Terraform feels like infrastructure management to me. We use it to provision underlying resources: Networking, Clusters, Nodes, Alerts, etc. All of the actual code deployments are entirely separate.
Ansible is more of a configuration management right?
Here's a comment from the author of ansible when terraform was first released: https://news.ycombinator.com/item?id=8100036
> One of the things shown in the Ansible examples are how to do a cloud deploy in one hop, i.e. request resources and also configure the stack all the way to the end, from one button press, and can also be used to orchestrate the rolling updates of those machines, working with the cloud load balancers and so on, throughout their entire life cycle -- all using just the one tool.
Edit: seems limited to ec2 and s3: https://docs.ansible.com/ansible/latest/collections/amazon/a...
Although you could provision other services with some custom modules using the aws-cli.
