The Apigee Remote Service acts as a policy decision point (PDP) and advises Envoy to allow or deny access to the API consumer for the request. In general I would love to see this happen as I think this is a pretty big gap in the ecosystem right now. We currently have to run a separate gatekeeper proxy that handles the auth flow and having this feature would allow us to secure webapps from within envoy rather than within the webapp itself or by using a separate proxy. the HMAC validation. Envoy now allows extensions using WebAssembly (“WASM”) - a format for executing code written in multiple programming languages.
