AWS API Gateway is a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. Lambda is function as a service(FAAS) product of AWS. The combination of these two services is amazing and it is slowly replacing the traditional backend. The combination is serverless, cost-efficient and infinitely scalable.
API Gateway has many integrations, but this post is all about the possible integrations between API Gateway and Lambda. The two possible integrations are Lambda-Proxy and Lambda. I had a tough time understanding them, so I am going to document their features, pros, cons and instructions to setup in a comprehensible way. If you know about them and just want to set it up, jump to the instructions part.
