This blog explores building scalable API Gateway integrations for microservices using VPC links. VPC links enable forwarding external traffic to backend microservices without exposing them to the internet or leaving the AWS network. The post covers scaling considerations based on using REST APIs versus HTTP APIs and how they integrate with NLBs or ALBs across VPCs.

Managing Lambda layers across multiple accounts and Regions can be challenging at scale. By using a combination of AWS Config, EventBridge Scheduler, AWS Systems Manager (SSM) Automation, and CloudFormation StackSets, it is possible to streamline the process.

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.

This post is written by Joaquin Rinaudo, Principal Security Consultant and Gezim Musliaj, DevOps Consultant. IBM MQ is a message-oriented middleware (MOM) product used by many enterprise organizations, including global banks, airlines, and healthcare and insurance companies. Customers often ask us for guidance on how they can integrate their existing on-premises MOM systems with new […]

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.
