From the conventional phone services, communication service demands are growing in leaps and bounds. Cloud service providers have had to conduct awareness campaigns targeting firms saddled with older technology that inhibits customer interaction. In these times of social media, the bare survival of a given organization is highly dependent on the perceived quality of their customer experience.
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 customer wishing to use cloud services should be able to access the shared resources from any node connected to the system without regard to the user application being run. Due to the transparency employed in these networks, the customer always gets the impression that he is accessing resources located at his node. The best systems will also have an element of access control to promote data authenticity issues.
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.
This concept owes its existence to the architecture of main frames and thin clients that was popular in corporations and learning institutions. Some benefits to be reaped from the use of clouds include increased reliability and performance during disaster recovery. Applications located at fewer servers will also be easier to maintain as compared to a case where they were installed on each node. Multitenancy describes the flexibility of locating resources in the most favorable areas such as those with low power costs.
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.
