• gRPC enables remote procedure calls to make them almost as simple to use as in process direct calls
• Microservice architecture is enabled by gRPC where a monolithic application is broken up into multiple microservices
• Service mesh comes up to automate or manage the microservices
• Proximal service mesh enhances gRPC to have the same traffic management and security functionality as the proxy
• The services in the mesh talk to each other directly without the proxies
