Sorting Out the Public/Private Divide in Cloud Computing

    There are countless options for both public and private cloud infrastructure. But do you understand the difference between the two models? Understanding it is key before migrating.

    Cloud computing has been around for nearly a decade. It’s an intimidatingly complex technology that has advanced and changed faster than many have been able to understand it. Deciding between cloud options has thus become a difficult task. Companies are struggling to decide between private, public, and hybrid cloud, and with no safe “one-size-fits-all” option to fall back on.

    It’s time to clear up all the confusion surrounding the cloud.

    In a recent webinar for CIOs (covered by TechTarget), Gartner Analyst Donna Scott answered important questions about the blurring distinction between private and public cloud—and how companies can leverage their capabilities effectively.

    1. When Should You Use What?

    The public cloud has been the growing trend for the last half decade. While many companies are simply migrating all of their infrastructure to it, not all data is suited for storage there.

    Intellectual property runs the risk of falling into the wrong hands in the unfortunate event of a security breach suffered by a public cloud provider. As Scott put it, in many cases, “You don’t want to share networks. You don’t want to share storage. You don’t want to share compute.”

    For the same reason, companies tend to avoid placing identifiable and/or regulated information on public clouds. Instead, they are placed on on-premises private cloud servers or in a co-location.

    Take a retail bank’s demand deposit account program: "There is not a bank on the planet that would ever put that in a public cloud," President of CIMI Corp. Tom Nolle said in an interview with TechTarget. "The security issues would be insurmountable."

    2. How Will You Calculate Your Costs?

    Given the cloud’s lack of a traditional lifecycle and its countless moving parts, determining the network’s total cost of ownership (TCO) can often prove difficult.

    In a multi-cloud or hybrid cloud infrastructure, finding the TCO means finding the total cost of delivering service. Each cloud provider has their own way of determining TCO, but according to Scott, it really comes down to a fairly simple formula.

    “You’re basically adding up all the costs and dividing by the employees that use it, and that gives you per-user costs,” she said. “So if you’re going to consider going to public cloud, you can compare—and you want to try to compare apples to apples.”

    3. What Complexities Do You Face?

    For one reason or another, most enterprises will not be able to migrate all of their IT operations to a single platform. Most will deploy both on-premises, private, and public cloud resources. The complexity of these hybrid systems creates issues in visibility and resource efficiency that only a powerful remote management tool can solve.

    The Vityl Suite from TeamQuest puts the most vital information about your operation’s infrastructure at your fingertips so that you can make quick, proactive decisions to avoid costly outages and overprovisioning.

    Vityl Adviser gives IT professionals the ability to look at simple, at-a-glance health and risk indicators to know which systems and functions could present a problem in the future, then allocate resources to address it.

    A complex network requires powerful monitoring and management tools. With the Vityl Suite, IT professionals can keep a close eye on their entire infrastructure, whether it’s on-premise, virtualized, or based in the cloud.
