Introduction to Azure Web Apps

Azure App Service is a cloud service for hosting web applications, REST APIs, and mobile back ends. Developers can write code in their favorite language (e.g., .NET, Java, Node.js, PHP, Python, Ruby) and deploy it seamlessly using DevOps practices or by connecting to GitHub or Azure DevOps.

Azure Web Apps offers the following benefits:

  • High Availability and Scalability: Automatically scale your applications up or out based on demand.
  • Support for Multiple Languages: Deploy applications written in various popular programming languages.
  • Integrated DevOps: Seamless integration with CI/CD pipelines for automated deployments.
  • Global Distribution: Deploy your applications to data centers around the world.
  • Security: Built-in security features to protect your applications and data.
Get Started with Azure Web Apps

Getting Started

Deploying your first web application to Azure Web Apps is straightforward. You can use the Azure portal, Azure CLI, Visual Studio, or VS Code.

Using the Azure Portal

  1. Sign in to the Azure portal.
  2. Navigate to "App Services" and click "+ Create".
  3. Fill in the required details, including subscription, resource group, name, runtime stack, and region.
  4. Click "Review + create", then "Create".

Using Azure CLI

Create a resource group and an App Service plan:

az group create --name MyResourceGroup --location "East US"
az appservice plan create --name MyPlan --resource-group MyResourceGroup --sku F1

Create a Web App:

az webapp create --resource-group MyResourceGroup --plan MyPlan --name MyWebApp --deployment-local-git

Key Concepts

App Service Plan

An App Service plan defines a set of compute resources for your web app to run. The pricing tier of the plan determines the features, cost, and compute resources available.

Deployment Slots

Deployment slots allow you to manage deployments and perform phased rollouts. You can deploy a new version to a staging slot, test it, and then swap it with the production slot with zero downtime.

Custom Domains and SSL

You can map custom domain names to your web app and secure them with SSL certificates.

Monitoring and Diagnostics

Azure provides integrated monitoring tools to track the performance and health of your web applications.
