A service is an entity that an application developer works with to build stream apps. Examples of services include an Apache Storm cluster to which you want to deploy the stream application, a Kafka cluster that a stream application uses to create a streams, or an HBase cluster to which the stream application writes.

A service pool is a set of services associated with an Ambari managed cluster. You manage service pools by hovering your cursor over the Configuration tab and selecting Service Pool.

The Service Pool dashboard lists all existing service pools and enables you to create new and update existing service pools.
