How to define Serverless APIs backed by AWS Lambda
Amazon API Gateway allows you to design RESTful interfaces and connect them with your favorite backend. You can design your own resources structure, add dynamic routing parameters and develop custom authorizations logic. Each API resource can be configured independently, while each stage can have specific cache, throttling and logging configurations.
This approach is particularly useful when you consider that each request and response can be attached to a custom mapping template, in order to perform custom data manipulation or improve API backward compatibility.
We will see how to define a simple API and how to connect it to AWS Lambda. Doing so provides a nice way to obtain a scalable backend for modern web applications or mobile apps. We will configure custom stages, protect resources with an API key and explain how to best connect API Gateway stages with AWS Lambda versions and aliases.
Lastly, we will learn about AWS Lambda's basic configuration, monitoring and versioning.
