Techopedia Explains Utility Storage
Utility storage is a metered disk storage space that enables end users and organizations to source small to large storage space as and when required. Utility storage works by storage virtualization, a process by which a physical or cloud server allocates virtual storage space within the main physical storage system for all new users.
Because it is implemented on a virtualization layer, utility storage is elastic in nature and can be extended easily on run time, usually without much human intervention. As a result, users are not limited by storage capacity. Amazon Simple Storage Service (S3) is a popular example of utility storage in which users access the remote cloud storage through vendor API and an online management console.
