Correct me if I'm mis-reading you here, but as far as I can tell, you didn't like an early release of Distributed Director, and so condemned LocalDirector as well. Perhaps you don't have any use for a simple local load balancer. I've found them very useful. I'll happily use a pair of LocalDirectors in H-A mode to scale a farm up to many, many times the capacity of any single component member. For many applications, I'll prefer to place the job of distributing the traffic about the internet contractually in the hands of the provider. If they are doing their job well, they'll be able to carry the traffic out to their borders. I've never tried out Distributed Director. If I wanted wide-area load balancing, I'd try out various alternatives, but I wouldn't approach the problem expecting any of the alternatives to work much better than a round-robin DNS hack. There's a very big difference here. LocalDirector has a job assigned to it that can be done, and can be done well. It brings passive performance tracking to the party, that's its big improvement over its competition. Distributed Director can't in principle do its job as well. Where the LocalDirector's job is to direct traffic to the currently-fastest server in a farm, from the point-of-view of the choke point where the farm hits the net, the job you'd like a Distributed Director to perform is assigning customers to the farm nearest them --- but there's no way to do that without non-standard and explicit assistence from the application. -Bennett
