Cloud Storage

What is Cloud Storage?

  • Cloud storage is a model of data storage where digital data is stored on remote servers.
  • These servers are maintained, operated and managed by cloud storage service providers.
  • Data stored in the cloud can be accessed from anywhere in the world, as long as there is an internet connection.

Types of Cloud Storage

  • Personal Cloud Storage, also known as mobile cloud storage, allows individuals to store personal data like photos, music, and videos.
  • Public Cloud Storage provides storage services to the general public over the internet.
  • Private Cloud Storage is dedicated to a specific user and provides a greater level of security.
  • Hybrid Cloud Storage is a mix of private and public storage.

Advantages of Cloud Storage

  • Cloud storage can increase accessibility and reliability, provide disaster recovery, and reduce costs for businesses and users.
  • Anyone with an internet connection can access their files, anywhere and at any time.
  • Because data is copied and stored in multiple locations, it can still be accessed even if one server goes down.

Security and Cloud Storage

  • Data encryption is typically used in cloud storage systems. This means data is encoded and can only be decoded (read) by those with a decryption key.
  • However, no system is completely secure. Users must be cautious about what they store in the cloud, and use secure passwords and two-factor authentication where possible.

How Cloud Storage Works

  • Files stored in the cloud are broken down into chunks, then each chunk is encrypted and sent to servers across multiple locations.
  • When a file is needed, the chunks are pulled back together and decrypted.
  • It’s like having a puzzle, breaking it up into pieces, storing the pieces in different locations, and then putting it back together when needed.
