The number of servers migrated to AWS is indeed a factor when calculating Total Cost of Ownership (TCO) for the AWS Cloud. TCO analysis considers various cost components including:

• Infrastructure costs: Number of servers, storage, networking resources
• Migration costs: Costs associated with moving workloads to AWS
• Operational costs: Maintenance, monitoring, and management expenses
• Personnel costs: Staff required to manage the cloud environment
• Software licensing costs: Any required software licenses
• Data transfer costs: Network bandwidth and data transfer charges

When calculating TCO, the number of servers is a key input that affects compute costs, storage requirements, and overall infrastructure expenses in the AWS environment.
