Ask HN: Use individual VPS for each client or one dedicated server

hi HN, just interested in some opinion on running a multi tenant saas. The platform is provided to a client with their own server/database due to the nature of the business. However, for situations like these, do you recommend setting up every client on a single dedicated server (very powerful) OR perhaps using smaller but individual VPS ? Lets say for 100 clients, would you setup each client on their own VPS or will you set all 100 on your single dedicated server ?

Of course, both ways are fine and possible. Just wondering if any of you has dealt with this kind of setup/decision ?

For example, if all clients are setup on a single dedicated server, all of them could go down at the same time if for some reason, the server is down. Of course., with individual VPS, this may not happen but then managing each VPS could add to more work ?
