Summary

gRPC is a schema-driven framework developed by Google in 2015 to facilitate efficient service-to-service communication in distributed environments, using HTTP/2 and Protocol Buffers (Protobuf) for streaming and strongly typed service contracts. It was intended as an improvement over Google's previous RPC infrastructure and has since become part of the Cloud Native Computing Foundation. Unlike REST, gRPC allows for real-time, bidirectional data transfer, making it suitable for microservice architectures, streaming applications, and IoT systems. Despite its efficiency and language-agnostic nature, gRPC poses challenges such as the complexity of Protobuf, a steep learning curve, and a less mature ecosystem compared to older technologies. Tools like the Postman API Platform can aid in designing, developing, and debugging gRPC APIs by providing features like autocomplete hints, service definition creation, and gRPC server reflection.
