What is meant by a cloud operating system?

A cloud operating system refers to a system that provides functionality specifically designed for enabling and managing cloud services, which often falls under the umbrella of platform-as-a-service (PaaS). This type of operating system facilitates the development, execution, and management of applications in a cloud environment, allowing users to leverage scalable resources without having to manage the underlying hardware or low-level software.

By focusing on services offered in the cloud, a cloud operating system abstracts much of the complexity associated with traditional OS management. It provides tools and environments conducive to building and deploying applications, thus streamlining the process for developers and organizations using cloud infrastructure. This approach enables more efficient resource utilization and offers elasticity in operations, which is a fundamental characteristic of cloud computing.

The other options describe concepts that either do not align with the characteristics of a cloud operating system or relate to traditional computing environments rather than cloud-native characteristics.
