Definition - What does Cloud Database mean?
A cloud database is a type of database service that is built, deployed and delivered through a cloud platform. It is primarily a cloud Platform as a Service (PaaS) delivery model that allows organizations, end users and their applications to store, manage and retrieve data from the cloud.
Techopedia explains Cloud Database
A cloud database typically works as a standard database solution that is generally implemented through the installation of database software on top of a computing/infrastructure cloud. It may be directly accessed through a Web browser or a vendor provided API for application and service integration. Unlike a typical database, a cloud database may be scaled on run-time, in which additional instances and resources of storage and computing may be assigned instantly.
Moreover, a cloud database is also delivered as a service, where the vendor directly manages the backend processes of database installation, deployment and resource assignment tasks.
