Glossary
Also: Rehosting
A system moves to the cloud almost unchanged, without adapting to cloud characteristics.
The route is fast and low risk because the application does not change. It is the right choice when a data centre contract runs out or hardware is at end of life and the date is not negotiable.
What it does not deliver are the benefits of the cloud. A fixed machine that stood before stands in AWS afterwards, often at a higher price.
