Which of the following best describes the purpose of cloud database as a service (DBaaS)?

• A. The user is responsible for managing the database
• B. The cloud provider maintains the database and users pay for usage
• C. The service operates without user input
• D. The database management is performed on-premise

Answer: (B)

The purpose of cloud database as a service (DBaaS) is accurately described by the option stating that the cloud provider maintains the database and users pay for usage. In a DBaaS model, users benefit from the convenience of not having to manage the underlying infrastructure, database software, security, backups, and maintenance tasks. Instead, these responsibilities are handled by the cloud provider, allowing users to focus on utilizing the database for their applications without dealing with operational complexities. Furthermore, this model offers scalability and flexibility, as users can adjust their usage based on demand, which aligns with the "pay for usage" aspect. Users typically pay only for the resources they consume, which can lead to cost savings and efficiency compared to traditional on-premise database management. In contrast, the other options suggest scenarios that do not reflect the core principles of DBaaS. For instance, if the user is responsible for managing the database, that typically aligns more with traditional database environments rather than a DBaaS approach. Similarly, stating that the service operates without user input overlooks the fact that users still interact with the database for queries, data management, and application development. Lastly, on-premise database management contrasts sharply with the cloud-based nature of DBaaS, as
