Cloud computing involves accessing applications, storing data, and using computer resources over the internet through a web browser rather than on a local computer. The cloud contains servers, networks, and storage in physical data centers maintained by cloud service providers. Businesses can save money with cloud computing through lower upfront costs, scalability, reduced maintenance needs, and pay-as-you-go pricing models. Common cloud services include infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), email hosting, collaboration tools, backup storage, and more. While cloud computing provides benefits, it also carries risks related to internet reliability, legal agreements, security, and privacy.
