While I'm a big fan of haproxy, Apache, and nginx, I will say I also very much like trafficserver as a cache. Compared to squid, which I've always wanted to like but never really have, it is much easier to set up, and it's proven to be very reliable in our use. Specifically, I install it, point it at a large raw disk partition, and drop in my config files (largely consisting of routing rules for where to get the origin based on the request), and trafficserver just goes to town. It's a perfect use case for the ephemeral storage on virtual instances.
