P4: Architecture Improvements

Our understanding of the Custos framework on a high level

What is Custos ?

Custos is a software framework that provides common security operations for science gateways, including user identity and access management, gateway tenant profile management, resource secrets management, and groups and sharing management

Architecture on a high level

• Custos is developed on a microservice architecture
• The microservices within the custos framework communicates through gRPC protocol
• The microservice's endpoints are exposed through the envoy side car which takes care of the conversion of the rest calls to gRPC messages
