Introduction to App Service in Azure

In this post would be explaining some term learned from working with app service that beginner would find useful when navigating or creating an app Service.

Platform as a Service

Platform as a Service is an Azure offering that helps you deploy application on the web without worrying about licensing, Windows or Linux version or Updating your Operating System. It helps you manage the underlying infrastructure and allows you to focus on deploying application.

Azure App Service

This is a Platform as a Service (PAAS) from azure that allows you to deploy your code on azure using GitHub or other Code hosting platform, it comes with a lot of pre built functions that makes deploying your app easy, examples are Authentication, API management, CI/CD etc.

Resource Group

Resource group is a logical container used to store resources like Storage, App Service, Virtual Network etc. on Azure.
Resource group allows you to manage all resources, manage Permission and Monitor Cost.

Zone Redundancy

To make your app available if there is a downtime in a particular location where your app has been deployed, you use Zone Redundancy, this is done when creating your app and it is used to deploy a copy of your app in 3 different azure zone, so that in case of a failure in a a zone another app instance continue to serve the application.

Deployment Slot

If you are trying to test changes you made you previously built or you want some changes to be available to some people who visit your web app, then deployment slot is what you need. It helps you preview changes made to your app, and also share this changes with some of your website visitors to get feedback on your app.
You do this by increase the traffic sent to the new slot created, the default number is 0 percent.
