I'm excited to see what sorts of CloudFormation templates people have lying around or which previously shared templates people find interesting.

To continue the show and tell part of Show HN, here are a few examples that caught my eye.

This example architecture that meets the Australian Cyber Security Centre’s Information Security Manual for the Protected classification level. It includes patterns you can borrow for three types of private subnets, AWS KMS-based encryption, and AWS WAF firewall protection. https://www.stackery.io/registry/?repo=https://github.com/aw...

Maybe you want to go back in time to 2019 when our problems involved how to construct serverless data lakes. If so, AWS Samples has you covered with this example which helps you think about both data ingestion and storage across several services. https://www.stackery.io/registry/?repo=https://github.com/aw...

I've seen a lot of shares of the serverlessland patterns library, including this deceptively simple pattern aka the "fan out" for managing data from kinesis streams. https://www.stackery.io/registry/?repo=https://github.com/aw...

Someone shared the DataDog template for deploying their integration, which you should scope the IAM Role to your resources before you deploy it, but it’s wonderful to see vendors providing CloudFormation templates for their stuff. https://www.stackery.io/registry/?repo=https://github.com/Da...

I see lots of shares from the consultancy Widdix. They focus on modular patterns that incorporate production-ready configurations, like this one for running container services in ECS. https://www.stackery.io/registry/?repo=https://github.com/wi...

Finally, if you’re feeling nostalgic for winter, this example from Symphonia is a lab for benchmarking Lambda cold starts for Java runtimes so that you can better understand how they behave and plan configurations accordingly. https://www.stackery.io/registry/?repo=https://github.com/sy...
