• Automation on installing and upgrading clusters; plus index maintenance can be achieved with zero downtime
• For continuous, incremental backups with point-in-time recovery
• Query optimization
• Index suggestions

A sample Ops Manager topology is as follows:

Aside from the Ops Manager and the MongoDB nodes, we also need snapshot storage if we have enabled backups.

Ops Manager can be a better alternative to Cloud Manager if we want an on-premises solution for security, or for other reasons. This is included as part of the MongoDB Enterprise Server paid solution.
