cloud computing

cloud computing can be loosely defined as using scalable computing resources provided as a service from outside your environment on a pay-per-use basis. you use only what you need and pay for only what you use. you can access any of the resources that live in the "cloud" at any time and from anywhere across the internet.

one incentive for cloud computing is that it may be more environmentally friendly. first, reducing the number of hardware components needed to run applications on the company's internal data center and replacing them with cloud computing systems reduces energy for running and cooling hardware. by consolidating these systems in remote centers, they can be handled more efficiently as a group.
second, techniques for cloud computing promote telecommuting techniques, such as remote printing and file transfers, potentially reducing the need for office space, buying new furniture, disposing of old furniture, having your office cleaned with chemicals and trash disposed, and so on. they also reduce the need for driving to work and the resulting carbon dioxide emissions.
