Cisco has just released its first Global Cloud Index, and it has a clear message: it doesn’t matter if you’re using applications from your own data centre or from somewhere else, they will be delivered from the cloud. Organization’s data centres will be moving to the cloud in a big way. And, by extension, chances are your own organization will be as much a cloud provider as one outside the firewall. This has interesting ramifications for any organization that maintains its own data centres and for the people who run those data centres.
Cisco’s new index is built on a series of predictions on the growth of global data centres and cloud-based IP traffic. The vendor estimates that global data centre traffic - cloud and non-cloud - will grow four-fold from 2010 to 2015 and reach 4.8 zettabytes annually by 2015 — growing at a rate of 402 exabytes per month by that time.
