Difficulty: MediumAzure Pricing Calculator and TCO Calculator

A financial services institution runs its core transaction processing system on-premises using twenty physical servers. The IT department needs to prepare a financial comparison report showing the cost savings of migrating these workloads to Azure over a five-year period, factoring in on-premises expenses such as physical hardware, electricity, and facilities maintenance. Which tool should the institution use to generate this comparison?

Answer

Total Cost of Ownership (TCO) Calculator
The correct answer is the Total Cost of Ownership (TCO) Calculator. This tool is designed specifically to compare the costs of running an on-premises infrastructure against the costs of hosting equivalent workloads in the Azure cloud over a specified period. It models physical servers, storage arrays, network bandwidth, IT labor, and physical facility maintenance to demonstrate potential migration savings.

Step-by-Step Solution

1
Identify the primary objective of the scenario, which is to compare current on-premises running costs (server infrastructure, electricity, cooling, labor) with equivalent cloud deployment costs over a five-year timeline.
Recognized that the requirement involves a comparison of existing private infrastructure against prospective cloud hosting to calculate potential savings.
This establishes the baseline requirements for a Total Cost of Ownership (TCO) analysis rather than a simple configuration cost estimate.
2
Evaluate the capabilities of the available Azure estimation and cost management tools against the identified objective.
Determined that the Total Cost of Ownership (TCO) Calculator accepts inputs for current on-premises server, storage, network, and labor metrics to output a detailed multi-year comparison report, while the Pricing Calculator only estimates costs for new cloud architectures.
Analyzing tool functions helps select the tool that matches the requirement of evaluating on-premises to cloud cost comparisons.
