Editor's Notes
- DevOps를 받쳐줄 도구가 필요함.
- Diving into Spring Cloud Netflix, for example, we see here some of the Netflix OSS projects for which Spring Cloud provides integrations. Ribbon, the Netflix client-side load balancer, and Eureka, the Netflix discovery server, can be used together as we saw earlier where the client side load balancer loads routing information from the discovery server and applies its own load balancing rules. Netflix Hystrix is an implementation of a circuit breaker. With Spring annotations, we can use AOP to add fallback commands to methods. We can also automatically report failures and metrics ass streams, in accordance with 12-factor app principles, and Netflix Turbine can collect these streams and provide an aggregated visualization into the state of all circuit breakers in the system. ------------------------------ Auxiliary notes: Ribbon: A client load balancer. Ribbon loads routing info from Eureka. It has several implementations of load balancing rules. Ribbon is used internally by Feign Feign: A declarative REST client. Allows annotation of interface to be mapped to endpoints. When combined with Ribbon it adds load balancing capabilities to the client interface Hystrix: Circuit breaker patter implementation. Via spring annotations add commands to methods using AOP. Protects clients from failures and reports metrics via a stream of HTTP events Zuul: A set of HTTP filters do add routing, security. On spring its used to create a CORS filter for UI apps to be able to access external services Archaius: Dynamic configuration management. Used with Spring’s config server to allow dynamic properties loading Eureka: Discovery server Turbine: Event aggregation engine. It can combine several streams (hystrix) into one combined view, that can be view later on a dashboard
