| **Right-Sizing** | **Comfort factor** | This is the buffer applied during assessment. It's a multiplying factor used with performance metrics of CPU, RAM, disk, and network data for VMs. It accounts for issues like seasonal usage, short performance history, and likely increases in future usage. The comfort factor is applied irrespective of type of assessment (As-is on premises or performance based). For **performance-based** assessment, it's multiplied with utilization value of the resources, whereas for **As-is on premises** assessment it's multiplied by allocated resources. <br> The default values change. <br> For example, a 10-core VM with 20% utilization normally results in a two-core VM. With a comfort factor of 2.0, the result is a four-core VM instead. |
