Chapter 1 Discovering the Fundamentals of Your Computing Environment
In This Chapter
▶ Deconstructing cloud concepts
▶ Discovering resource pools/cloud models and services
▶ Evaluating the role of the data center
▶ Finding out how the public cloud fits and when the private cloud shines
How quickly things change. Cloud computing has evolved from a risky and confusing concept to a strategy that organizations large and small are beginning to adopt as part of their overall computing strategy. A few years ago when Hurwitz & Associates wrote Cloud Computing For Dummies, there was plenty of skepticism. Would businesses really be willing to adopt cloud computing? What exactly is cloud computing, and how does it help businesses be more effective?
The market has come a long way in a short amount of time. Today more companies — large and small — are doing everything from prototyping a new application with public clouds to implementing a complex private cloud as a utility to support customers and partners. Indeed, we have moved out of the first phase of this new market. We are now at the stage when customers are starting to ask not whether they should think about cloud computing but what types of cloud computing are best able to meet their business problems. Companies are realizing that they need many different types of cloud services in order to meet a variety of customer needs. Therefore, the idea of combining all forms of cloud models in conjunction with data center services as an amalgam or hybrid is the direction computing is headed. An organization deploys a hybrid cloud when it utilizes public and private clouds together with its data center(s) and there are touch points between at least one or more of the deployment models. For example, it shares data between a public and private cloud.
