Question

5NCCA:

Many believe that cloud computing can reduce the total cost of computing and enhance “green computing” (environmental friendly). Why do you believe this to be correct? If you disagree, please explain why?

Answer 1

Answer-

Cloud Computing is the use of applications and software through the medium of internet. In previous times before the entry of the Cloud, people need to go to the physical storage of the server to run the particular programs and applications.

Coming to the total cost of computing, the services do not require much expenditure because there are no huge hardware costs involved. Cloud Computing follows "Pay per use" - Therefore an organization need not worry about the costs and use the services accordingly with the subscription plan. Cloud computing offers flexibility , therefore one can increase the capacity accordingly with it and shrink it after the work is done. This cannot be done for traditional way of computing because there is no flexibility provided there and hence the overall system should be changed, paving way to the increase in the costs. There is a 24x7 availability because one can access the cloud anywhere on the Globe through the medium of Internet: Hence reduction in costs. Cloud computing also doesn't need any trained personnel to maintain the hardware. The buying and the managing of the equipment is done by the Cloud vendor only.

Cloud computing is an environment friendly choice. With the use of it, the server capacity is shared between a number of businesses. Resources are allocated and there will be no idle machines, making the utilization of the machines higher, therefore saving energy. There is a much reduction in the travel by the employees and the staff, because they can access the server through the internet. There is a need for cooling systems if every business has their own in-house servers, resulting in higher business costs and energy. This can be deducted by the use of Cloud Computing because a single cooling layout is sufficient to manage every server in the business environment.
