Major Types of Cloud Computing:
• Most clouds are mixture of Virtualization technologies, To deal with cloud
computing there are 3 major ways:
• Private Cloud
- Systems and users only have access with other devices inside the same
private cloud or system.
• Public Cloud
- Systems and users interact with devices on public networks, such as the
internet and other clouds.
• Hybrid Cloud
- Combination of private and public clouds.
