Compute and storage reporting is the best resource to help estimate cloud costs for a redundancy option for an on-premises server cluster. Compute and storage reporting provides information about the current usage and performance of the on-premises servers, such as CPU, memory, disk, network, and I/O metrics. This information can help to determine the appropriate cloud service level and configuration that can match or exceed the on-premises capabilities. Compute and storage reporting can also help to identify any underutilized or overprovisioned resources that can be optimized to reduce costs.
