What kind of cloud computing service allows users to store data remotely and access it from anywhere?

The correct answer is that a cloud computing service that allows users to store data remotely and access it from anywhere is classified as Storage as a Service (SaaS).

While Software as a Service involves applications that are hosted in the cloud and available via the internet, it primarily focuses on providing software solutions rather than storage. In contrast, Storage as a Service specifically addresses the need for remote data storage, enabling users to upload, store, and retrieve files without worrying about physical storage hardware. This service model ensures that data can be accessed from various devices globally, enhancing flexibility and ease of use.

IaaS is focused on providing virtualized computing resources over the internet, while PaaS offers platforms for developers to build applications. Neither directly pertains to the storage capabilities that are core to Storage as a Service. Therefore, the option highlighting remote storage capabilities clearly aligns with the functionality being described in the question.
