AWS CloudTrail Pricing: Why Data Events Cost 100× More Than Management Events
Management events are free for the first trail. Data events bill $0.10 per 100K — and on a busy S3 bucket that lands at thousands per month. CloudTrail Lake is $2.50/GB ingested plus $0.10/GB-month storage. Insights events analyze every management event for anomalies at $0.35/100K. Most accounts pay 5× more for CloudTrail than they need to.
