What tool in AWS helps compare the cost of running applications in an on-premises data center versus AWS?

The tool that assists in comparing the cost of running applications in an on-premises data center versus AWS is referred to as the Total Cost of Ownership (TCO). This approach helps organizations assess their existing infrastructure costs against what they would incur if they moved to the cloud.

The TCO calculator provides insights into the various factors influencing cost, including hardware, software, personnel, and operational overhead. It calculates and compares these costs across different deployment models, enabling businesses to make informed decisions about potential migration to AWS. The TCO analysis emphasizes the long-term savings and efficiencies that can be realized through cloud adoption, helping organizations weigh the financial implications of their current operations against AWS offerings.

Other choices, while they might seem relevant, do not specifically serve the purpose of a direct cost comparison between on-premises setups and AWS cloud solutions in the same structured way.
