For example, if query A references a rule R, Trace Events emitted as part of Next posts, we will learn how to do the authorization check in the backend and front using the servers we created in this post. Lastly, I would like to share my thought on using OPA to do the authorization. It can be a boolean value or json. It is easier to control the rules since they are maintained in one place but this also creates a single point of failure and bottleneck which is not good in a distributed system. Typically new OPA language features will not require updating the service since neither the Wasm runtime nor the SDKs will be impacted. You can create policies or rules using its own language called Rego. Our mission is to provide unified authorization and policy across the cloud-native stack. Verify if the API server works by making a query to the server.
