Which deployment model is characterized by quick setup and scalability?

The public cloud deployment model is characterized by quick setup and scalability due to its inherent design and infrastructure. In a public cloud environment, resources such as computing power, storage, and networking can be provisioned on-demand and managed by a third-party service provider. This allows organizations to rapidly deploy applications and services without the need for extensive upfront investment or configuration typical of on-premises installations.

One key advantage of using a public cloud model is its ability to scale resources up or down as needed. Businesses can easily adjust capacity to accommodate varying workloads, which is especially useful for handling peak usage times without the need for permanent infrastructure investments. Furthermore, the maintenance and management of the underlying hardware and software are handled by the cloud provider, which accelerates setup times and allows organizations to focus more on their core business activities.

In contrast, the on-premises model typically involves significant upfront investment in hardware and requires lengthy deployment times, as organizations must configure and maintain their physical infrastructure. The private cloud offers some benefits similar to the public cloud but often includes higher costs and less flexibility in terms of immediate scalability. Teradata Everywhere provides a hybrid approach that can also facilitate flexibility, but it does not emphasize the speed of deployment and scalability as distinctly as the public cloud option.
