Who has less control over the function and execution of services in a cloud infrastructure?

The capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).

The cloud computing service model in which a provider’s applications run on a cloud infrastructure and the consumer does not manage or control the underlying infrastructure is known as:
