Driving question: What are the features and uses of cloud computing?

Cloud storage

● Cloud storage allows users to

store files and data on
the Internet

● It tends to be more sophisticated

than offline storage

Scalability

● Scalability is the ability of the storage system or cloud computing

resources to increase in size

○ A home PC doesn’t have scalable storage. It may be possible to

have two or three hard disks, but not two or three hundred

● Cloud storage normally charges for the amount of

storage used

○ Increasing offline storage usually requires

the purchase of new disks

Choosing cloud platforms

● Cloud platforms rely on a different company to store and provide

the service. Considerations should be made for the following:

○ The price may increase whilst subscribing to the service
