Kasun Indrasiri - Author of "Microservices for the Enterprise"

Real-World microservices implementations often use a variety of communication protocols and standards to build different services. Although RESTful services were quite popular during the early stages of microservices, it is quite inefficient for most inter-microservice communication scenarios. gRPC has emerged as an efficient, reliable, and robust way to build inter-microservice communication owing to its rich service definition capabilities with protocol buffers, a variety of language support, and performance of being built on top of HTTP2.
In this session, we cover how different cloud native communication patterns can be implemented with gRPC. You can learn when and how to use gRPC Interceptors, Deadlines, Cancellation, Error Handling, Multiplexing, and Metadata [...]
