gRPC concepts ● Remote procedure calls gRPC framework allows a client to execute a “remote” (server-based) instruction as though it were part of the local system. ● Supported method types Unary, client streaming, server streaming, bidirectional streaming ● Protocol buffers (protobuf) Language-agnostic, platform-agnostic mechanism for encoding structured data ● .proto file Strongly-typed schema definition @getpostman

Protocol buffers gRPC uses Protocol Buffers for serializing structured data ● .proto file Defines the service interface and the message types that the service methods accept and return ● Services Defines gRPC services with RPC method parameters and return types specified as protocol buffer messages ● Messages Protocol buffer data is structured as messages, where each message is a small logical record of information containing a series of name-value pairs called fields. @getpostman
