We have been running K2 fairly successfully on a local domain for a number of years,   we are now moving forward with the internet connector and Azure B2C for clients.

Our current Blackperl/Smartforms are on a single server located within our local network with the K2 database on another server. 

Is it ok to expose this server to the internet ?  Or are  there recommended archetictures/installations for this.    (Not heavy load base)
