Cloud computing1 is a new paradigm in which computing resources such as
processing, memory, and storage are not physically pres-ent at the user’s
location. Instead, a service provider owns and manages these resources, and
users access them via the Internet. For example, Amazon Web Services lets users
store personal data via its Simple Storage Service (S3) and perform
computations on stored data using the Elastic Compute Cloud (EC2). This type of
computing provides many advantages for businesses—including low initial capital
investment, shorter start-up time for new services, lower maintenance and operation
costs, higher utilization through virtual-ization, and easier disaster
recovery—that make cloud computing an attractive option. Reports suggest that
there are several benefits in shifting computing from the desktop to the
cloud.1,2 What about cloud computing for mobile users? The primary constraints
for mobile computing are limited energy and wireless bandwidth. Cloud computing
can provide energy savings as a service to mobile users, though it also poses
some unique challenges.
