This EDUCAUSE Executive Briefing explains "What Campus Leaders Need to Know About Cloud Computing". Cloud computing is a computing model in which technology resources are delivered over the Internet. Rather than implementing and maintaining IT services locally, customers of cloud computing buy IT capabilities from providers that manage the hardware and software that operate those services. Resources including infrastructure, software, processing power, and storage are available from the cloud. Cloud computing can provide greater flexibility and improved levels of service, while making costs more transparent and increasing institutional efficiency.
