Energy Costs, High or Low???
What will be real impact of cloud computing on energy costs? Will the benefit
really be as good as its presented to be? After further research the environmental
impact of cloud may be good as perceived. The use of virtualization and
centralization may improve efficiency but how about the continually increasing
popularity of cloud computing. Everything we do on our smartphones require the
use of a cloud to stream data. According to Artemis compute cycles determine
how much time to process through cloud hosting. With more and more users
interacting over a cloud more compute cycles will become available for use. How
much depends on the structure of the application. As humans we will until we
cant anymore, which leads to the problems of overuse and abuse. James raises
the question of the efficiency will be consistent over an increased workload in his
article. Of course hardware will need to be upgraded to meet the demand of
users, but will the energy costs be more than the cost to upgrade? The question
can't be answered so easily all of this depends on the amount of users and true
"efficiency" of the cloud's processors.
The way data is distributed is a major way cloud computing sells its trademark of
sustainability. The energy required to deliver compute capacity to the user
directly impacts energy costs. The costs are also a result of how far the user is
from the computing center. The further the user the more it will cost to
distribute data. With distribution being centralized users distance can vary
depending on the location of the distribution center. Those who benefit will be
those with closer proximity than one further away. Would it be better to have
multiple vendors near users or run on-site data centers? The decision lies in the
hands of the firm. For some the switch may be beneficial and for others detrimental.
