What is OPA?
Open Policy Agent — CNCF policy engine for policy-as-code with Rego language. Practical definition for cloud-native security, platform engineering, and production architecture decisions.
Why It Matters
OPA appears in production engineering decisions around security, identity, reliability, and platform operations. Understanding the term helps you read architecture diagrams, debug incidents, and choose safer defaults.
When you see OPA in a course, article, architecture review, or incident write-up, connect it to the system boundary it protects, the team that owns it, and the failure mode it is meant to reduce.
