Defining the Cloud

There are several definitions of cloud computing. The basic notion of cloud computing refers to the technology infrastructure model that enables several types of computing tasks to be performed over a network. The network can be a local area network or a wide area network like the Internet. The network will depend on the type of cloud—a private or public cloud computing service. A cloud computing infrastructure is composed of several types of hardware components (servers, storage systems, network components, etc.), software application components (programs, services, protocols, etc.), and information—the basic component of a cloud (Figure 1.).

If we consider the technological components previously mentioned, it’s evident that many are used to perform an organization’s daily tasks. Currently networks, servers, applications, and other technology tools are used to develop much of the computing processes in an organization. So, what is the difference between a traditional computing model and a cloud infrastructure?

While a traditional computing model infrastructure is based on resources such as hardware components (servers, storage devices or applications like enterprise resource planning [ERP], customer relationship management [CRM], and others), and business information, a cloud computing model infrastructure is based on services. This approach is different: in a traditional computing model all resources interact and affect the general infrastructure whereas the service oriented architecture (SOA) of a cloud computing model creates a more natural separation between two main layers. One is formed by the technology within the cloud infrastructure (computing hardware and applications) and the other is formed by information resources. Services can be configured, provisioned, or escalated internally without end user intervention or awareness. In a traditional computing system, it is more difficult to achieve the separation between the technical infrastructure and the functional infrastructure of the computing module (Figure 2.)
