Remote backends change Terraform from a local workflow into a shared operational system.
This lesson explains why backend storage affects coordination, locking, authentication boundaries, and downstream infrastructure dependencies. The focus is not just backend syntax. The focus is what changes operationally when multiple operators share Terraform state.
The lesson walks through:
- Why remote state exists
- Why backend infrastructure must exist first
- How state locking prevents conflicting writes
- Why backend and provider credentials are separate
- How remote state outputs create dependencies
- What actually happens during backend migration
