Public Cloud Services

Choose the best public cloud option for your workload

Get the best value you can from the public cloud

 

You've been hearing how much money you can save by moving some of your workload to the public cloud. But you’re not sure which public cloud to use, which applications to migrate, or how to get there.

Look for the reality behind the hype

Amazon, Microsoft, Google, and other tech giants offer vast storage capacity and computing power through what’s collectively known as the public cloud or commodity cloud.

Their economies of scale can save some IT operations a lot of money. But many organizations find their applications are not cloud ready. For example, their databases are not written to perform efficiently or cost-effectively in the Cloud.

These questions can help you decide:

  • Are your applications written to take advantage of cloud APIs?

  • Are your applications ready to take advantage of scale-up and scale-down utility computing?

  • Are you looking to take advantage of low-cost, highly redundant storage, and you don’t need high speed?

Understand who can benefit

IT shops can take advantage of cheap public cloud services in four situations:

  1. They have big data sets they can store in the cloud without needing fast access. They may be storing secondary or tertiary copies of archival data.

  2. They develop or run applications written to run efficiently in the cloud. The applications use APIs heavily. They use containers and scale-up and scale-down processes. They make relatively few puts and calls to the database.

  3. They don’t need to know exactly where their data physically resides. They don’t care if it’s in a data center in Florida, Georgia, New York, or somewhere else.

  4. They do burst computing. They need big storage or compute resources for a short time. Then they shut everything down until they need it again.

Beware of unexpected costs

Most organizations will pay more for public cloud services than they expect.

That’s because public cloud services structure their fees like electric utilities. They charge for what you use moment by moment. Your bill goes up or down each month, depending on your activity.

Depending on the structure of your applications, your fees are likely to swing wildly. Those fees can be hard to predict. Our clients' experiences with the public cloud suggest that they are often much higher than you thought possible.

Know how your applications are structured

That’s because nearly all legacy software applications are unable to take advantage of scale-up and scale-down of processing power. So compute resource must be reserved for peak processing.

This limitation prevents them from taking advantage of the cost-effectiveness of the public cloud.

If you have high I/O applications, they will consume more IOPs, more CPU cycles, and more memory. Under current public cloud pricing models, you pay more for each.

Understand and mitigate the risks

Use of the public cloud involves these risks:

  • It may be harder to meet compliance and security requirements.
  • You don’t know exactly where your data resides.
  • You’re less likely to get the level of technical support you expect.
  • Public cloud service providers are unlikely to offer SLAs with guaranteed uptime.

When you understand these risks, you can choose ways to avoid, control or mitigate them.
