What is a key characteristic of the platform as a service model?

  1. The customer uses an application provided via a cloud infrastructure.

  2. The customer can run his or her own applications that are typically designed using tools provided by the service provider.

  3. The customer is provided with the basic capabilities of processing, storage, and networking.

  4. The customer manages the licenses for the operating systems being used.

The platform as a service (PaaS) model is primarily characterized by its ability to provide customers with a platform that allows them to develop, test, and deploy their applications without the complexities associated with managing the underlying infrastructure. In this model, customers are given the tools and services needed to build their applications, including databases, development frameworks, middleware, and more, which are typically offered by the service provider. This flexibility enables developers to focus on writing code and creating applications without worrying about server management, networking, or storage issues, as these aspects are handled by the PaaS provider. Therefore, the answer that reflects the essence of the PaaS model correctly emphasizes the capacity for customers to run their own applications using the development tools provided by the service provider. The other options describe features that either overlap with other service models like SaaS or IaaS or reflect responsibilities that are typically managed differently in a PaaS environment. For instance, using an application provided via a cloud infrastructure (as mentioned in one option) aligns more closely with software as a service (SaaS). Basic capabilities of processing, storage, and networking are core to infrastructure as a service (IaaS), while managing licenses for operating systems is primarily an aspect
