  • Understand the Configuration techniques that Spring Boot Provides
  • Build Spring boot based Microservices for Json and XML data exchange
  • Monitor services using the Prometheus Actuator
  • Understand the major components of Netflix OSS
  • Register services with a Eureka Service
  • Implement “client” load balancing with Ribbon to Eureka managed Services
  • Create fault tolerant services with Hystrix callbacks
  • Filter requests to your Microservices using Zuul
  • Create producer and Consumer services using Kafka and Zookeeper
  • Define Feign clients to your services
