S3 and CloudWatch Logs Cost Controls

Cut storage and logging costs without losing needed data. FCAI detects buckets and log groups with outsized spend.

S3 lifecycle and classes

• Enable Intelligent-Tiering for unknown access patterns.
• Lifecycle to IA/Glacier for aged objects; delete expired artifacts.
• Compress objects (gzip/parquet) for large text and analytics.

CloudWatch Logs retention

• Set explicit retention (e.g., 7–30 days for app logs, 90 for audit).
• Use subscription filters to move high-volume logs to S3.
• Avoid excessive metrics filters and high-cardinality labels.

FCAI helps

• Identifies buckets with no lifecycle and log groups with infinite retention.
• Proposes safe retention defaults and auto-PRs for IaC repositories.
