Cloud Storage

What is cloud storage?

  • Cloud storage is a term to describe long term (secondary) storage of data that resides in a remote location, accessible only via a wide area network (Internet)

  • Data is stored on remote servers, typically using magnetic storage (HDD), but increasingly using solid state (SSD)

Advantages

Disadvantages

Reliability – Access data anywhere, any time, from any device

Cost – Typically a monthly/yearly subscription plan

Security – Automatic backups

Availability – No access without an internet connection

Capacity – Endless storage space (cost permitting), uses less space on own device

 

Collaboration – Multiple people can access the same file at the same time

 

the-cloud

Worked Example

Data is increasingly being stored ‘in the cloud’

State two advantages of using cloud storage instead of local storage [2]

How to answer this question

  • A state question worth 2 marks only requires you to identify 2 advantages, they do not require any explanation

Answer

  • enables user to access their data from more places/devices

  • enables user to more easily share data with others

  • cloud storage is automatically backed up by the host
