I disagree. Clustering is primarily for scalability not reliability (although provides that as well). Performance actually provides little in terms of scalability. Increasing performance has limited usefulness in the ability of an application to scale. Clustering can provide theoretically unlimited scaleability. > Clustering does not give better performance, in > fact, most of the times gives you less performance one of the reasons > is the load balancer. While there may be some small overhead introduced by the load balancer it certainly does not offset the scalability advantages they provide. If you add just one additional instance of the application though a load balancer, it would have to slow the requests down by one half to loose overall scaleability. I'm sure that they do not introduce that level of overhead. The overhead is more likely negligible. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
