3. What is a Cloud Database ?
“A database accessible to clients from the cloud and delivered to users on demand via the Internet from a cloud database provider's servers. Also referred to as Database-as-a-Service (DBaaS), cloud databases can use cloud computing to achieve optimized scaling, high availability, multi-tenancy and effective resource allocation.”
