Which Cloud Model primarily uses databases to store data?

The correct choice, which is DBaaS (Database as a Service), primarily utilizes databases to store data. This cloud model is specifically designed to provide a database management system as a service to users without the necessity of managing the underlying hardware or database software. Users can easily access and manage their databases over the cloud, allowing them to focus on their applications and data without the need to handle physical servers or database installations.

DBaaS offers scalability, high availability, backups, and the ability to manage performance requirements, making it an attractive option for businesses looking to leverage the cloud for database solutions. It allows organizations to access robust database technologies while benefiting from reduced administrative overhead and enhanced functionality that comes with cloud-native database services.

In contrast, the other cloud models serve different purposes. SaaS (Software as a Service) delivers software applications to users over the internet, PaaS (Platform as a Service) provides a platform for developers to build and deploy applications, and IaaS (Infrastructure as a Service) offers virtualized computing resources over the internet. These options may include databases but do not specialize solely in database management as DBaaS does.
