IIS-Tomcat redirector proposal

Image Added

Notes

  • The IIS web servers contain very little content (just documentation "workbook"), and no web applications. All real web applications live on the tomcat servers.
  • Purpose of redirector is just to protect against scheduled or unscheduled outages of the IIS servers. It would be good if it load balanced between the IIS servers just to verify that they are both working and synchronized.
  • All of the tomcat servers are configured identically, except for the web applications they run. It is simple to move web applications manually from one server to another. Initially this will be enough to protect us against outages of the tomcat servers. (Eventually load-balancing/failover would be nice here too, but a lower priority and more complicated).
