A database (DB) is a systematically organised collection data and information stored on a  computer or on a network storage device. A cloud database functions similar to a traditional database but is implemented on a cloud computing infrastructure, whether it is a private, public or a hybrid cloud. A cloud database can only be accessed through a web interface or through applications that have integrated cloud-provided application programming interfaces.

Points to Remember

  • The cloud database functionality is commonly offered by cloud providers as an integrated service called Database as a Service (DaaS). In the DaaS service model, cloud providers handle all the backend processes associated with the database installation, deployment and resource allocation. 
  • As compared to the traditional database, a cloud database is highly flexible and scalable. Additional instances, computing and storage resources can be instantly assigned to a cloud database as the need arises. Microsoft Azure SQL Database, Amazon Relational Database Service, Clustrix Database as a Service, Google Cloud SQL, and Oracle Database Cloud Service are a few examples of DaaS.
