Cloud computing allows on-demand access to computing resources like servers and networks that can be quickly provisioned with minimal management effort. This contrasts with traditional on-premise IT systems that require upfront investment in hardware and software. The cloud offers several benefits such as lower costs since no upfront investment is required, greater flexibility since resources can be scaled up or down quickly as needed, and improved productivity and innovation since resources are accessible from anywhere. While some concerns around security and control remain for large enterprises, cloud vendors are addressing these issues by providing greater administrative capabilities within their cloud offerings.
