The Challenge of Traditional Anomaly Detection in Cloud Cost Management

Cloud cost management is complex, dynamic, and highly variable. Traditional cost reporting tools provide historical spending insights, but they fail to highlight inefficiencies in real-time. Likewise, threshold-based anomaly detection methods often generate lots of noise, fail to adapt to known spikes or seasonality, and lack the context required for an efficient investigation and resolution.

“Today’s cost reporting tools show where money was spent but don’t provide insight into why costs are spiking or what to do next.”

The Problem with Threshold-Based Detection

Threshold-based anomaly detection is still the standard Today. It operates on predefined rules, flagging any deviation beyond a set percentage. While this may work for basic monitoring, it quickly falls apart in elastic cloud environments where workloads fluctuate based on demand, deployments, and business cycles. The key limitations include:‍

‍

1. High Manual Effort: Static thresholds require constant tuning, and dynamic thresholds still fail to handle seasonality and long-term trends accurately.‍

2. Lack of Adaptability: Current methods used struggle to account for cloud environments’ evolving nature, leading to frequent false alerts.‍

3. Limited Granularity: Basic threshold-based approaches often lack the ability to drill down into anomalies by region, workload, or time‍

4. Lack of Contextual Insights: Isolated alerts don’t correlate across different metrics, making root cause analysis difficult.‍

5. Reactive Rather Than Proactive: Traditional tools only react to anomalies after they’ve occurred, missing opportunities to prevent cost overruns before they escalate.

Enter AI: The Potential of Smart Anomaly Detection

What is a Smart Anomaly Engine?

Tangent is the first Smart Anomaly Engine for cloud efficiency. It goes beyond traditional cost tracking by leveraging AI-powered anomaly detection to  proactively identify inefficiencies. By modeling expected behavior across different levels of granularity,  Tangent surfaces actionable insights, benchmarks efficiency across teams, and enables organizations to track FinOps maturity over time.

How Better Anomaly Detection Changes the Game

1. Less Noise, More Control

Tangent intelligently filters out predictable spending spikes, seasonal variations, and known correlations to focus only on relevant anomalies. This reduces alert fatigue and ensures teams spend time only on impactful cost deviations.

2. Self-Learning & Adaptive AI                                  

Unlike threshold-based approaches, Tangent continuously evolves with your cloud usage patterns. It automatically detects trends, seasonality, and workload correlations, ensuring more accurate and timely anomaly detection.

3. Transparent Cost-Efficiency Benchmarking

FinOps leaders need more than just spend reports—they need comparative efficiency benchmarks across teams and departments. Tangent provides these insights, allowing organizations to pinpoint wasteful workloads and take corrective action.

4. Actionable, Human-Readable Insights

Tangent provides clear, contextual explanations for each detected anomaly, making it easier for teams to diagnose issues and empower engineers to act.

Focus on What Matters: The 80/20 Rule

“Organizations are overwhelmed by noise, alerts, and minor cost-cutting recommendations while still missing the biggest drivers of waste.”

Most organizations struggle with an overwhelming volume of alerts, many of which lead to minor optimizations. Tangent cuts through the noise by prioritizing the 20% of anomalies responsible for 80% of inefficiencies. Key benefits include:‍

• Less is more – We surface only what’s relevant.

• Expert Time Series Modeling: Uses advanced multivariate modeling to detect important anomalies that now go unnoticed and dynamically adapt to the ever-changing reality

• Explainability Built-In: Ensures every anomaly comes with detailed root cause insights, improving proactive cost control.

‍

Comparing Cost Optimization Strategies

FinOps is not a tool, it’s a practice. So you should ask yourself which capabilities could really strengthen your practice and empower your teams to proactively optimize and effectively govern your cloud operations and efficiency:

“Stop chasing every loose end with isolated fixes. You don’t have the resources to win this uphill battle. Aim at gaining a macro view of cloud inefficiencies instead, so you know exactly where to act for maximum impact”

‍

Conclusions

Cloud cost optimization shouldn’t be about chasing individual cost anomalies without understanding their broader impact. AI-powered Anomaly Detection like Tangent helps organizations pinpoint their biggest cost drivers, benchmark efficiency across teams, and focus on what truly matters:

• Highlighting inefficient spend rather than just reporting totals

• Identifying which teams or workloads contribute the most to waste

• Providing efficiency benchmarks instead of just historical cost data
