# Total Cost of Ownership (TCO) in Cloud

> Chapter 52 of the Courseiva AZ-900 curriculum — https://courseiva.com/learn/az-900/total-cost-ownership

**Official objective:** 1.4 — Cloud Concepts

## Introduction

This chapter covers Total Cost of Ownership (TCO). AZ-900 tests under 1.4.

## Lifetime Cost

Buying a cheap car might have high maintenance costs. Total cost includes purchase and lifetime operating costs. TCO does the same for infrastructure.

## Core explanation

TCO accounts for all costs: hardware, software, labor, power, cooling. Cloud TCO typically lower than on-premises for most organizations, but varies by workload.

## Real-world context

On-premises: $200k hardware + $50k annual labor + $30k annual power = $280k year-1, $80k subsequent years. Cloud: $100k annual = likely lower TCO long-term.

## Exam focus

Objective 1.4 expects understanding of TCO as a cost comparison tool.

## Step by step

1. **Identify all costs** — Hardware, software, labor, power, cooling are included.
2. **Compare on-premises vs cloud** — Total costs are compared.
3. **Evaluate benefits** — Non-cost factors (agility, scalability) are considered.

## Key takeaways

- Includes all costs: hardware, labor, power, etc.
- Cloud TCO typically lower long-term.
- Supports business case for cloud adoption.

## FAQ
