Over the past decade, cloud services have rapidly become one of the most defining technologies in IT. The hype surrounding cloud services may make it seem like all of an organization’s resources should be migrated to the cloud immediately. There is no denying that, in certain cases, cloud services can be tremendously beneficial. In others, however, a cloud migration probably doesn’t make sense.
Services providers are developing business models to build their own cloud and attract customers to purchase their cloud services including hardware and software infrastructure, middleware platforms, system components, software services, and applications. On the other hand, businesses are building their own private clouds to achieve cost saving and taking the advantage to eliminate time required for requisition and provision of IT resources, improve resources utilization, and increase services responsiveness.
