  • S3 and Consul: For storage
  • Bash and Ruby: For scripting

It can be beneficial quite often - you are not forced to change your toolset; you can pretty much naturally integrate Terraform into your workflows without any big sacrifices. Introducing Terraform to an existing environment is easy. Pick one particular service you want to manage with it and write your first template. Decide on how...
