HCP for cloud scale monitors service instances and automatically restarts them if they are not healthy.
For floating services, you can configure a pool of eligible HCP for cloud scale instances and the number of service instances that should be running at any time. You can also set the minimum and maximum number of instances running each service. If a service instance failure causes the number of service instances to go below the minimum, HCP for cloud scale starts another service instance on one of the HCP for cloud scale instances in the pool that doesn't already have that service instance running.
Persistent services run on the specific instances that you specify. If a persistent service fails, HCP for cloud scale restarts the service instance in the same HCP for cloud scale instance. HCP for cloud scale does not automatically bring up a new service instance on a different HCP for cloud scale instance.
