Frequently Asked Questions

What causes high CPU usage on AWS?

Common causes include inefficient application code, high traffic volumes, background cron jobs, and 'noisy neighbor' effects on shared T-series instances.

What is a 'T' series credit exhaustion?

Burstable instances (T2/T3) use a credit system. Once you run out of CPU credits, your performance is throttled to a baseline level, causing apparent high usage.
