When we start a project, we usually have all the configurations in the properties file.
As more and more services are developed and deployed, adding and modifying these properties become more complex. Some services might go down, while some the location might change. This manual changing of properties may create issues.
Eureka Service Registration and Discovery helps in such scenarios. As all services are registered to the Eureka server and lookup done by calling the Eureka Server, any change in service locations need not be handled and is taken care of
This Post is divided into 4 parts-

• a.) Overview of Netflix components.
• b.) Develop an Employee service to produce and consume REST API using Spring Boot.
• c.) Use Eureka for Service Registration.
• d.) Use Eureka for Service Discovery.

Overview of Netflix components-

Spring Cloud Netflix provides Netflix OSS integrations for Spring Boot apps through autoconfiguration and binding to the Spring Environment and other Spring programming model idioms.
