You can now automatically adjust the number of Compute instances in an instance pool based on performance metrics such as CPU and memory utilization. This helps you provide consistent performance for your end users during periods of high demand, and helps you reduce your costs during periods of low demand.

You select a performance metric to monitor, and set thresholds that the performance metric must reach to trigger an autoscaling event. When system usage meets a threshold, autoscaling dynamically allocates resources in near-real time. As load increases, instances are automatically provisioned: the instance pool scales out. As load decreases, instances are automatically removed: the instance pool scales in.

For more information, see Autoscaling.
