Azure Functions vs Web Jobs vs Logic Apps.

Azure Functions:

Azure Functions is the serverless computing service hosted on the Microsoft Azure public cloud. Azure Functions, and serverless computing, in general, is designed to accelerate and simplify application development.

Azure Functions cane be used to achieve decoupling, reusability and shared. It is also used for productions environment.

Uses:

• The Azure Event Hub can deliver different events that trigger functions related to conditions in the cloud environment or a user account.

• A generic web hook can process HTTP requests, which allows triggers to come from websites or GitHub repositories.

• Message traffic can trigger functions. For example, messages that arrive in an Azure Storage queue can trigger functions.

• Timers can also trigger Functions, which allows users to execute regular tasks, such as file cleanups, on a regular schedule.

Web Jobs:

This is the feature of the Azure App Service that enables you to run program or script in the same instance as a web API app or mobile app. It sis a Cloud service to run background tasks.

Below are some of the files types that supports Web Jobs for script or programs.

• .cmd, .bat, .exe (using Windows cmd)

• .ps1 (using PowerShell)

• .sh (using Bash)

• .php (using PHP)

• .py (using Python)

• .js (using Node.js)

• .jar (using Java)

Logic Apps:

Azure logic App is a cloud based platform to create and run automated workflows that integrate apps, data, Services and systems. These connector perform various actions in the workflow like logic Apps, durable azure functions.

Below are various types of triggers available for Azure Functions:

• Queue Trigger

• Timer Trigger

• Event Trigger

• Http Trigger

Deployment Azure Functions is a separate App Service Web Jobs run as a background service

that run in the App Service Plan for the App services like Web App,
