How Does Cloud Computing Work?
Imagine having access to a network of incredibly powerful computers at any moment. Your data is processed, stored, and managed by these computers (or servers).
Cloud providers use tools like:
- Virtualization: Splits one computer into many virtual ones to maximize efficiency.
- Resource Pooling: Shares computing power among many users while keeping data private.
- Elasticity: Automatically adjusts resources when your needs change.
