In a Platform as a Service (PaaS) model, who is responsible for updates and administration of the operating system?

In a Platform as a Service (PaaS) model, the provider is responsible for updates and administration of the operating system. This is because PaaS offerings are designed to abstract the underlying infrastructure and operating system management away from the customer. The primary role of the customer in a PaaS environment is to focus on developing and deploying applications, without the need to handle system-level tasks such as operating system updates, security patches, or resource management.

By having the provider manage the operating system, customers benefit from reduced operational complexity and maintenance overhead. The provider ensures that the underlying platform is secure, updated, and functioning optimally, allowing developers to concentrate on coding and application functionality rather than dealing with the infrastructure details.
