Amazon Compute Optimizer now provides cost and performance optimization recommendations for 37 new EC2 instances types, including bare metal instances (m6g.metal) and compute optimized instances . Additionally, Amazon Compute Optimizer now analyzes the “Available Mbytes”, “Available Kbytes”, and “Available Bytes” metrics to deliver more accurate EC2 instance recommendations for EC2 Windows instances.

With this launch, Amazon Compute Optimizer now supports a total of 425 EC2 instance types. Previously, Amazon Compute Optimizer only analyzed “Memory % Committed Bytes in Use” as memory metric for EC2 Windows instances. Amazon Compute Optimizer now uses “Available Mbytes”, “Available Kbytes”, and “Available Bytes” as preferred memory metrics, which are more accurate measures of physical memory utilization excluding the impact of pagefile. When “Available Mbytes”, “Available Kbytes”, and “Available Bytes” metrics are not available, Amazon Compute Optimizer will fall back to use “Memory % Committed Bytes in Use” metric as memory metric.

The new features are now available in Amazon Web Services China (Beijing) Region, operated by Sinnet, and Amazon Web Services China (Ningxia) Region, operated by NWCD.

You can configure Amazon CloudWatch Agent to report “Available Mbytes”, “Available Kbytes”, and “Available Bytes” to Amazon Compute Optimizer.
