services to other organizations and/or individuals, usually for a fee.
Cloud storage
A service that allows customers to save data by transferring it over the Internet or another

that enable interoperability in support of distributed architectures by passing data between
applications. So, for example, the data in one database can be accessed through another
database.
On-demand service

customers need to utilize additional servers for the duration of a project, they can do so and
then drop back to the previous level after the project is completed.
PaaS
Platform as a service — Cloud platform services, whereby the computing platform
(operating system and associated services) is delivered as a service over the Internet by the
