A self-paced masterclass on defining and operating infrastructure as version-controlled code. It covers six stages: what infrastructure as code actually changes, state and the execution model, structuring code for real estates, testing and policy, the delivery pipeline, and operating it at scale including secrets, drift and disaster recovery.

The emphasis is on the things that bite in production — state, blast radius, drift and module design — rather than on syntax, so the material transfers between tools. Tech Skills Library is independent and issues no certification or credential.
