Corporates can take a ‘hybrid’ approach by which they can have a private cloud for some or their computing capabilities and a public cloud for the rest, so they can make a choice at some stage to go fully private cloud or public cloud if they wish, or perhaps switch to another provider for their public cloud. If, however, they completely move over to cloud computing then they should factor in an exit strategy so that they can retrieve their business data and business processes in a coherent form. And they can use multiple cloud providers as a failsafe, too.
But whenever a business moves into the cloud they need to take their people with them. Some employees may associate themselves with particular software applications rather than business functions, and some staff may find it hard to let go of systems they have used or managed, so there is some internal communication work to be done. The best thing to do is to get everyone involved in key decisions about cloud computing by asking them to try out particular services for themselves and to document what they do in their jobs day-to-day. In many cases it is the employees who discover the benefits of cloud computing first, though, and their familiarity with web-based applications means that they have many of the necessary skills in place already.
