Hi! I would like to set-up nginix and memcached for a lower memory usage... nginx should listen on port 80 and use memcached to cache requests, or pass requests to Apache which listens on a different port. Thus Apache gets less hits since most things are cached. The question is, does this actually make sense? Did anyone test it? I don't know if it's worth the effort...
google noc guys say it worth the effort, but I sugest U to use: clusters. create a private cluster for apache, private cluster for DB, private cluster for storage, and U'll get bonus the redundance. and as many cluster nodes as U need. U can combine clusters with memcached but it's easier to add more nodes to cluster.
