Techorama Netherlands 2019

In this session, Steve will introduce gRPC, a modern high-performance RPC framework for inter-service communication. We'll look at how gRPC stacks up against existing REST-based communication and explore the benefits this technology has to offer. gRPC uses HTTP/2 as its transport protocol and ProtoBuf encoded content for efficient, fast communication. You'll see C# examples of how to build client and server gRPC components using ASP.NET Core 3.0, using the blazingly fast Kestrel web server. You'll learn how to define your proto3 service definition (contract) and integrate with MSBuild tooling to code gen the server and client components you'll need. You'll be amazed at how quickly a service can be created with little effort or boilerplate code required. You'll also see how additional clients can easily be generated for other languages such as Node.js to make connecting polyglot systems a breeze. It's a great time to begin taking notice of gRPC as a worthy contender to take over from REST for inter-service communication in microservice-based environments. It's time we started to let service talk their own language!
