We are excited to announce Amazon CloudWatch Logs Infrequent Access (Logs IA), a new log class for cost-effectively consolidating all your logs natively on AWS, helping to improve visibility into your overall application health. CloudWatch Logs IA offers a subset of CloudWatch Logs’ capabilities including managed ingestion, cross-account log analytics, and encryption with a lower per GB ingestion price making Logs IA ideal for ad-hoc querying and after-the-fact forensic analysis on infrequently accessed logs.
