It depends on the IT situation. If it were my client, and they were moving away from on prem. servers, I would spin them up their own cloud server. That would give them the option to put whatever they want on there.
If not, it runs pretty well over Citrix, which is what many of the hosting companies use, and can even give the appearance of being a native app. (Meaning no second start button).

Sage doesn't offer Sage 100 hosting directly. There are many providers that will host Sage for you. Check with your partner and see if they have a preferred provider.

Sage doesn't really offer Sage 100 online, you will need to host your on-premises Sage 100 in the cloud with a Sage cloud hosting provider to give you this functionality.

As Sage consultants, we also offer a secure virtual private cloud hosting service for Sage 100 users. Your best option for hosting Sage 100 online is to work with a Sage hosting provider that has experience with supporting Sage 100. It makes all the difference.
