I use either a bare-metal server from online.net coupled with LXC to have multiple separated "servers". Or just hosting them on my "server" at home (LXC again)

I use either a bare-metal server from online.net coupled with LXC to have multiple separated "servers". Or just hosting them on my "server" at home (LXC again), which is actually a DIY beefy PC with an i7-4790 3.60GHz CPU, 32 GB RAM, 2 TB (RAID 1) HDD, APC UPS with a ~20 minute battery runtime, 100/100mbit fiber connection.
