Don’t look now, but there has been a shift in thinking around why companies move — or should move — workloads to the cloud. So the reason to go to cloud is no longer price but being able to move fast — deploy, re-deploy, and un-deploy workloads as needed without having to buy servers and software that could become shelfware next week or next month.- http://bit.ly/14fjJRl
