Executive Summary

• The common thinking of over TCO or total cost of ownership is incorrect.
• TCO makes up the total costs in each comparative solution architecture combination.

Introduction

Various unsubstantiated proposals are frequently made about the different common combinations of application costs. Some quite expensive applications are justified based on a “lower TCO.” What you see below are the only combined comparisons that we know of that have been published.

You can consider this to be a solution architecture document. The intent is to determine the total costs for the different common combinations of IT decisions.

What Makes Up the Total Costs In Each Solution Architecture Combination?

The input to these combinations is based on our TCO analysis.

This compares the costs of a combination of different applications to the total cost. The TCO that we use is comprehensive. It is explained in detail in the TCO section. This solution architecture document is suitable for performing comparative analysis. This analysis type is rarely performed, so IT buyers never wholly understand their solution architecture costs.
