Cloud computing is now more than just power for an organization's computer, with the advantage of the technology for access to a grid, as it capitalizes on the economies of scale.

It's easy to confuse the concept of cloud computing with existing solutions and services. Indeed some people assume that it represents an already established solution, cannot really be quantified or is as ethereal at its very name might suggest. Comparable to a grid, the cloud computing seems to be similar to the former for many people. Isn't the very concept of cloud computing entirely reliant on linking computer power together and does it make sense to sell such services as if they represented "something new?" Due to some of these misconceptions, it is important to differentiate the terminology. A great deal more than a grid, cloud computing represents significant opportunity for the average organization.

To enable cloud computing to work, numerous resources are required. Without access to a grid, cloud computing cannot be established and so a multiple of different computer servers must be linked together to form a larger infrastructure, to enable service through the cloud. With the capacity of the server enlarged at a rapid rate, the resource size would allow organizations to take on more complicated tasks that what they rather would have in the first place. Cloud computing could allow organizations to have access to its computer power and resources on an on-demand basis, just like how we use power as we need electricity.

Much more than just a grid, cloud computing provides us with significant flexibility and allows the consumer to undertake its operations "off-site," either through access to software as a service, platform as a service or infrastructure as a service. Imagine having access to software without the hassle of buying it and installing it on local machines, paying individual licensing fees and worrying about maintenance of upgrade schedules? The company may be struggling with its capacity internally and may seek to run these systems on resources made available "in the cloud," not having to worry whether its internal capacity would stand up to the task. Of most significant interest to an organization should be the ability to use cloud computing capacity for an entire, companywide operation.

Essentially, it should no longer be necessary for a company to worry about investing considerable funds in hardware, software and training of personnel equipped to deal with these resources. Now, through access to a worldwide grid, cloud computing presents the opportunity to scale up in capacity instantaneously, an opportunity that would have required considerable advance planning, otherwise.

Using access to grid, it is possible to share resources, though cloud computing could offer inherent freedom and flexibility because capacity is accessible on-demand. Organizations could do away with the expensive provisions needed for the effective management and storage of data through high security, accessibility and reliability through repetition.
