Scalability question

[gogaxxe]

Hi,

 

I am a newbie to prestashop. I am thinking of migrating my current store to prestashop.

I have a basic question regarding the scalability of prestashop. I want to deploy prestashop on AWS for auto scaling. For this to be possible the prestashop code base needs to be "stateless". I am not sure if that is the case. I want to be able to add/remove frontend servers as and when I experience traffic spikes. For this to happen the frontend filesystem shouldn't store any session information. Otherwise my customers will see their carts disappear when they are moved from one frontend server to another. Please let me know if prestashop stores any session information in the filesystem (is it stateless?).

I understand that product specific folders like "img" need to be stored remotely so that they are available for all frontend servers.

 

Thanks for your support.
