Getting ready

Let's start our journey of understanding Azure serverless computing using Azure Functions by creating a basic backend Web API that responds to HTTP requests:

• Refer to https://azure.microsoft.com/en-in/free/?&wt.mc_id=AID607363_SEM_8y6Q27AS for creating a free Azure Account.
• Visit https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-function-app-portal to understand the step-by-step process of creating a function app, and https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-azure-function to create a function. While creating a function, a Storage Account is also created for storing all the files. Remember the name of the Storage Account, as it will be used later in other chapters.
• Once you have created the Function App, please go through the basic concepts of Triggers and Bindings, which are the core concepts of how Azure Functions work. I highly recommend that you to go through the https://docs.microsoft.com/en-us/azure/azure-functions/functions-triggers-bindings article before you proceed.
