Public Cloud Server Provisioning

C.

The scenario described in the question best describes the concept of user self-service. User self-service is a cloud computing model in which end-users are empowered to create, modify, or manage their cloud computing resources and services without the need for IT assistance.

In this case, the developer is leveraging a public cloud service provider to provision servers. The company's cloud engineer has created templates that the developer can use to provision the servers, without needing assistance from the IT team. This is an example of self-service, as the developer can provision servers on their own, without the need for manual intervention or assistance.

Subscription services refer to the payment model used for cloud services, where the customer pays a recurring fee for access to the service. Containerization is a method of packaging software in a portable and isolated environment, which is not relevant to the scenario described in the question. Autonomous environments refer to systems that can operate without human intervention or with minimal supervision, which is also not relevant to the scenario described in the question.

Therefore, the best answer is C. User self-service.
