Web Application Caching Architecture

I am designing a website implementation. There are two web server machines and we would like out-of-process global cache provided by Memcached.

I envisage placing memcached on two开发者_Go百科 separate boxes whose sole purpose is to serve the global data cache. Would such an implementation be considered "typical" and would the term "cache server" be appropriate to describe those machines?

Sounds like you're on the right track. This does sounds like a typical implementation to me.

By saying "I envisage placing memcached on two separate boxes" I hope you dont mean using two servers both having memcached. If so you should divide your caching to these two servers like first server caching data from tables(A,B,C) and the second caching (D,E,F)
