What Is Service Discovery?
When we talk about a microservices architecture, we refer to a system with a large number of small services, working with each other:
An important feature of such architectures is auto-scaling. The number of instances of a microservice varies based on the system load. Initially, you could have 5 instances of Microservice5, which go up later to 20, 100, or 1000!
