OPA exposes a set of APIs that enable unified, logically centralized policy management. Read this page if you are interested in how to build a control plane around OPA that enables policy distribution and collection of important telemetry data like decision logs.
OPA enables low-latency, highly-available policy enforcement by providing a lightweight engine for distributed architectures. By default, all of the policy and data that OPA uses to make decisions is kept in-memory:
OPA is designed to enable distributed policy enforcement. You can run OPA next to each and every service that needs to offload policy decision-making. By colocating OPA with the services that require decision-making, you ensure that policy decisions are rendered as fast as possible and in a highly-available manner.
To control and observe a set of OPAs, each OPA can be configured to connect to management APIs that enable:
- Policy distribution (Bundles)
- Decision telemetry (Decision Logs)
- Agent telemetry (Status)
- Dynamic agent configuration (Discovery)
By configuring and implementing these management APIs you can unify control and visibility over OPAs in your environments. OPA does not provide a control plane service out-of-the-box today.
