InfiniCache: Building a Distributed Cache on Top of AWS Lambda? — A review of an interesting paper called “InfiniCache: Exploiting Ephemeral Serverless Functions to Build a Cost-Effective Memory Cache” with a focus on the techniques used. As Mikhail says, “it takes courage and creativity to repurpose serverless stateless compute as a stateful memory store.”

'HTTP APIs' Now Generally Available on API Gateway — Amazon’s API Gateway has always supported HTTP, no? Well, yes, but the pattern was distinctly oriented around REST, whereas this new approach is more dynamic, cheaper, and offers latency reductions too. It can also be mixed with existing REST APIs if you so wish. And in case you missed it, last week Serverless Framework added support for HTTP APIs already.

The AWS Serverless Application Repository Adds Sharing for AWS Organizations — The AWS Serverless Application Repository (SAR) enables builders to package serverless applications and reuse them within their own AWS accounts or share more widely. Previously, SAR apps could only be shared with specific AWS account IDs or made publicly available, but now they can be shared with AWS Organizations specifically too.
