How easy is it to introduce memcached to an existing enterprise application instead of inclusion at project design?
In general, it is very easy. In many languages and environments the changes to the application will be just a few lines, first to attempt to read from the cache when loading data and then fall back to the old method, and to update the cache with information once the data has been read. memcached is designed to be deployed very easily, and you shouldn’t require significant architectural changes to your application to use memcached.
