  • Lessons fall from the cloud, changing data center strategies

    The transformative power of cloud computing is long past the point of being news. The cloud model, after all, has irrevocably changed how IT functions. What's interesting to consider is how cloud technologies and methodologies are changing even how on-premises data centers operate. Lessons learned in the cloud are now being applied on site, adjusting data center strategies in surprising ways.

    When it comes to resource efficiency, the things that hyperscale cloud providers such as Amazon Web Services, Microsoft Azure and Google Cloud Platform accomplish might seem like heroic feats. For sure, server utilization rates in an on-premises environment won't reach the 50%, or better, marks that hyperscale providers hit. Still, rates can be improved by emulating those cloud operators.

    So how has cloud computing altered data center strategies?

    New classes of products, most notably hyper-converged infrastructure and software-defined networking, now exist primarily because large cloud providers built environments that showed the value of these technologies.

    Redundancy architectures, too, are not nearly as rigid as they were. The traditional 2N scheme, in which an organization maintains double the number of infrastructure components needed to run critical operations, is no longer considered the mandatory standard.

    Further efficiency is found in rethinking high availability expectations. With more resilient applications, experts argue, a hardware failure shouldn't be the disruptive event it was in an earlier age.

    These are lessons brought down from the cloud, ones that noticeably alter data center strategies. They show again how the quest for efficient and effective data centers is never quite complete.
