Selecting the appropriate service level and quota Edit on GitHub Request doc changes

The cost for Cloud Volumes Service for AWS is based on the service level and the capacity allocated by the quota that you select. Selecting the appropriate service level and quota helps you meet your storage needs at the lowest cost.

All pricing information in this article is based on the list prices as of July 10, 2018. The information is provided for example purposes only and is subject to change.

Considerations

Storage needs include two fundamental aspects:

  • The storage capacity for holding data

  • The storage bandwidth for interacting with data

If you consume more storage capacity than the quota you selected for the volume, the following considerations apply:

  • You will be billed for the additional storage capacity that you consume at the price defined by your service level.

  • The amount of storage bandwidth available to the volume does not increase until you increase the quota size or change the service level.

Service levels

Cloud Volumes Service for AWS supports three service levels. You specify your service level when you create or modify the volume.

The service levels are catered to different storage capacity and storage bandwidth needs:

  • Standard (capacity)

    If you want capacity at the lowest cost, and your bandwidth needs are limited, then the Standard service level might be most appropriate for you. An example is using the volume as a backup target.

    • List Price: $0.15 per GB per month (as of July 10, 2018)

    • Bandwidth: 16 KB of bandwidth per GB provisioned capacity

  • Premium (a balance of capacity and performance)

    If your application has a balanced need for storage capacity and bandwidth, then the Premium service level might be most appropriate for you. This level is less expensive per MB/s than the Standard service level, and it is also less expensive per GB of storage capacity than the Extreme service level.

    • List Price: $0.30 per GB per month (as of July 10, 2018)

    • Bandwidth: 64 KB of bandwidth per GB provisioned capacity

  • Extreme (performance)

    The Extreme service level is least expensive in terms of storage bandwidth. If your application demands storage bandwidth without the associated demand for lots of storage capacity, then the Extreme service level might be most appropriate for you.

    • List Price: $0.40 per GB per month (as of July 10, 2018)

    • Bandwidth: 128 KB of bandwidth per GB provisioned capacity

Quotas

You specify your quota for the volume when you create or modify the volume.

While you would select your service level based on your general, high-level business needs, you should select your quota size based on the specific needs of applications, for example:

  • How much storage space the applications need

  • How much storage bandwidth per second the applications or the users require

Quotas are specified in GBs. A volume’s quota can be set within the range of 1 GB to 100,000 GB (equivalent to 100 TBs).

Bandwidth

The combination of both the service level and the quota you select determines the maximum bandwidth for the volume.

If your applications or users need more bandwidth than your selections, you can change the service level or increase the quota. The changes do not disrupt data access.

Selecting the service level and the quota

To select the most appropriate service level and quota for your needs, you need to know how much capacity and bandwidth you require at the peak or the edge.

Cost comparison for service levels and quotas

The table below compares cost for different service levels and quota sizes. In the table, the leftmost column indicates the capacity, and the other columns define the MB/s available at each capacity point and its cost.

Example 1

For example, your application requires 25 TB of capacity and 100 MB/s of bandwidth. At 25 TB of capacity, the Standard service level would provide 400 MB/s of bandwidth at a cost of $3,750, making Standard the most suitable service level in this case.

Service level and quota selection

Example 2

For example, your application requires 12 TB of capacity and 800 MB/s of peak bandwidth. Although the Extreme service level can meet the demands of the application at the 12 TB mark, it is more cost-effective to select 13 TB at the Premium service level.
