So why not just use modules?

With terraform you’re in charge of one thing. And that’s by design.

• Write configuration

Terraform performs these high-level operations. You have no say in the matter.

• Read in configuration
• Do some transformations
• Build DAG
• Generate json
• Do things

Not necessarily a bad thing, but there are drawbacks.

1. A lot of code is still duplicated.
   • Throwing things up is still easy, but making a change in many little places is painful and error prone.
2. The module isn’t always the best abstraction layer.
