Based on the concept of consuming computer resources with the help of remote server and software network groups, the "cloud" and/or "cloud applications" are actually interchangeable because of their reliance on centralized, secure data storage. Fundamental characteristics of the cloud include the ability to allow users to access an off-site (location and device independent) infrastructure via a web browser, enhance maintenance of cloud applications through multi-tenancy and increased productivity as hundreds of users could manage the same information simultaneously.
