50% Enterprise to Use Hybrid Cloud by 2017

I read this article from Information week Gartner: 50% Of Enterprises Use Hybrid Cloud By 2017 dated. Some exerpt from the article



Gartner predicts that almost half of large enterprises will be engaged in a combined, public/private cloud operation, often described as "hybrid" cloud computing, four years from now.

VMware, IBM and Microsoft have all launched technology initiatives on the strength of the future prospects of hybrid cloud computing. Despite that, Bittman noted that "actual hybrid cloud computing deployments are rare." While three-fourths of those polled predicted hybrid deployments would occur in the next two years, Bittman scaled that optimism back to "nearly half by the end of 2017" for his prediction.

If IT finds public cloud use follows a pattern already established in the private cloud, then it becomes possible, in some cases, to gain the flexibility of adding resources when needed from the public cloud. There will still be limiting factors. Only some public clouds are likely to have a degree of compatibility with a given private cloud. Application-to-application integration may not be possible for many legacy apps. But public/private cloud operations will be a logical outcome of the path many organizations have already started down, Bittman concluded.
