AWS launched an intelligent tiering feature for CloudWatch Logs that automatically classifies data into Standard, Infrequent Access, or Archive Instant Access tiers based on usage. This enables long-term log retention at reduced storage costs without impacting query performance, as data is rehydrated on access.
The service monitors access patterns and migrates data accordingly, allowing customers to keep verbose logs natively in CloudWatch instead of exporting or filtering them. While AWS highlights operational efficiency gains, independent assessments of cost savings or performance impact were not included.
