Multiple server setup
After my last question at https://digitalocean.com/community/questions/mail-wordpress-hosting I decided to go with 3 servers. 1 for mail, 1 for web (wordpress) and 1 for databases (mysql) Can someone give me an idea in what config to use for each (cpu, ram, disk,...)? Also, how many (smaller) websites could I be able to host with this setup? Thanks!
