While using secure gateway to integrate bluemix and on-prem applications, we can use IBM client installer, Docker or DataPower.
For now, let us consider IBM client installer & Docker.
While configuring the client either through docker or by installing the client, we don't specify the details of the host on which the secure gateway client is running. We provide only the Gateway ID & Security Token. Want to understand how the resolution happens? In other words, how does bluemix connects to the gateway client to establish the connectivity to on-prem resources.
