In my old 6h workshop (before Spring Framework 5 introduced reactive support, Spring Boot 2.0 and Spring Cloud Finchley) i would cover:

• REST (servlet)
• data access (JPA + H2)
• observability w/ actuator
• service registration & discovery
• client side load balancing w/ Eureka
• reliability patterns w/ circuit breakers
• eventual consistency / messaging w/ Spring Cloud Stream and RabbitMQ
• REST clients w/ RestTemplate abd Feign
• distributed tracing w/ Sleuth Stream + ZIpkin Stream Server
• Circuit Breaker dashboard (w/ no turbine)
• SSO w/ Spring Cloud Security
• microservice testing w/ Spring Cloud Contract
• Java
• edge services /microproxies/api gateways w Zuul

Now, in 2018, everything is bigger and better!

in my new 6h workshop (after reactive and Finchley) i will cover:

• REST (reactive w/ WebFlux)
• data access (reactive w/ MongoDB or R2DBC)
• observability w/ actuator (still works, but its micrometer)
• service registration & discovery w/ Consul
• client side load balancing w/ Consul
• reliability patterns w/ circuit breakers (works but now im using HystrixCommands and adapting a Publisher<T>)
• eventual consistency / messaging w/ Spring Cloud Stream and Kakfa
• REST clients w/ WebClient (Feign doesnt work; any alternatives? Does the stuff from Square work yet?)
• distributed tracing w/ Zipkin client and Kafka
• Circuit Breaker dashboard (w/ Turbine - havent tried this yet)
• SSO w/ Spring Cloud Security (whts this look like w/ Spring Security 5 and OIDC support)
• microservice testing w/ Spring Cloud Contract (i havent tries this yet in a reactive world)
• Kotlin
• edge services /microproxies/api gateways w Spring Cloud Gateay
• RSocket.io
