Within Platform as a Service (PaaS), which components are managed by the customer?

1. Middleware

2. Applications

3. Data

4. Operating system

The correct answer is: Applications

In a Platform as a Service (PaaS) model, the customer is primarily responsible for managing the applications they develop and deploy on the platform. This means that the customer has control over their application code, configuration, and the specific logic used to meet their business requirements. They focus on building and managing the application, while the PaaS provider takes care of the underlying infrastructure, including servers, storage, networking, and sometimes even middleware. While middleware, data, and the operating system are crucial components in a PaaS environment, these elements are typically managed by the service provider. The provider ensures that middleware solutions are available and properly configured, handles database management systems for data storage, and manages the operating system to provide a stable and secure environment for application execution. Thus, the customer’s role is primarily centered around their applications, making this the correct choice in the context of PaaS.
