Yes.

But can they replace the server in Marseille without us going there ? It
seems difficult.

If we buy an old server at 200 euros, even if we need to replace it 3
times, it would still be cheaper than 2000 euros.

We need a server for packagers. But preferably something fast as multiple
people will be building packages at the same time. So the server at 60
euros per month would be better. Or we can buy a dell server with
12 cores, 32GB for 2200 euros :
