What is cloud computing?

Cloud computing refers to the delivery of computing services over the internet, which encompasses a wide range of resources and functionalities such as servers, storage, databases, networking, software, and analytics. This model allows organizations and individuals to access and use technology resources without the need to own and manage physical infrastructure. It provides scalability, flexibility, and cost-efficiency, enabling users to leverage computing power and services as needed.

In contrast to other options, which focus on on-premises resources or limited service models, the essence of cloud computing is its reliance on a distributed model that provides ubiquitous access to computing power via the internet. This foundational concept is what distinguishes cloud computing from traditional IT setups, making it accessible not just to enterprises but to a more extensive range of users and applications.
