Three tools built for our own use

Diagram of the foundation in five layers: the websites, business applications and products we host; Proxmox VE, clustered machines that restart on another server if theirs goes down; ZFS storage, which copies failover machines to another server every fifteen minutes; backups, encrypted at source every night, with a copy in Germany and a mirror in France; our servers, in Strasbourg, Roubaix and GravelinesDiagram of the foundation in five layers: the websites, business applications and products we host; Proxmox VE, clustered machines that restart on another server if theirs goes down; ZFS storage, which copies failover machines to another server every fifteen minutes; backups, encrypted at source every night, with a copy in Germany and a mirror in France; our servers, in Strasbourg, Roubaix and Gravelines
