Cloud Computing frequently is taken to be a term that simply renames common technologies and techniques that we have come to know in IT. It may be interpreted to mean data center hosting and then subsequently dismissed without catching the improvements to hosting called utility computing that permit near realtime, policy-based control of computing resources. Or it may be interpreted to mean only data center hosting rather than understood to be the significant shift in Internet application architecture that it is. Perhaps it is the name. Certainly it is more nebulous than mnemonic, if you’ll pardon the poor pun. We happen to think so too. We’d rather use

While not all of these capabilities exist in today’s clouds, nor are all that do exist fully automated, a good portion of them can be provisioned.

Are the services that are provided by the cloud robust in the enterprise sense? Absolutely … especially if you mean the enterprise as we know it today. While there are important security, privacy and regulatory issues that enterprises need to sort through before full migration to the cloud, and cloud vendors need to strengthen cloud capabilities in these areas before enterprise applications can be effectively hosted in the cloud, there are benefits that cloud technologies do offer today that can be leveraged in the deployment of many enterprise applications. Further, cloud vendors are likely to offer virtual private cloud functionality that quite possibly will (at least temporarily) compensate for current deficiencies as cloud vendors work to address them in a more strategic and long-term way. Migration to the cloud will not be immediate because of issues noted above, and because enterprises need to approach migration in a staged fashion, just as they would undertake any significant technology transition. The first stage of migration is to determine what enterprise infrastructure and applications can be reliably rearchitected using cloud computing technologies today to gain
