  1. terraform

    Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

    A common architecture is to deploy substantially identical sets of resources across multiple regions for high availability. I've looked into this, and it seems that Terraform simply doesn't have a solution for multiregion deployments. Issue 24476 has a lengthy discussion about the technical details, but few practical suggestions for overcoming the limitations. There are a handful of posts on sites such as medium.com offering suggestions, but frankly many of these don't really solve the problems.
