Routing Rules for REST APIs 🚀☁️ #80
And AWS CDK Toolkit library goes GA
In the previous issue, Aurora DSQL goes GA 🚀☁️ #79, which celebrated the DSQL going DA and the new MCP for AWS Serverless and Containers.
Amazon API Gateway announces support for dynamic routing when you have custom domain names mapped to the API Gateway, allowing you to setup routing rules that give you the flexibility to define your conditions and actions as well as priority with the values from HTTP headers. This enables the development teams to define APIs for API versioning, A/B testing, and also makes the API spec easier to understand for the API consumers/developers.
Anton Aleksandrov and Giedrius Praspaliauskas also share about dynamically routing requests with API Gateway routing rules.
Welcoming the newest AWS Heroes - Christian Bonzelet, David Victoria, and Nora Schöner.
At AWS Summit Bengaluru 2025, a few of the Heroes - Bhuvaneswari , Vivek, Jones, and Ayyanar had a chat with Danish Sait, here is the complete video.
⭐ Pick of the month
This month’s Pick is “Event Driven Architecture (EDA)“.
Rajesh Kumar Pandey delves into sharing the design of resilient EDA systems at scale, where latency is not the primary challenge, but rather resilience and how failure retries, along with observability, are key considerations.
How to choose between EventBridge, SNS, and SQS for EDA patterns by Arpad Toth gives you a clear picture about the 3 EDA Services along with the patterns for fan-out or FIFO queues, along with considerations and cost comparison.
Jones Zachariah Noel N (Author) shares why observability matters for Event-Driven Architectures, bringing in challenges of EDA with AWS services and how metrics, specifically from SQS and SNS with New Relic integrations, help. And if you are still confused - What? Why? When? EDA
🚀 AWSome content to learn from
