Not really a user of TripAdvisor but damn are they using these servers efficiently? I have difficulty buying these numbers. Especially considering each one has 6.5 compute units with 17.1GiB of ra... and this is their frontend stuff. Not sure what kinda tasks/db they're running in the backend to require another 70 machines considering they're using 32 memcache machines. Can you imagine even say 30 mongodb sharded instances at 17.1Gib each?
