Cloud Computing: Parsing the Differences of On-Premise Versus Private Cloud
A recent report from Evolve IP headlined that that in their survey of financial industry IT professionals found that they overwhelming thought that their data was far safer in the cloud than on-premises.
Scott Kinka, Chief Technology Officer of Evolve IP, said that “financial organizations have recognized the significant benefits of the cloud and the pace of their adoption, and planned future adoption, is faster than many other industries.”
That’s a ringing endorsement of the benefits of cloud computing.
But what do organization mean when they talk about data in the cloud versus data on-premise?
All may not be what it seems. Digging deeper into the results of the survey, only 9.5 percent of organizations say that the public cloud offers them safety. 58.5 percent said that a better option is a private cloud and another 32 percent said that they preferred on-premise management of their data.
Private clouds can be externally managed and set up as dedicated infrastructure for an organization. But, private cloud infrastructure is also very often set up on-premise and managed by the organization themselves, and is basically a way of architecting a more efficient on-premise infrastructure. As Mary Jo Foley, freelance technology writer, wrote for ZDNet, “the private cloud is just the newest way of talking about an on-premise datacenter. Sure, it’s not exactly the same mainframe-centric datacenter IT admins may have found themselves outfitting a few years ago. But, in a nutshell, server + virtualization technology + integrated security/management/billing = private cloud.”
To understand the numbers better, differentiating between externally versus internally managed private cloud infrastructure might provide more perspective.
