In this post, I’ll explain what Logical IDs are, how they’re generated, and why they’re important. Understanding this will help you avoid unexpected resource deletions and baffling “resource already exists” errors during deployment.

I did not attend in person, but that gave me time to consolidate this list of top new serverless features while everyone else is sleeping off the intense 5-day conference. And I envy them just a little.

I know because I built and productionized such solutions. It’s not complicated, but there are a few things to be aware of. I explain them in this in-depth tutorial, where we build a serverless ML pipeline.

That’s probably why the CDK, by default, uses AdministratorAccess Policy to deploy resources. But we can easily change it and increase the security of our AWS account, following the least privilege principle with a minimal additional burden.

I believe in Infrastructure as Code (IaC), but with the “code” being YAML. But after using CDK in real projects, the amount of heavy lifting it does and the vast reduction of a boilerplate code changed my view.
