases, you can configure the database connection string to stick toeach slot.

In this Lab, you will deploy a newrelease to staging and swap into production. You will use a pre-builtASP.NET Core 2app bundled in a Zip file thatis ready to deploy for simplicity.It is better to use a source-controlled deployment method in production. App Services supports deployments via GitHub, BitBucket, Visual Studio Team Services (VSTS), DropBox, and more. You will also see how app settings can be configured to stick to a slot.

Import Testing Application

  1. Download the pre-built applicationCALabApp.zip filethat you will deploy to the staging slot.
  2. In the staging app Slot >>Development tools>>Advanced tools
  3. Click the Go button to Launch Kudo
  4. Go to tools Zip Push Deploy

In this Lab Step, you deployed a Web App to production using Zip file deployment and a staging slot. It is a best practice to use deployment slot swaps to release Web Apps to production with zero downtime and pre-warming. You also saw how slot settings can be used to configure the behavior of Web Apps based on the slot that they occupy.

In the next Part II, we will go through Logging analytics to Monitor and Troubleshoot your application.
