High scalability with CakePHP

Hi
I have a web application where users can uplaod file,images and work
with some datas in db
I use CakePHP ,MySQL,Memcache.
I have a server with Apache and for the file's uploading ( I use Media
Plugin of David Persson).
I have another server with MySQL
For the moment I have 500 users and all works fine.
My problem is that in the next months I can have a very fast increment
of users and this configuration is not sufficient for me.
I have tried to search on Google about how scaling a web app with
CakePHP with scaling of MySql and scaling CDN but I didn't find
anything really concrete I would ask if someone with experience about
this if he can suggest to me something resources (books,articles,code
suggestions) ffrom which I can begin to work.
Many Thanks
