Question 1

Isn't AWS Budgets enough?

Accepted Answer

AWS Budgets only fires when you cross a fixed threshold you set manually. It doesn't tell you what caused the spike or what to do. StackAlert uses a 7-day rolling baseline to detect deviations automatically, then delivers a full incident report — root cause, impact estimate, and recommended actions — not just a threshold breach notification.

Question 2

Isn't AWS Cost Anomaly Detection enough?

Accepted Answer

AWS CAD has a 24-hour minimum detection delay, requires 10+ days of warmup per service, and only sends to email or SNS. It also gives you no actionable guidance — just a number. StackAlert detects within the hour and tells you exactly what's causing the spike and what to do about it.

Question 3

Will StackAlert shut down my infrastructure?

Accepted Answer

No. StackAlert recommends actions but does not execute them automatically. It uses a read-only IAM role and never modifies your infrastructure. You stay in control — StackAlert just makes sure you have the information to act fast.

Question 4

Is my AWS data safe?

Accepted Answer

Yes. The Lambda runs inside your own AWS account and reads Cost Explorer data via a read-only IAM role. For the hosted dashboard, StackAlert calls your Cost Explorer API but does not store raw billing data on its servers. GDPR-compliant by architecture.

Question 5

How fast are alerts?

Accepted Answer

StackAlert checks every hour, from the moment it's deployed — no warmup period. A spike that starts at 2am is in your Telegram by 3am. AWS Cost Anomaly Detection has a guaranteed minimum of 24 hours. That's the difference between catching a $50 problem and inheriting a $5,000 one.

Question 6

What does the dashboard do?

Accepted Answer

The dashboard at app.stackalert.app gets you set up in under 60 seconds — no coding required. Click to create an IAM role, pick your alert channels from the UI, and you're done. It also gives you a full historical view: 90-day anomaly timeline, per-service cost trends, multi-account comparison, and notification management — all without touching a config file or environment variable.
