Automating mutual TLS setup for Amazon API Gateway

Mutual TLS (mTLS) for API Gateway is now generally available at no additional cost. This post shows how to automate mutual TLS for Amazon API Gateway HTTP APIs using the AWS Certificate Manager Private Certificate Authority as a private CA. Using infrastructure as code (IaC) enables you to develop, deploy, and scale cloud applications, often with greater speed, less risk, and reduced cost.

Optimizing batch processing with custom checkpoints in AWS Lambda

The default behavior for stream processing in Lambda functions enables entire batches of messages to succeed or fail. You can also use batch bisecting functionality to retry batches iteratively if a single message fails. Now with custom checkpoints, you have more control over handling failed messages.
