Cloud computing is the on-demand delivery of various IT resources such as compute power, databases, storage, and applications via the internet. It provides these resources in a flexible manner, allowing users to access and utilize them as needed without the requirement for physical hardware management. According to the source, cloud computing enables users to think of their infrastructure as software rather than hardware, emphasizing its flexible, service-oriented nature. The resources are supplied by cloud service providers and are available whenever required, supporting a pay-as-you-go pricing model.
On-demand delivery refers to the ability to access and use IT resources whenever needed, without prior planning or long-term commitments. This approach ensures that resources are available immediately when requested, facilitating rapid deployment and scalability of solutions.
