Simplify Complexity: GRPC Made Accessible
HTTP remains a preferred choice globally due to its well-developed ecosystem of load balancers, proxies, and caching systems. However, there is a demand for a more semantically simple solution that effectively connects internal and external systems, leading to the need for a 'protobuf flavored HTTP.' GRPC emerged as a bridging technology developed by a team at Google, primarily used for Google Cloud Platform but also available for open-source use. Despite its perceived complexity and the mystique surrounding it, GRPC's protocol is straightforward, defined easily in a few simple steps: utilize a protobuf schema to determine the path, set essential headers, and transmit protobuf bytes in the body. The implementation of GRPC is limited, with notable versions existing in Go and Java, yet creating a GRPC handler or client is not fundamentally more challenging than working with REST.
