+Service Discovery
+=================
+
+Service discovery is an architecture pattern used for components
+(micro-services) to locate each other. 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.

+‘Services’ Overview
+===================
+
+DCAE Services run on the DCAE platform. A service performs either
+monitors the virtualized network services or does analytics. A service
+is composed of one or more components, and performs a business need.
+
+Services are created in a ‘Service Design and Creation’ tool called
+‘Service Assurance Flow Designer’ by a Service Designer. This is done by
+\* 1. ‘compose’ing a service from the available SDC catalog components
+(actually from the TOSCA models representing the components), then \* 2.
+’submit’ing the service, which generates a Cloudify blueprint, is then
+automatically uploaded to INVENTORY, and then deployed by DEPLOYMENT
+HANDLER (once a DTI Event is triggered for the service). It should be
+noted that some service flows, specifally ’closed-loop’ flows, are not
+initiated by DTI, but are done by CLAMP.
