IIS-Tomcat redirector proposal

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).

Questions

  • Is the redirector necessary? Could we just use multiple IP addresses for glast-ground (I don't know of modern web browsers that support this).
  • If the redrector is not available immediately should we plan to register (at least one) IIS server as a web server and move it to the range of IP addresses for port 80 web servers.
  • Any recommended software for synchronizing files between windows boxes (we have used SecondCopy resonably sucessfully in the past).
  • No labels
