A real-time administration layer for policy engines like OPA and AWS Cedar, keeping authorization data and policies in sync across microservices.
OPAL (Open Policy Administration Layer) is an open-source administration layer for policy engines like Open Policy Agent (OPA) and AWS Cedar Agent. It solves the challenge of keeping policy agents synchronized with real-time changes in policy and authorization data from various sources such as databases, APIs, and third-party services, ensuring that access-control decisions are always based on the latest state.
Developers and platform engineers building microservices or cloud-native applications that require dynamic, fine-grained authorization, especially those using policy-as-code engines like OPA or Cedar in production environments.
Developers choose OPAL because it provides a scalable, real-time update mechanism for policy engines, eliminating manual synchronization efforts. Its cloud-native architecture and support for multiple policy engines make it a versatile solution for maintaining up-to-date authorization layers across distributed systems.
Policy and data administration, distribution, and real-time updates on top of Policy Agents (OPA, Cedar, ...)
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Detects changes from APIs, databases, Git, and SaaS services, pushing updates via a lightweight PubSub channel to ensure authorization layers are always current, as described in the key features.
Works with popular policy engines like OPA and AWS Cedar Agent, providing flexibility for different environments and policy languages, highlighted in the project description.
Uses a stateless client-server design that supports deployments of thousands of policy engines with high daily synchronization volumes, proven in production use cases.
Streamlines permissions in microservices by managing policy centrally while fetching data from distributed sources, enabling hybrid cloud security patterns as outlined in the use cases.
Setting up OPAL servers, clients, and PubSub channels requires integration with existing infrastructure, which can be complex and time-consuming for teams new to policy-as-code.
Primarily optimized for OPA and Cedar Agent; integrating with other policy engines may require custom development, lacking out-of-the-box support for niche or emerging systems.
Managing real-time updates and multiple data sources adds monitoring and maintenance burdens, increasing the risk of failures in distributed authorization layers.
