This is also more of the 'containerized'/Docker-like infrastructure development workflow.
Tools like Ansible and SaltStack also provide pretty robust infrastructure orchestration/management tools that are conveniently provider-agnostic. I save a ton of money by spreading out servers for one particular service over a bunch of lower-cost providers (rather than AWS), and use Ansible to manage them all.
If you play in one particular cloud infrastructure, image-based configuration and provisioning may work fine, but if you need to support the movement of images from developer workstations through to different hosting providers (whether using Docker, CM, or bash scripts), Ansible can help with that (as can Packer, Terraform, etc.).
