Google Cloud TCO Calculator
Google Cloud's TCO calculator allows you to input on-premises infrastructure details and estimate cloud costs, including compute, storage, network, and operational savings. The Pricing Calculator is for estimating cloud costs but does not compare on-prem vs cloud. Active Assist is for optimization recommendations, not TCO analysis.
