Brief Concepts

What is Azure Serverless Architecture?

  • Accelerate your development with an event-driven, serverless compute experience.
  • Scale on demand and pay only for the resources you consume.


  • Manage your apps instead of infrastructure

    • Focus on building great apps.
    • Do not worry about provisioning and maintaining servers, especially when your workload grows.
    • Functions provide a fully-managed compute platform with high reliability and security.
    • With scale on demand, you get the resources you need—when you need them.

  • Develop your way

    • Create Functions in the language you choose, such as JavaScript, C#, and F#, and scripting options such as Python, PHP, Bash, Batch, and PowerShell.
    • Write code in an easy-to-use web-based interface or upload precompiled code built with your favorite development tool.
    • Take advantage of continuous deployment to integrate with your DevOps pipeline and use monitoring tools to troubleshoot.

  • Bind into services

    • Build rich, serverless scenarios by capitalizing on a range of Azure and external services.
    • Easily interact with Azure Cosmos DB, Storage and more and external services including Twilio, SendGrid, and others—by adding input/output bindings to Functions. Save costs with less code to maintain.


Implementation – Create a new Azure Logic App

Steps to be followed

  • Open Azure portal, click on Add and choose category “Web + Mobile”. Then, select an option of “Logic App”.
  • Fill-in the details and create a new resource group and click on “Create”.
  • Go the “All resources” section and see the newly created “Logic App” named as “logic-app-04-09-2017”.
  • Open the particular logic-app there and see the different options present.

Implementation – Access the new Logic App

Steps to be followed

  • In the opened section of the Cognitive Service, click on the Logic App Designer and see the multiple triggers and templates there.
  • Choose a trigger “When an HTTP request is received” and then click on "Save" to generate the URL.
  • Then, we can click on “Run” to activate the trigger and check the notification at the top for every HTTP request being hit by the “Run” action.
  • Once the operation is completed, we can see the output and input provided within the time taken to process the request.
