You can express this in Terraform, it's just a little more contrived. You release your changes as Terraform modules (a module in and of itself doesn't do anything, it's like a library/package), then your Terraform workspace instantiates both a "blue" module and a "green" module, at different versions, with DNS / load balancing resources depending on both modules and switching between either blue or green.
