For the start-up business this is a great advantage. Allowing your EC2 instances, connect directly in a secure way to your small business network with pay as you go plans. The main benefit I see is being able to have EC2 servers, and translate them at your firewall with your own IP. This means it all looks like you. There are some picky clients out there, no offenses. With this feature you get the best of both worlds.
You need to have enough Bandwidth to be able to sustain the traffic that is expected but any good Network expert can help you on that task. I h
ope the Amazon folks keep the good work. Please submit your comments and if you find any good tools, comment about them.
