Customize Amazon API Gateway destinations for execution logs

Amazon API Gateway execution logs help you trace request processing step by step through your REST API stages. They capture authorization results, integration latency, mapping template output, and error details that are otherwise invisible at the API surface. When a production request fails in a way the access log cannot explain, the execution log is […]

Bring your own client certificate for backend mTLS in Amazon API Gateway

Bring your own client certificate for backend mTLS in Amazon API Gateway

Enterprises that use Amazon API Gateway often want to bring their own client certificate for backend mutual TLS (mTLS) authentication. With API Gateway, you can now use a third-party or AWS Private CA-issued client certificate for the outbound mTLS handshake. In this post, you build a REST API with an outbound mTLS connection to an Amazon ECS backend.

Build high-performance apps with AWS Lambda Managed Instances

In this post, you will learn how to configure AWS Lambda Managed Instances by creating a Capacity Provider that defines your compute infrastructure, associating your Lambda function with that provider, and publishing a function version to provision the execution environments. We will conclude with production best practices including scaling strategies, thread safety, and observability for reliable performance.

More room to build: serverless services now support payloads up to 1 MB

To support cloud applications that increasingly depend on rich contextual data, AWS is raising the maximum payload size from 256 KB to 1 MB for asynchronous AWS Lambda function invocations, Amazon Amazon SQS, and Amazon EventBridge. Developers can use this enhancement to build and maintain context-rich event-driven systems and reduce the need for complex workarounds such as data chunking or external large object storage.

How potential performance upside with AWS Graviton helps reduce your costs further

Amazon Web Services (AWS) provides many mechanisms to optimize the price performance of workloads running on Amazon Elastic Compute Cloud (Amazon EC2), and the selection of the optimal infrastructure to run on can be one of the most impactful levers. When we started building the AWS Graviton processor, our goal was to optimize AWS Graviton […]

Enhancing API security with Amazon API Gateway TLS security policies

In this post, you will learn how the new Amazon API Gateway’s enhanced TLS security policies help you meet standards such as PCI DSS, Open Banking, and FIPS, while strengthening how your APIs handle TLS negotiation. This new capability increases your security posture without adding operational complexity, and provides you with a single, consistent way to standardize TLS configuration across your API Gateway infrastructure.
