AWS Compute Optimizer now supports 32-day lookback for EBS volume and ECS service rightsizing recommendations
Amazon Web Services has extended the data lookback period for its Compute Optimizer service, allowing users to analyze up to 32 days of historical data when generating rightsizing recommendations for Amazon EBS volumes and Amazon ECS services, doubling the previous 14-day limit. The enhancement enables the service to capture monthly utilization patterns, including cyclical workloads like month-end processing, to provide more accurate cost and performance optimization recommendations at no additional charge. The extended lookback capability joins existing 32-day analysis options for EC2 instances, Auto Scaling groups, and RDS databases, creating a comprehensive view across AWS compute resources. Organizations can configure the lookback period at the organizational, account, or individual resource level through the AWS console, SDK, or CLI, with availability across all AWS regions except GovCloud and China regions.
Why It Matters
This enhancement addresses a critical gap in cloud cost optimization by accounting for monthly business cycles that shorter analysis windows miss. For enterprises with cyclical workloads or batch processing jobs, the ability to analyze longer usage patterns should result in more accurate rightsizing decisions, potentially reducing both over-provisioning costs and performance issues from under-provisioning.
