The phrases "cloud computing" and "private cloud" have permeated the technical zeitgeist with a rapidity that we have rarely seen. As a result, we spend a good deal of our time discussing these concepts with our customers, partners, and technical colleagues in an effort to understand what they mean in concrete terms. In an effort to bring some clarity to these ruminations (primarily to myself), I've tried to distill them into a "Top 5" list of questions we are asked and to formulate my opinion of how they can, and in some cases should, be answered.
First, the questions in dramatically paraphrased form are:
- What is a "private cloud" and how is it different from a "public cloud" and a "virtualized data center?"
- Is a private cloud secure?
- How do I build a cloud?
- How do turn a private cloud into a hybrid cloud?
- What will I need to do to my applications to get them to run in a cloud, private or public?
