Answer 1

Answer:

C. Hardware resources are dynamically allocated as use increases.

Explanation:

Cloud computing is a technique organisations to store and retrieve resources in a remote central database with secure access over the internet. It is able to access large data storage resources that would have cost more if they had implemented one for themselves.

A database or data centre is a online group of servers that is in a subscribed service to authorised users. Storage hardware allocation is dynamic to users, which means that another storage location in issued on every duration of subscription, making it easy to add more storage infrastructure. This defines the scalability of data centres.
