One of the biggest advantages of AWS is that subsequent requests are h= andled within the same process, which allows to retain arbitrary informatio= n between requests without any additional complications. Moreover, all such= program-level caching is type-safe and properly structured. The only reason to use memcached with AWS could be to use it as a shared re= source for several AWS instances, but depending on particular scenario othe= r solutions might be more appropriate. In general, memcached was invented a= s a solution to problems that don't exist with AWS. > Performance I assume is awesome.

The major other factor to use AWS is that the whole webservice can be deplo= yed as a single executable, which allows to benefit from the capability of = the compiler and linker to verify consistency of the whole program. I belie= ve that this single feature alone allows to get rid of most of the deployme= nt failures that usually happen with script-oriented techniques. This is ac= tually my major motivation for using AWS, with performance being much furth= er on the list. --=20 Maciej Sobczak * http://www.msobczak.com * http://www.inspirel.com
