Infrastructure as a Service (IaaS) providers supply the underlying infrastructure (compute, storage, network) resources that power Frame accounts. You are expected to understand when and under what conditions you are charged for use of these resources. The primary cost drivers for IaaS usage are described in the following table.
|Public Cloud Resource||Cost||Cost Best Practices|
|Virtual machines||Charged when VM instances are powered on||Keep VMs off unless absolutely needed. Use Frame Active Capacity min and buffer or Frame Admin API endpoints to manage when VMs are powered on.|
|Storage||Charged when storage is used||Keep Sandbox disk size small unless there is a need to increase disk size for applications and user files. Regularly review the number of Sandbox, Utility server, profile disk, and personal drive backups to keep what is absolutely necessary.|
