 There's a bunch of common patterns in distributed systems, which could help us to make described core services work. [Spring cloud](http://projects.spring.io/spring-cloud/) provides powerful tools that enhance Spring Boot applications behaviour to implement those patterns. I'll cover them briefly.

 ### Config service
-[Spring Cloud Config](http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html) provides horizontally scalable centralized configuration service in a distributed system. It uses a pluggable repository layer that currently supports local storage, Git, and Subversion.

 In this project, I use `native profile`, which simply loads config files from the local classpath. You can see `shared` directory in [Config service resources](https://github.com/sqshq/PiggyMetrics/tree/master/config/src/main/resources). Those config files are shared with all applications in cluster. For example, when Statistics-service requests it's configuration, Config service will response with `shared/statistics-service.yml` and `shared/application.yml` (which is shared between all client applications).
