On-demand self-service is a fundamental characteristic of cloud computing that allows users to provision computing resources as needed, without requiring human interaction with the service provider. This feature is a key part of the cloud experience because it enables users to quickly and efficiently access resources such as storage, processing power, and applications through a web interface or API.

This agility and efficiency are central to the cloud computing model, where resources can be acquired instantly based on demand, often leading to cost efficiency and flexibility for businesses. Instead of waiting for IT staff to provision resources manually, users can simply select what they need and deploy it immediately. This not only accelerates the workflow but also promotes a usage-based cost model, contrasting significantly with more traditional IT infrastructure setups.

In contrast, physical data storage typically refers to on-premise, localized solutions rather than the decentralized nature of cloud services. Limited scalability contradicts a primary benefit of cloud computing, which emphasizes the ability to scale resources up or down as required. Finally, high capital expenditure is not aligned with the cloud model, which generally promotes lower upfront costs by allowing users to pay for services as needed, rather than investing heavily in physical infrastructure.
