“It’s time to migrate.”
Maybe the decision to switch cloud providers came “down from above.” Maybe the decision was yours. Perhaps your original solution was merely a spike to “kick the tires” of one cloud, and now it’s time to try another. Looking into a multi-cloud "hybrid" solution? Whatever your reasons, if you are considering moving your serverless code from AWS Lambda to Azure Functions, you’re in the right place to learn how!
“Moving from Lambda to Azure Functions” is a six-part videos series that covers what you need to know to make the transition between cloud providers. You’ll learn how to migrate your app, explore how resources in Azure relate to Amazon AWS, build a function locally, deploy it manually and learn how to push it automatically as part of a CI/CD pipeline.
The Sample App
The sample app is simple but does more than just echo text or print, “Hello, world.” It computes whether or not a number is a prime and uses a cache to store the results to serve them quickly on subsequent calls. The AWS Lambda implementation uses JavaScript (Node.js) and Amazon DynamoDB.
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
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.
To enable the cache, navigate to the storage account after it is created. Click on
TablesunderTable servicethen add a table namedprimes.
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…
The first video provides and overview of the sample application and shows how to test and access it from the portal and the command line.
In the next article, we'll explore how to create an Azure Function from scratch.
