We need a consistent, self-documenting and version-controllable way of managing our infrastructure. So that anyone in our team or community can see exactly how everything is setup and we can evolve/improve our system without fear of "breaking" things in Production!
Setting up "Cloud" infrastructure for basic Apps using the Web UI is fine the first couple of times, in fact we encourage people to use the UI in order to learn how everythign works. Once you have a mission critical Application that many people rely on, setting things up manually by clicking UI is not sustainable.
Terraform enables you to safely and predictably create, change, and improve infrastructure. It is an open source tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.
