scalable loadbalancer for jetty server

Question

I am creating an application and I want to create it with applications that are fast but also scale. I use java jetty for my servers, cassandra for my database and solr as search engine. What should I use as a loadbalancer infront of the jetty servers so that the whole setup can scale. I've read about mod_jk and apache but I've also read that it doesn't scale to many machines due to beeing programmed in C. What should I use? Should I try and program something myself in java? I want to use non sticky sessions.

Answer 1

So apache would work fine as a reverse proxy, its really more about with what you or your team is familiar with. Without sticky sessions its pretty easy for most things to work. Nginx or Haproxy is probably what your looking for though if need something bigger. To scale it horizontally it is more a trick of not having sticky sessions (which you already have covered) so fronting it with dns round robining would work.

Really not sure what you mean by programming being in C as it really doesn't have anything to do with scaling things horizontally or vertically. Thats more of an architecture thing then the language used to implement it.
