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.

Benefits

• 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.

Prerequisites

• Read the following article to create an Azure account and for some basic information about Azure to get started.

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.
