NATS is an open-source messaging system aimed at high performance and availability. This session is all about NATS and NATS Streaming (a streaming server built on top of NATS). I will talk about the design philosophy behind NATS and why it differs from traditional message-brokers like for instance RabbitMQ. I will also walk you through the features it offers and finally I'll show you how to leverage NATS as the messaging infrastructure for event-driven systems. I do this by demonstrating this in a working microservices based .NET Core 3.0 application. Come to this session if you want to learn about NATS and NATS Streaming, when to use them (and when not to) and how to use them with .NET Core and C#.
