Cloud computing is the delivery of computing services over the Internet. It allows users to access servers, storage, databases, software and more from anywhere rather than maintaining these resources locally. Some key benefits of cloud computing include reduced costs, accessibility from anywhere, scalability, and automatic updates. Popular cloud services include email, Google Drive, and Google Docs. Major cloud providers like Amazon Web Services, Microsoft Azure, and Google Cloud Platform offer resources that can be accessed on demand from their data centers. Many businesses now use cloud computing to improve productivity, reduce costs, and gain flexibility.
