The Cloud has been a hot topic in IT departments, including the enterprise. Achieving the advantages of this new way of computing is not as simple as choosing the most popular brand name, however.
Private cloud, public cloud, and specially designed clouds for compliance represent different models of cloud computing environments. Each type of cloud has different advantages, depending on the needs of the organization. There are also different types of cloud computing within each model.
Practically any organization can benefit, but only those companies that choose the right cloud for their needs will get the most out of the technology.
Cloud computing is enabled by virtualization, which is the creation of software-defined and controlled servers. A basic, easy-to-understand definition of cloud computing provided by PC Magazine is “storing and accessing data and programs over the Internet instead of your computer’s hard drive,” while Gartner puts more emphasis on the system being scalable, elastic, and delivered as a service.
Private Cloud delivers data and programs from resources dedicated to the customer. Because resources are not pooled with those of other organizations, private cloud has some specific ideal uses.
Private clouds are typically utilized by companies with sensitive data, management, or workload demands beyond those practical for a shared environment. In the early days of private cloud, some organizations chose to host a private cloud on-premise. The benefits of private cloud are maximized when the organization leverages the data center resources of a reliable cloud provider, like Extilum. This removes the responsibility of providing and maintaining critical redundant systems like cooling, power, networking, storage, and infrastructure that normally lie far outside the core competency of most companies.
