Have we considered adding pooling functionality to Varnish much like what they have in memcached?
Run multiple Varnish(es) and load distributed amongst the identified Varnish server pool.... So an element in Varnish gets hashed and the hash identifies the server in the pool it's on. If the server isn't there or the element isn't there cold lookup to the backend server then we store it where it should be. Seems like an obvious feature - unsure of the performance implications though. The recommendation of load balancers in front on Varnish to facilitate this feature seems costly when talking about F5 gear. The open source solutions require at least two severs dedicated to this load balancing function for sanity sake (which is costly). Finally, Vanish already offers load balancing (although limited) to the back end servers - so lets do the same within Varnish to make sure Varnish scales horizontally and doesn't require these other aids to be deemed totally reliable. _______________________________________________ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc
