10. Worked Examples

Simple conceptual example

A small company runs email on a local server in its office.

• The server needs maintenance.
• If power fails, email stops.
• Storage upgrades require new hardware.
• Security patches depend on internal staff.

The company moves to a cloud-based email platform.

• email is accessed through the internet
• storage scales more easily
• provider handles much of the platform maintenance
• the company still manages users, permissions, and usage policies

Conceptual point: Cloud Technologies do not remove responsibility. They shift how responsibility is divided.
