4.18 – Cloud Storage

Computer Science Revision

Cloud Storage is a service where files can be uploaded via the Internet to a remote server.

The data is then stored on HDDs and SSDs in data centres all around the world.

The advantages of Cloud Storage include:

• Files and applications can be accessed from any Internet-connected device anywhere in the world.
• Files stored in the cloud can be shared easily, often by just sending someone a link to the file.
• Working with other people is easier when the files are stored in the Cloud.
• There is no need to buy potentially expensive hardware to store the data yourself.
• There is no need for a company to hire IT staff to manage the hardware.
• Security and backup is managed by the host company so you don't need to worry about it.

The disadvantages of Cloud Storage include:

• An Internet connection is required to access the files.
• You are dependent on the host company to manage the security and backup of your files properly.
• Cloud data could be targeted by hackers more easily than locally-stored data.
• It is unclear who legally owns the data that is stored on the cloud.
• Ongoing subscription fees may become expensive in the long term.

Would it be wise for classified documents to be stored on the Cloud?

Tap/click to reveal No: Cloud Storage servers are often targeted by hackers, and it may be unclear who legally owns the data, which is not good for classified documents.
