One of the economic sectors with the greatest degree of changing technology is the communication industry. Cloud service providers have seen an increase in demand for their services after corporations started realizing the power of clouds in enhancing customer interaction. In this era of computer integration in the corporate sector, it is paramount that firms be prepared to change to remain competitive in the economy.
The concept of cloud computing is still in the developmental stages and much has to be learned about how to use it efficiently. It is essentially a model that enables sharing of a pool of computing resources while managing access and starvation issues. This calls for a system that will be able to handle user requests without the need for human assistance.
Remote access should be supported so that users can operate from heterogeneous thick or thin clients without experiencing technical hitches. The resources owned by the provider are geographically distributed but they appear as one pool to the customer. The customer makes use of resources such as processors, memory or files without knowing their physical location. Above all, the system must have a means of service restriction depending on the access rights of a user account.
Three models have been described based on the capabilities they present to the end user. The software as a service (SaaS)model allows customers to run applications belonging to the provider on a cloud. On the other hand Platform as a Service(PaaS) model allows distributed customers to use other consumer created applications in the hosting environment.
Many deployment models have been declared based on the access restrictions of clouds. Private clouds will only be used by members of the organization registered as the owner. The holding facility could either be located at their premises or at another location, sometimes under the jurisdiction of a third party firm.
Community clouds are reserved for consumer belonging to groups formed jointly by different organizations. A public cloud just as the name implies is freely accessible to members of the public and is maintained by academic or federal organizations. Hybrid clouds result from a combination of the ideas used in the first two categories.
The idea of a mainframe serving thin clients was established in the late fifties and has played a significant role in the development of present day architectures. These forms of distribution are associated with better efficiency, performance and reliability in the event of accidental data loss. Maintenance operations also tend to be less hectic in contrast to a setting where applications to be checked are installed on each computer in a network. With distribution, firms can take advantage of favorable business environments in a distant location.
Cloud service providers always find themselves under attacks from groups concerned about the security of data on transit. Various techniques of encryption have been tried to thwart the effort of system hackers. So large is the insecurity issue that terms such as malicious insiders, bug developers and password eavesdroppers have been coined. Nevertheless, this technology is bound to grow in popularity as the usage of computers is on the rise.
