These innovations have improved scalability, efficiency, and digital accessibility.

How Cloud Computing Works

Cloud computing uses networks of interconnected data centers that host computing resources.

A typical workflow includes:

1. A user accesses a cloud-based application.
2. The request is securely transmitted over the internet.
3. Cloud servers process the request.
4. Data is retrieved or stored within cloud infrastructure.
5. Results are delivered back to the user's device.
6. Monitoring systems manage performance and security.

This process allows users to access computing resources from many types of internet-connected devices.
