This article is part of #ServerlessSeptember. You'll find other helpful articles, detailed tutorials, and videos in this all-things-Serverless content collection. New articles are published every day — that's right, every day — from community members and cloud advocates in the month of September.

Find out more about how Microsoft Azure enables your Serverless functions at https://docs.microsoft.com/azure/azure-functions/.

The previous episode in this series provided a high-level overview of serverless on Azure. This episode looks at cross-platform tools that enable you to build, run, and debug Azure Functions entirely from your local machine before easily deploying them to the cloud.

Build, Run, Debug and Deploy Azure Functions locally

This episode shows how to use the cross-platform Azure Functions core tools to create and run a local serverless project. Use the command or an editor like Visual Studio Code. See how to set a breakpoint, debug, and even modify local variables. Interact with storage using the cross-platform storage emulator. Finally, deploy your app to the cloud with just a few clicks.

Watch the episode here:

You can view the source code for the sample app and deploy the migrated code directly to Azure with a single-click in the “AWSMigration” GitHub repository.

Migrate from AWS Lambda to Azure Functions

Move AWS Lambda to Azure Functions

This is the source code for the "Moving from Lambda to Azure Functions" video series that demonstrates how to migrate from AWS Lambda to Azure Functions.

Quick Start

Free Azure Account Get your Free Azure Account

You can get started quickly with the migrated function. Simply click or tap the "Deploy to Azure" button. Be sure to enter a unique prefix (for example, use your initials or add a sequence). After the deployment is done, you can access and test the function.

Deploy to Azure

To enable the cache, navigate to the storage account after it is created. Click on Tables under Table service then add a table named primes.

The Code

This repository contains code for all related projects.

Source ("Pure") Function

The function itself determines whether a number passed is prime or not. The pure function is available in src\isItAPrime.js

In the next article, we'll look at advanced concepts like security, identity, and CI/CD.
