RPC is a new and modern framework for building scalable, modern, and fast APIs. It is leveraged by many top tech companies such as Google, Square, and Netflix and enables programmers to write microservices in any language they want while keeping the ability to easily communicate between these services. It relies on protocol buffers as the transport mechanism and the Service Definition Language. gRPC [Java] Master Class: Build Modern APIs and Microservices is the best way to get a great overview of all the possibilities offered by gRPC with your favourite language • Learn the gRPC theory to understand how gRPC works • Compare gRPC and the REST API paradigm • Write your gRPC service definitions in .proto files • Generate server and client code in Java using the Gradle gRPC plugin • Implement unary, server streaming, client streaming, and the bi-directional streaming API • Learn via exercises and solutions • Implement advanced concepts such as error handling, deadlines, and SSL security • Implement a full CRUD API on top of MongoDB • Get pointers to expand your learning journey and get inspired by real-world gRPC services All the code files are placed at https://github.com/PacktPublishing/gRPC-Java-Master-Class-Build-Modern-API-and-Microservices
