Thank you for your input.

All your points are valid and can be included in the contract: - We'll be the ones to choose the cloud provider, - We'll take servers that are big enough, - The client should upgrade their server according to our specs, - Upgrades are mandatory.

Any idea what other (simpler) recovery plans we can have besides on-premise?

You could demonstrate the app working on a different cloud platform. If you can make it work on Azure for example that could satisfy them that you have a backup plan.
