Service Models for Cloud Databases

D.

The service model that would be used for a database in the cloud is Platform as a Service (PaaS).

PaaS is a cloud computing model in which a third-party provider delivers hardware and software tools, usually those needed for application development, to users over the internet. PaaS provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

In the context of a database in the cloud, PaaS provides a complete platform for developing, deploying, and managing database applications. The PaaS provider takes care of the underlying infrastructure and provides pre-configured database software, which makes it easy for developers to create and manage databases without worrying about the hardware and software configuration.

Infrastructure as a Service (IaaS) would also provide the necessary infrastructure for a database in the cloud. However, IaaS only provides the infrastructure, and the user is responsible for configuring and maintaining the database software. Container as a Service (CaaS) is a newer model that provides a way to run applications in containers, which can include databases, but is not typically used for database management. Software as a Service (SaaS) provides software applications, including database applications, as a service over the internet, but the user does not have control over the underlying infrastructure or software.
