* Docker or "container" provisionning - we consider this out of scope
for now
* self-provisionning by end-users: TPA remains in control of
provisionning
A budget was proposed by weasel in may 2019 and approved by Vegas in
June. An extension to the budget was approved in january 2020 by
Vegas.
## Proposed Solution
Setup a Ganeti cluster of two machines with a Hetzner vSwitch backend.
The design based on the [PX62 line][PX62-NVMe] has the following monthly cost
structure:
* per server: 118EUR (79EUR + 39EUR for 2x10TB HDDs)
* IPv4 space: 35.29EUR (/27)
* IPv6 space: 8.40EUR (/64)
* bandwidth cost: 1EUR/TB (currently 38EUR)
At three servers, that adds up to around 435EUR/mth. Up to date costs
are available in the [Tor VM hosts.xlsx](https://nc.torproject.net/apps/onlyoffice/5395) spreadsheet.
