Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, and more, over the internet, i.e., the cloud. This means that businesses can access these services on-demand, without the need for direct management of the underlying infrastructure.

The benefits of cloud computing include flexibility, scalability, cost-efficiency, and the ability to access resources from anywhere with an internet connection. Unlike traditional computing, where organizations manage their own physical servers and infrastructure, cloud computing allows for the outsourcing of these responsibilities to third-party service providers.

Furthermore, cloud computing offers applications in modern businesses by enabling them to efficiently store, process, and analyze data, build and host websites and applications, implement machine learning and AI technologies, and support remote working and collaboration through cloud-based productivity tools. Additionally, it facilitates disaster recovery, provides a platform for testing and development, and supports the Internet of Things (IoT) applications.
