What it means
Cloud spending is driven by resource type, quantity, duration, performance tier, data movement, support, and contractual commitment. The model shifts some investment from fixed capacity to variable consumption.
Why it matters
Variable cost can improve agility, but it also requires ownership, forecasting, and controls that traditional procurement processes may not provide.
Practical focus
- Estimate total workload cost, including data transfer and operations
- Choose commitment models only after understanding stable demand
- Review cost alongside service value and risk
Common mistakes
- Comparing cloud price only to server purchase cost
- Ignoring idle resources and data-transfer charges
- Using discounts to justify unnecessary capacity
