Percentage Resource Utilization
Definition
Measure of cloud compute resource utilization, e.g. Compute (EC2), Block Storage (EBS), or Object Storage (S3). For each resource type, calculate the amount of resources utilized as a percentage of the the total capacity allocated. Resource utilization rates should be considered over time, and as compared to the expected utilization based on the workloads running. Practitioners should also consider average vs. peak utilization rates.
Formula, as published
Compute: CPU Utilization Rate (total consumed quantity in core-hrs or cpu-hrs / Total CPUs Allocated), Memory Utilization Rate (Total Usage in GB / Total Memory Allocated) Volumes: Throughput Utilized / Throughput Provisioned, IOPS Utilized / IOPS provisioned, Storage Utilized / Storage Provisioned (per volume)
