Cloud Storage
Cloud storage allows users to store files online instead of on local devices.
Benefits include:
- Backup protection
- Remote access
- Scalability
- Easier file sharing
Examples of cloud storage usage:
- Saving documents online
- Backing up mobile devices
- Storing business databases
Scalability
Scalability refers to the ability to increase or decrease resources as needed.
Cloud systems can scale quickly to support:
- More users
- Larger storage requirements
- Increased processing needs
KT0204: Benefits and Risks of Cloud Computing as well as Cloud Characteristics
Cloud computing offers many advantages but also introduces certain risks.
Benefits of Cloud Computing
