register domain if required
choose droplet, intel is mandatory for being able to scale resize up to other platforms, amd traps in one tier
for power customers with big work forces and / or a lot of printing of large multipage reports a dedicated cpu is important
for hosting we should recommend 2gb shared as the cheapest server practical, but ideally dedicated cpu and ram but that's at least 60 bucks a month
1gb droplet ok if not printing more than 100 pages wo at a time, otherwise fine for most ops
2gb droplet probably more appropriate as a starting point for biz people
on the other hand can easily move up so...
create droplet with ssh keys
create swap file 
    4gb more than enough prevents crash oom
    set swappiness to 10 for server mode
    make sure to save settings to survive reboot
