In this article, you learned that it is possible to migrate a non-serverless web application to a serverless environment without changing much code. You learned about different tools that can help you in this process, like AWS Lambda Web Adapter and AWS Amplify, and how to solve common use cases, like migrating storage and authentication components.

After the application is hosted in a fully serverless environment, it can scale up and down to meet your needs. This web application is also performant once the backend is hosted in a Lambda function. If you need, from here you can start using the strangler pattern to refactor the application to take full advantage of the benefits of event-driven architecture.

To see all the steps of the migration, there is a playlist that contains all the tutorials for you to follow.
