Giriş
Sürüm isimlerinin açıklaması şöyle.

SpringCloud Abstraction Sağlar

Açıklaması şöyle

... Spring cloud just gives you abstractions over some set of tools (eureka, zuul, feign, ribbon etc.) making it easy for you to integrate with spring applications.

However, you can also achieve microservice architecture without using spring cloud. You can take advantage of tools like Kubernetes, docker swarm, haproxy, Kong, nginx etc to achieve the same. The advantage of not using spring cloud has its own pros and cons and vice versa.

Zuul - API Gateway

Zuul yazısına taşıdım.
