- Software program-only: This personal cloud makes use of software program to handle and deploy virtualized assets however doesn’t use devoted {hardware}, and it affords decrease upfront prices however could have much less scalability because of the lack of devoted {hardware}.
- Software program and {hardware}: This personal cloud makes use of each software program and devoted {hardware} for administration and deployment, providing better scalability but additionally larger preliminary prices.
Advantages of personal clouds
Non-public clouds provide a number of advantages when in comparison with public cloud options.
Customization and management
Maybe most significantly, personal clouds ship larger ranges of customization and management. It is because personal cloud environments aren’t shared with different organizations in the best way public clouds are.
