AWS Certified Solutions Architect Professional SAP-C02 Practice Question
A financial services company is planning a large-scale migration of its on-premises data center to AWS. The infrastructure consists of hundreds of virtual machines with varied utilization patterns and numerous applications with complex dependencies. The Chief Financial Officer (CFO) requires a comprehensive and defensible Total Cost of Ownership (TCO) analysis that compares the current 3-year on-premises operational costs against the projected 3-year costs on AWS. The analysis must account for right-sizing of resources based on actual performance.
As a Solutions Architect, which approach should you recommend to generate the most accurate TCO analysis?
Leverage AWS Application Discovery Service (ADS) to collect performance data from the on-premises environment. Use the collected data in AWS Migration Hub to obtain right-sized AWS resource recommendations. Use these recommendations as inputs to the AWS Pricing Calculator to estimate future AWS costs and compare them with the existing on-premises expenditure.
Use AWS Cost Explorer to analyze the potential costs of the target AWS services. For the on-premises costs, use the most recent hardware and software procurement invoices as the baseline for the comparison.
Manually create an inventory of all on-premises servers and their specifications in a spreadsheet. Input these specifications directly into the AWS Pricing Calculator to estimate the cost of equivalent resources. Compare the resulting AWS estimate with the company's current annual IT budget.
Deploy the AWS Schema Conversion Tool (SCT) across all on-premises databases to identify candidates for modernization to Amazon RDS. Use the SCT report to estimate the reduction in licensing costs and present this as the primary driver of TCO savings.
