Application-driven infrastructure: Stop pre-building environments, start deploying on demand

Kief Morris argues that pre-provisioned infrastructure—the common pattern of a central team building static environments—creates a paradox: teams either wait for environments or overspend on idle ones. This friction stems from treating infrastructure like physical hardware, despite the cloud's API-driven flexibility.

The alternative is application-driven infrastructure: provisioning and updating infrastructure as part of the application deployment process. This allows ephemeral, just-enough environments and decouples teams from central bottlenecks. The key enabler is composable infrastructure, breaking monolithic Terraform projects into smaller, independently deployable components.

This approach requires a shift in governance. Instead of a platform team building every environment, they build validated, reusable infrastructure components. Teams can then assemble what they need, using pipelines for compliance. The tradeoff is upfront investment in component design and orchestration, which most organizations underestimate.
