The number of vRealize Suite products in the management cluster increases as you add capabilities. A management cluster must contain a minimum set of products. You can expand the product set when you require additional capabilities.
Minimum Set of Management Cluster Products
The management cluster always includes a vCenter Server instance.
Extended Set of Products
As the complexity of the environment increases, you install and configure additional products. For example, vRealize Operations Manager and related products provide advanced monitoring features. vRealize Automation is the key element of your IaaS solution because it enables rapid modelling and provisioning of servers and desktops across virtual and physical, private and public, or hybrid cloud infrastructures. A vCenter Site Recovery Manager instance can provide replication to a secondary site for disaster recovery.
