[Koha] Suggestion for a Debian Managed VPS

Hello everyone, I'm going to quit my old koha installation running on a Centos VPS and I would like to switch to a new Debian VPS (so I can install and manage Koha more easily). However, I'm having a lot of difficulty choosing a hosting provider: in fact, my old Centos VPS was Fully Managed (i mean that the Hosting Provider take care of the general security, the update and the backup of the VPS, and that they have a ticketing system for all the technical issues), but at the moment I haven't found hosting provider that offer a Fully Managed VPS with Debian. Does anyone have any suggestions related to this topic? Thanks! Alessandro
