Many technologies are available to implement service discovery pattern in the Microservices world. This includes Netflix Eureka, Kubernetes, Istio, Consul and many other frameworks. With this article, I am trying to develop the understanding of this pattern with the basic implementation of it. The article is divided in following sections —

• The need for Service Discovery
• Client-side Service Discovery
• Server-side Service Discovery
• Comparison and Next Steps

Microservices are dynamic in nature. This means multiple instances of a single Microservice will be co-existing. Most probably your instances will either have a different IP address or a different port or both. And the number of…
