NATS is a Cloud Native messaging system designed to be lightweight and high-performance.
In this scenario, you'll learn how to start a NATS server and use it as a SUB/PUB message broker. The aim is to allow Microservices to communicate via NATS.
In this scenario we learned how to start the NATS Server, connect a client and use the protocol to SUB/PUB messages.
In future scenarios, we'll explore how to connect clients and use NATS Server within a Microservices architecture.
