Which practice helps identify trends in cloud spend?

• A. Manual review only
• B. Centralization of rate reductions only
• C. Ignore small changes
• D. Automated anomaly detection and variance reporting

Answer: (D)

Identifying trends in cloud spend relies on continuous, data-driven monitoring rather than ad-hoc checks. Automated anomaly detection tracks spend over time and flags deviations from expected patterns, so you can spot spikes, sudden drops, or shifts in usage as they occur. Variance reporting compares actual spend against budgets or forecasts, making it clear whether those trends are within expected ranges or signaling a drift. Together, these practices reveal direction and volatility in spending, enabling proactive optimization like adjusting rightsizing, reservations, or service usage. Relying on manual review alone is slow and may miss subtle patterns; focusing only on rate reductions ignores how usage and volume drive spend, and ignoring small changes lets gradual trends slip by until they become large issues.
