Next, consider the confidentiality controls in place. How are the two servers connecting to each other? Are they...
using SSL or another secure, encrypted protocol? If the servers are using a secure protocol, a VPN connection may add unnecessary overhead to the communication, as each message would be encrypted and decrypted twice. In that case, skip the VPN.
