Fellow SRE here, What are you doing my guy? Do you want the Devs to hate us more than they already do?

Let's go through things that totally unnecessary here. Terragrunt, Terraform Cloud (use S3 Bucket), API Gateway, CloudWatch, GitOps.

Blog Title should be "How to deploy Hello World Lambda Function, Enterprise style"

That is an incredibly complicated way of working. So many moving parts for the sake of moving parts.

Do you have a better way of managing lambda's with IaC? Usually Terraform or its derivative is the best way in my experience, especially if you don't really have an IaC ecosystem using something like Crossplane instead.

I don't get it, why not just use AWS CDK?

Can’t make a hackernews post by saying “write a normal standard lambda function with no customization whatsoever”

True. Sigh.
