The DCAE platform uses [server-side discovery](http://microservices.io/patterns/server-side-discovery.html) and is using [Consul](https://www.consul.io/) as the service registry solution. + +## Service registration + +All components are required to register with Consul in order to be discovered. There are two methods of registration: self and 3rd party. The DCAE platform uses 3rd party registration which means components don't actually make the registration calls but defers that responsibility to a platform service. + +### Implementation for Docker + +[Registrator](http://gliderlabs.com/registrator/latest/) is an open source application that is responsible for registering all components that run as Docker containers. Registrator watches the local Docker engine's activity log and will register and unregister a Docker container when the container is started and stopped. + +### Implementation for CDAP + +The CDAP broker is a REST web service that is responsible for registering all components that run as CDAP applications. -- cgit 1.2.3-korg
