Debian
On all our hypervisors we are using Debian, as the most stable linux distribution. Latest version - 12. All updates are smooth and unnoticeable
Proxmox
Yup, that's it. For all virtual machines we are using best virtualisation platform and it's Proxmox. We wrote a lot of customisations. This choice makes out virtual machines very stable.
KVM/Qemu
Under the hood of proxmox, QEMU/KVM used. Full hardware virtualisation with fair usage policies. No overselling for ram and even for cpu.
Python
Python is a core for all customisation. APIs, automations, workers ... Even this is written in python. We love python here, in serverscamp.
Hewlett-Packard
All hypervisors, nodes, others servers - are HP servers. We think that HP is most stable, grown solution to implement best uptime for our virtual machines
