>. Those are separate physical devices each running my one server. Additionally, when a backup runs the data is stored locally as well as on a physical storage device separate from the hardware it is running. Typically clients already have a firewall/router which is used to distribute requests to the various instances. Awesome! Really glad to hear this is the case. But those are all added costs beyond the single physical server you gave the price of. Server cost * number of physical servers you have deployed Cost of your off-server storage Cost of your network appliance doing load balancing It's still probably way less than the AWS bill, but it's not really fair to compare the total price of infrastructure in one environment vs. just a portion of the other.
