Who is responsible for installing and maintaining the operating systems in a PaaS environment?

In a Platform as a Service (PaaS) environment, the cloud provider is responsible for installing and maintaining the operating systems. This is a key characteristic of PaaS, as it abstracts much of the underlying infrastructure management away from the customer. The provider handles everything from servers to storage and networking up to the operating system, allowing developers to focus on building and deploying applications without worrying about managing the underlying hardware or operating systems.

This division of responsibilities is designed to streamline the development process, enabling faster deployment and reducing the overhead for organizations. In PaaS, the customer is primarily tasked with developing applications and managing their configurations and data, but they do not have to engage with the operational aspects of the platform, which are maintained by the cloud provider.

This model allows for a more efficient use of resources and fosters innovation, as companies can leverage the capabilities provided by the platform without needing in-depth expertise in the operating systems or the infrastructure.
