Experimental Cloud Computing as the 5th Utility:Its Vision and Importance

With the meaningful improvements in Information Technology, it is envisioned that computing facilities will be considered as a 5th utility of the life after the four main utilities i.e. Water, gas, electricity and telephony. This computing utility, will contribute the fundamental stages of computing jobs that is necessary to fulfill all the demands of the public. Various computing prototypes have been introduced and cloud plays an important role.With the passage of time there is an elevation in the computer science field from the half century ago, experts have predicted that one day cloud computing will be used as one of the utility which will be very beneficial for all. With the growing hands in the field of virtualization, it is trusted that this approach has modified the whole IT industry. The cloud computing used as a utility is very important as other four utilities are because cloud provides computing services up to the high end services like virtual space, virtual servers, etc., which are highly essential for satisfying the needs of the user without physically purchasing all the infrastructure. To present this scenario, various computing prototypes have been proposed. After many of the milestones achieved in this field, we are now at a stage where we have almost complete computer ERA, which did not exist in reality, but is accomplishing its task and it is known to us as “Cloud computing”. The author’s aim for purposing this paper is to get the finer understanding about the cloud’s overview and about its advantages and issues.
