This blog post shows how to protect a Lambda Function URL, configured with IAM authentication, using a CloudFront distribution and Lambda@Edge. CloudFront helps protect from DDoS, and the function at the edge adds appropriate headers to the request to authenticate it for Lambda.

Reliable interservice communication is an important consideration in microservice design, especially when faced with dual writes. Combining the transactional outbox pattern with dual writes provides a robust way of improving message reliability.

Lambda response streaming can improve the TTFB for web pages. With the support of AWS Lambda Web Adapter, developers can more easily package web applications that support Lambda response streaming, enhancing the user experience and performance metrics of their web applications.

You can build and deploy functions using Python 3.11 using the AWS Management Console, AWS CLI, AWS SDK, AWS SAM, AWS CDK, or your choice of Infrastructure as Code (IaC). You can also use the Python 3.11 container base image if you prefer to build and deploy your functions using container images.

Lambda is deprecating the go1.x runtime in line with Amazon Linux 1 end-of-life, scheduled for December 31, 2023. Customers using Go with Lambda should migrate their functions to the provided.al2 runtime. Benefits include support for AWS Graviton2 processors with better price-performance, and a streamlined invoke path with faster performance.

When building event-driven applications, consider whether you can replace application code with serverless integration services to improve the resilience of your application and provide a clean separation between application logic and system dependencies.

This blog explains three key throttle limits applied on Lambda invokes: the concurrency limit, TPS limit and burst limit. It outlines the relationship between these limits and how each one protects the system and your workload from noisy neighbors. Equipped with this knowledge you can better interpret any 429 throttling exceptions you may receive while scaling your applications on Lambda.

Get started building with Ruby 3.2 today by making necessary changes for compatibility with Ruby 3.2, and specifying a runtime parameter value of ruby3.2 when creating or updating your Lambda functions.

This blog post demonstrates a solution that allows customers to utilize their private endpoints securely with API Gateway across AWS accounts and within a VPC network by using a reverse proxy with a custom domain name. The solution offers a simplified approach to manage the mapping between private endpoints with API Gateway and custom domain names, ensuring seamless connectivity and security.
