Cloud computing allows users to access applications and store data over the internet through cloud services instead of locally. It offers various models including public, private, hybrid and community clouds as well as infrastructure, platform and software services. The key benefits are efficiency, cost effectiveness and access to resources online or on demand without needing to install software locally. However, security, privacy and vendor lock-in pose risks to cloud computing that need to be addressed.
