With VOA you can proactively address the health, performance, and capacity management of the IT infrastructure and applications in your virtualized data center, as well as across heterogeneous and hybrid cloud environments, to improve efficiency, performance, and availability.

This tool can provide a different series of analytic reports that assess the configuration, performance, and capacity of your vSphere environment:

• Configuration health: Get a comprehensive report on vSphere configuration errors and security hardening suggestion. See a sample configuration health report at https://www.vmware.com/content/dam/digitalmarketing/vmware/high-touch-eval/pdf/vmw-voa-phase-1-configuration-reporting-en.pdf?exp=b.
• Performance assessment: It is useful to understand performance issues affecting your virtual environment and find possible bottlenecks. See a sample performance bottlenecks report at https://www.vmware.com/content/dam/digitalmarketing/vmware/high-touch-eval/pdf/vmw-voa-phase-2-performance-reporting-en.pdf?exp=b.
• Capacity assessment: This builds a customized capacity optimization report based on current usage and trends, which is useful for reclaiming underutilized resources or identifying over-provisioned VMs. See a sample capacity utilization report at https://www.vmware.com/content/dam/digitalmarketing/vmware/high-touch-eval/pdf/vmw-voa-phase-3-capacity-reporting-en.pdf?exp=b.
