How Cloud Manager allocates cloud resources

Cloud Manager allocates cloud resources for you when you create volumes using the Volume View. You should understand how Cloud Manager allocates resources to set cost expectations.

Allocation of cloud resources for the initial volume

When you create your first volume, Cloud Manager launches an ONTAP Cloud instance or an ONTAP Cloud HA pair in AWS and purchases Amazon EBS storage for the volume:

This conceptual image shows the AWS resources that Cloud Manager creates for the initial volume: a ONTAP Cloud instance that has an instance type of m4.xlarge or m4.2xlarge and one to four one terabyte EBS encrypted disks.

The size of the initial volume determines the EC2 instance type and the number of EBS disks.

Allocation of cloud resources for additional volumes

When you create additional volumes, Cloud Manager creates the volumes on existing ONTAP Cloud instances or on new ONTAP Cloud instances. Cloud Manager can create a volume on an existing instance if the instance's AWS location and disk type match the requested volume, and if there is enough space.

If Cloud Manager creates a volume on an existing instance, it purchases the required EBS storage, which can be 1 TB or larger disks, depending on the requested volume size.

If Cloud Manager creates a volume on a new instance, it purchases one to six 1 TB EBS disks, just like it did for the initial volume.

NetApp storage efficiency features and storage costs

Cloud Manager automatically enables NetApp storage efficiency features on all volumes. These efficiencies can reduce the total amount of storage that you need:

Thin provisioning
Presents more logical storage to hosts or users than you actually have in your physical storage pool. Instead of preallocating storage space, storage space is allocated dynamically to each volume as data is written.
Deduplication
Improves efficiency by locating identical blocks of data and replacing them with references to a single shared block. This technique reduces storage capacity requirements by eliminating redundant blocks of data that reside in the same volume.
Compression
Reduces the physical capacity required to store data by compressing data within a volume on primary, secondary, and archive storage.

With these features enabled, you might see a difference between your allocated capacity and the purchased AWS capacity, which can result in storage cost savings.
