I'm working for Redpill Linpro, you might have heard of us - we're the main sponsor of Varnish development. We're a bit curious about how Varnish is used, what features are used and what is missing. What does a typical installation look like? The information you would choose to reveal to me would be aggregated and deleted and I promise you I won't use it for any sales activities or harass you in any way. We will pubish the result on this list if the feedback is significant. If you have the time and would like to help us please take some time and answer the questions in a direct mail to me.

Re: Strategies for splitting load across varnish instances? And avoiding single-point-of-failure?
HA PROXY is open spurce and works pretty well. Also you can do load balance based on HAS URL if you want.

Or is the common practice to have just one Varnish server? We have 3 servers. A bit overkill, but then we have redundancy even if one fail. I guess 2 is the minimum option if you have an important site and 99,5% uptime guarantee. (2) How do people avoid single-point-of-failure for Varnish? Do people run Varnish on two servers, amassing similar local caches, but put something in front of the two Varnishes? Or round-robin-DNS? We use a loadbalancer from F5 called BigIP. It's no exactly free, but there are free alternatives that will probably do much of the basic stuff: http://lcic.org/load_balancing.html - Bendik ___ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc ___ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc
