This post is written by Alexander Schüren, Sr Specialist SA, Powertools. One of the design principles of AWS Lambda is to “develop for retries and failures”. If your function fails, the Lambda service will retry and invoke your function again with the same event payload. Therefore, when your function performs tasks such as processing orders […]

This post is written by Suranjan Choudhury (Head of TME and ITeS SA) and Anil Sharma (Sr PSA, Migration)  Chaos engineering is the process of stressing an application in testing or production environments by creating disruptive events, such as outages, observing how the system responds, and implementing improvements. Chaos engineering helps you create the real-world […]

Using Lambda extensions can open up a wide range of options to extend the capability of serverless architectures. This blog shows a Lambda extension that creates a secure VPN tunnel using the WireGuard protocol and the Tailscale service to proxy events through to an EC2 instance inaccessible from the internet.

In this blog post, you learn how you can securely share files with authorized external parties and track their access using AWS serverless services. The sample application presented uses Step Functions to allow you to extend and customize the workflows to meet your use case requirements.

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.
