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
