Correct Answer: AUsing a cloud computing service is generally simple and straightforward. Users can choose an instance with their desired specifications, complete the payment process, and start using the instance right away. Cloud service providers handle the underlying physical hardware, including server maintenance, infrastructure scaling, and hardware upgrades, making it transparent to users. This abstraction of the physical infrastructure is one of the key benefits of cloud computing, as users can focus on their applications and services without the need to manage the underlying hardware.
