SigningHub allows the installation of its multiple (load-balanced) instances with an existing installation.
This is useful to meet the modern computing requirements that involves but not limited to efficiently managing concurrent requests from clients, and distributing incoming network traffic across a group of back-end servers.

When you install SigningHub as a load-balanced instance through SigningHub installer, an entry is created in SigningHub database for each SigningHub instance along with its specific machine IP and URL. All the installed instances are then listed in SigningHub Admin, where an admin operator can monitor their current status and modify their machine name or service address as required. Hence providing a smart way of publishing the changes on all the SigningHub instances by using a single interface. 

In this way, SigningHub is configured as a High Availability service, as the network load is automatically shared across multiple servers in a fast and reliable manner.
