In PaaS, the customer has control over which aspect?

In a Platform as a Service (PaaS) model, the customer primarily has control over the software that they develop and deploy on the platform. This means the user can implement programming, configure applications, and make decisions regarding the software environment, such as choosing the programming languages, frameworks, and development tools.

PaaS provides a platform that abstracts much of the underlying infrastructure and minimizes the need for the customer to manage the operating system and physical hardware. Instead, the service provider maintains these aspects, allowing customers to focus on building and managing their applications without worrying about the lower-level resources. This focus on software development enables faster application development and deployment, as developers can utilize built-in tools and services provided by the PaaS environment.
