David Linthicum’s observation (noted today in ZDNet) that private clouds are being used as “points-of-control or interfaces” into public clouds seems to validate a way of working that has been expected for quite some time.
The idea that private clouds can draw upon external (public) compute and storage resources as and when required, would appear to be one that sits well with the concept of the hybrid model of cloud computing. To the end user — in whatever form this might be — the outcome is the same: they get the resources they need in order to get along with what they’re doing.
It certainly makes sense and it reiterates what cloud technology leaders such as VMware have been saying (and that we’ve echoed) for a few years now — that private clouds can work in conjunction with public clouds (vCloud Connector, anyone?).
Vitally, the emergence of public cloud doesn’t mean it has to be “all change!”. If you’ve made a big investment in your private infrastructure, why would you suddenly jettison all of these assets, not to mention the hard work and planning that went into building it? Rather, organisations that have an on-site cloud can benefit from the easy flexibility that public cloud environments offer, by tapping into risk-free resource when it’s required — all the while controlling the big picture from a central point.
You can see for yourself how private and public models can work alongside each other with a two week cloud data centre trial, featuring VMware’s vCloud Connector to link your on-site/off-site cloud. If you have any questions, let us know!
