Get 'Go'ing with Microservices
summary
Builds a Go microservice that calculates unit price using protobufs and gRPC, generates Go clients/servers from .proto files, and serves on TCP port 20001 so BloomRPC can call calculateUnitPrice and return a fake value. Implements clients for cache, prices and fund services, uses Shopify decimal library, stubs those clients in tests, and exercises unit tests with stubs and a table-driven style. Code compiles, gRPC stubs work, and tests pass locally.
