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.
A basic requirement for cloud services is the ability to access the resources from thick or thin clients irrespective of heterogeneity as far as client applications are concerned. The customer works under the impression of a single pool of data and services though they are located on different geographic locations. It is also likely that the system will automatically oversee the usage of resources based on the access rights reserved by a particular customer or client node.
The capabilities a given system offers to its client can be described by various paradigms. For instance Software as a Service (SaaS) models depict a scenario where a user applies a program that has been stored on a server by the provider. Another model called the Platform as a Service (PaaS) allows clients to make use of applications that have been created by other clients.
Cloud services can also be described in terms of deployment models to depict the designated users. In the private cloud, only one organization reserves the rights to use computing resources located on or off the premises. It may also happen that a third party is involved in the facilitation of networking for accessing the said resources.
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.
