Hybrid
We talk about a hybrid approach if the relevant parts of the working system are part on-premise and part in one or multiple hyperscalers.
Augment
Instead of replacing core parts we can also just augment an existing core or similar central component with cloud native services while just shifting the core.
Standby
Keep the cloud or another cloud provider on standby in case of an emergency.
Single Cloud
Only use one single cloud provider.
Multi Cloud
Use multiple different cloud providers.
