In a PaaS environment, what does the customer have control over?

In a Platform as a Service (PaaS) environment, the customer primarily has control over the software applications that they develop and deploy on the provided platform. This means they can customize, manage, and optimize their applications to meet specific business needs and objectives. The PaaS model provides the underlying infrastructure and platform functionalities, enabling developers to focus more on coding and application development instead of managing hardware and operating systems.

While customers might have some configurations or settings for the platform, the fundamental aspects of the operating system and the physical hardware are managed by the service provider. This allows developers to leverage cloud functionalities such as scalability, security, and maintenance without the overhead of managing the underlying resources. Thus, the key aspect of control in a PaaS environment lies in the software applications developed by the customer.
