Calculate hidden cloud storage costs compared with HPE, AWS, and Azure


Cloud storage cost calculator_blog.jpgIn my last post I talked about the obvious cloud storage capacity costs as well as five hidden cloud storage costs you may not be aware of: performance costs, snapshot costs, clone/copy costs, support costs, and data egress costs.

Calculating all these hidden costs across multiple cloud vendors is not an easy task. That's why we here at HPE created a Cloud Storage Cost Calculator and comparison tool. It allows you to calculate all cloud storage costsincluding the hidden costsfor HPE Cloud Volumes, AWS Elastic Block Storage (EBS), and Azure Managed Disks/SSDs. Here’s the Cloud Storage Cost Calculator. Go ahead and test it out with your own numbers.

Now, let’s look at an example calculation from the calculator for an environment with 20TB of cloud block storage. We estimate an average volume size of 100GB and moderate performance of 200 IOPS per volume. We also estimate about 10% of the data volumes will be cloned or copied with up to 5 copies each.Cloud_calc_input.png

After the basic inputs, you can specify how much data you want to move and use for multicloud and hybrid cloud. In this case we estimate 20% of data maybe shared between multiple clouds, with 20% of data coming in from on-premises and 10% coming back from the cloud for the hybrid cloud environment.Cloud_calc_multi.png

It’s that simple, a couple of screens and few inputs later—and below is your cost estimates and comparison.Cloud_calc_output.png

All costs compared

A quick look at the tables and charts and you can see HPE Cloud Volumes ($6,313) comes in significantly lower than both AWS EBS ($8,641) and Azure Managed Disks ($9,704).* Even cooler is HPE Cloud Volumes has an annual prepay option so you can save an additional 15% (discount was applied—but even without it HPE Cloud Volumes costs is still significantly lower).  So let’s examine each cost variable in further detail:

Capacity CostsCapacity Costs.jpg

HPE and AWS capacity costs are close, but HPE is still lower based our competitive costs/GB/month and prepay discount. Azure is significantly more, almost double the costs of HPE. The reason? It’s their t-shirt-based sizing for both capacity (GB) and performance (IOPS), where you need to upsize to 128GB per volume even though you only need 100GB. Therefore, paying for capacity that you don’t need.

 Performance CostsPerformance Costs.jpg

First off, for both HPE and AWS performance costs are very similar to capacity costs. Therefore, don’t forget about performance! HPE edges AWS with competitive pricing and our prepay discount. Now Azure comes in at $0, which on the surface looks good. But in reality the performance costs were bundled into the capacity costs, which as discussed above you are stuck with specific jumps in sizes and performance. If you need more, you need go up to next more expensive disk size and IOPS.

Snapshot CostsSnapshot Costs.jpg

HPE wins hands down with a mere $15 in snapshot costs. Why? Because HPE Cloud Volumes only charges for changed and new data rather than charging for the full snapshot size. AWS is in the middle, because it does use some compression to reduce the snapshot size, while Azure is the most expensive because it charges for the complete set of used data in the snapshot.

Clone CostsClone Costs.jpg

HPE wins again because copies are not charged for, but rather just the new and changed data added to the clone copies and the IOPS performance required. Costs can be lowered further if the clones require less performance than the original copy. With both AWS and Azure you pay more because you are paying for multiple full copies.

Support CostsSupport Costs.jpg

HPE delivers the lowest support costs and the best support experience. The support costs are not that far apart honestly, but ask yourself what support experience you want to get? Would you like to have quick access to Level 3 engineers that can help you with your entire hybrid cloud environment? HPE delivers that. 

 Data Egress CostsData Egress Costs.jpg

HPE delivers the lowest data egress costs. In fact, HPE does not charge for data egress.  Instead the $369 under HPE is the estimated charge from AWS or Azure when writing data to HPE Cloud Volumes. If your workloads are primarily read-only or you are replicating more data from on-premises for backup or disaster recovery your HPE data egress charges will be much lower if not zero. Conversely, AWS and Azure data egress charges will add up as you move data around your multi-cloud and hybrid cloud environments.

So in this example above HPE Cloud Volumes comes up with the lowest costs overall and in each cost category including hidden costs. That is not to say there are configurations where AWS or Azure may come up cheaper. My goal is to expose the hidden cloud storage costs you may not have known about and provide you with a transparent tool to calculate all these costs and compare against cloud providers.

Above and beyond lower costs, HPE Cloud Volumes is delivering additional value and features in the following areas:

  • Enterprise-grade—with features and reliability like the instant snapshots and clones we talked about as well as bullet proof reliability and data durability.
  • Easy data mobility—that enables hybrid and multi-cloud. We only talked about data egress costs here, but in fact we did NOT include the costs of migration appliances like AWS Snowball or Azure StorSimple which add to the costs and complexity of implementing hybrid cloud or multi-cloud. With HPE, data can be moved to cloud directly from our storage arrays without the need for additional hardware.
  • Global visibility—that is AI-driven and delivered by HPE InfoSight to provide you with visibility of your entire hybrid cloud environment as well as keep your cloud storage costs under control.

Summing it up

Let me take a final look what I’ve discussed here around global visibility and predicting and controlling cloud storage costs. HPE is delivering the broadest set of cloud storage cost visibility tools in the market. As I talked about in my first blog around predicting cloud storage costs with HPE InfoSight, we have:

  • Real-time cloud storage costs estimates—available directly on the HPE Cloud Volumes portal
  • Predictive cloud storage costs estimates—available on HPE Infosight based on your real data sets
  • Cloud storage costs comparisons—including all the hidden costs you may have not thought about described in detail here and my last blog.

With HPE, you no longer need to fear surprise and hidden cloud costs. We have all your bases covered!
