A lot of what I see about platform engineering is based on a tech stack that includes Kubernetes and Terraform. I am interested in orgs that have implemented platform engineering in a fully (or near as possible) AWS native environment. I am talking mostly Lambda compute maybe some ECS or Beanstalk, CDK for IaC, Code* for CI/CD, etc. Is anyone here using such a stack or have you seen any good resources on building a platform engineering initiative on this stack?
