Top Four Drivers of Hybrid Cloud Migration


According to Tech Republic, the cloud market is on track to reach $127 billion by 2017. While deployment models such as IaaS and SaaS are experiencing significant growth, cloud strategies are also changing.Rightscale's 2015 State of the Cloud Survey found that 55 percent of enterprises have hybrid cloud projects on the horizon; even companies that have historically used a single cloud are now opting for multiple cloud models. What's behind this move from uni-cloud architecture to diversified models? Here are four top drivers of the hybrid cloud.




As noted by a recent Forbes article, 35 percent of enterprises cite security as the primary reason they're opting for a private cloud. Yet here's the thing: They're not giving up public clouds as a result, simply adding to their tech catalog. Using both private and public clouds in tandem allows companies to pick and choose which data and services are kept behind network firewalls and which are hosted on public-facing clouds, putting local IT in control of security instead of farming this task to third-party providers. In fact, hybrid security is such a draw that evenfederal agencies are now opting for multiple cloud deployments to take advantage of improved defensive controls.




According to Cloud Tech, another compelling driver of hybrid migration is the ability to host testing environments in the public cloud and link them on demand to mission-critical data stored in private clouds. This allows companies to leverage virtually unlimited public resources and effectively “break” new software or services without fear of damage to local networks. When a public instance crashes, enterprises simply spin another and try again. By linking low-latency connections from private stacks to public clouds, it's possible to introduce key elements of critical data, allowing businesses to test performance but keep sensitive data from prying eyes.




No discussion of cloud computing can avoid mention of cost. Historically, public clouds have engineered praise for low prices while private options boast high security with bigger investment. Hybrid clouds walk the line between public savings and private spend by allowing companies to decide where they prefer to allocate IT resources and funding for maximum impact. For example, an enterprise might choose to spend big on public-facing clouds to manage high customer volumes and scale back on private deployments, reserving them for largely unused but critical data that requires an easily auditable network trail. Other companies might opt for large-scale private migrations to handle the transfer of legacy system, but still opt for a small public service to handle CRM or other SaaS deployments.


Disaster Recovery


At first glance, Disaster Recovery might seem like a task best kept close to home, but there are significant advantages to migrating at least some of your recovery workload to public servers. While staying in-house offers the benefit of total control over data and recovery timelines, it also presents the problem of a single failure point: If backup stacks go down in addition to primary servers, there's no way to restore critical files and services. By diversifying DR across multiple geographical locations in the public cloud (or multiple public clouds) companies get the benefit of speedy restoration while decreasing the chances of complete system breakdown — even if more than one data center is affected.


Hybrid cloud migration is rapidly becoming the tech move of choice for public and private industry alike driven by the benefit of improved security, testing environments, better cost control and enhanced disaster recovery.
