Open-sourcing cztack

We’re excited to announce the open source release of cztack (we pronounce it “stack”), a major tool in CZI’s infrastructure. cztack is a framework of Terraform modules that enables teams to build better, more robust cloud infrastructure with less pain. Along with fogg for managing Terraform infrastructure-as-code repositories, cztack provides a set of common building blocks that CZI engineers use to build infrastructure. To explain why this project exists, we’ll tell you a bit about how CZI works.
