on demand

Instantly provided. The always-on connectivity of the Internet and the abilty of computers to operate 24x7 has led people to expect automated services to be available whenever they want. This in turn is prompting businesses to adopt a more flexible organizational structure that can quickly adapt to changing market conditions. On demand refers not only to this instant provision of services, but also to the utility computing infrastructure that underpins it, using emerging technologies such as server virtualization, self-healing autonomic systems, and adaptive provisioning.
