(Answer) (Category) LON-CAPA User Help : (Category) Server System Administration :
How Transparent is Load-balancing to the users?
Nearly transparent. If they log-in to one server and it decides it is overloaded, it will ask the other servers for their load measures. If an alternate server isn't overloaded, the only change the student should notice is that the URL is now changed.
Otherwise everything should look and act the same.
Load balancing is done when logging in and at no other time.
Once logged in the user does not shift between machines.
