Overview / Technologies¶

We are using a combination of

• OpenNebula:https://opennebula.org/
• Django:https://www.djangoproject.com/
• Heavy focus on IPv6 first (or even only)

Networking in general¶

• Virtual machines are connected to an internal 10 Gbit/s network
• Uplink for all VMs is 1 Gbit/s
• We have a fair use policy:
  • As long as you don't infer / reduce other people's experience, no action will be taken
  • If the VM is using excessive bandwidth over a longer time, we take the right to either throttle or suspend your VM

IPv6 Networking¶

• All our VMs get an IPv6 address assigned to by OpenNebula
• Every customer can request a /64 per VM for free by email
  • This process is going to be replaced by an API in the near future (as of 2018-11-11)
• Additional networkinging options like /56 or /48
  • On request / with a good use case, the price is 5 CHF/month (excl. VAT)

IPv6 address assignements¶

• Currenty the IP addresses are assigned to by OpenNebula using its contextualisation
• The method is SLAAC-alike (embeds the mac) but does not use RAs
• There is no DHCPv6 being used
