Accessing Amazon DynamoDB Using Amazon API Gateway Service Proxy
Description
An underutilized aspect of API Gateway is its ability to integrate directly with AWS services. It's common to see an API endpoint backed by an AWS Lambda function that performs the service API call, but with the API Gateway Service Proxy feature, developers are able to access services without this additional compute layer. This can reduce the overhead associated with function code development, as well as avoid limitations brought on by AWS Lambda cost, function concurrency, and cold starts.
In this lab, you will configure HTTP endpoints that interact directly with an Amazon DynamoDB table using an API Gateway Service Proxy.
