Managing Costs:
With its capacity and cost management features, vRealize Operations Cloud can predict future demand and provide actionable recommendations to help in managing costs.
Reclamation of Existing Resources:
Assess workload status and resource contention in data centers across your environment:
Determine the time remaining until CPU, memory, or storage resources run out.
Realize cost savings when underutilized VMs are identified and reclaimed to be deployed more effectively.
Future Infrastructure Requirements
Run what-if scenarios:
Identify how much capacity remains after you add or remove VMs or hosts.
Add hyperconverged infrastructure (HCI) nodes.
Get a recommendation based on the cost relative to workload placement on different hosts, clusters, data centers, and even different clouds.
Cloud Migration Planning:
Migration planning shows you the capacity and cost information after the migration to a cloud-based infrastructure.
Cost Overview
vRealize Operations Cloud supports costing for private clouds, public clouds, and VMware Cloud infrastructure.
You can track expenses for a single virtual machine, and identify how these expenses attribute to the overall cost associated with your private cloud accounts and VMware Cloud infrastructure accounts.
On the Cost Overview home page in vRealize Operations Cloud, you can find details about the costs associated with your VMware Cloud infrastructure accounts, public cloud accounts, and your private cloud accounts.

You can view the Total Cost of Ownership, Potential Savings, and Realized Savings for your VMware Cloud infrastructure cloud accounts and vSphere private cloud accounts, and Total Cost of Ownership for your private cloud accounts.
