HCP for cloud scale services

The following table describes the services that HCP for cloud scale runs. Each service runs within its own Docker container. For each service, the table lists:

Configuration settings: The settings you can configure for the service.
RAM needed per instance: The amount of RAM that, by default, the service needs on each instance on which it's deployed. For all services except for System services, this value is also the default Docker value of Container Memory for the service.
Number of instances: Shows both:
- The minimum number of instances on which a service must run to function properly.
- The best number of instances on which a service should run. If the system includes more than the minimum number of instances, you should take advantage of the instances by running services on them.
Service unit cost: For HCP for cloud scale, you can safely ignore these values.
Whether the service is stateful (that is, it saves data permanently to disk) or stateless (that is, it does not save data to disk).
Whether the service is persistent (that is, it must run on a specific instance) or supports floating (that is, it can run on any instance).
Whether the service is scalable or not.

Note: For HCP for cloud scale services, you cannot set the size of Max Heap Size larger than the value of the setting Container Memory. For other services, you should not set the size of Max Heap Size larger than the value of the setting Container Memory.
