Dear all, I have a plan to start a new project with this scenario :
1 server for database 1 server for web 1 server for memcache In the future, if the traffic increase, I will add more servers as web server and also memcache. But many developers suggest me to use this scenario : 1 server for database 1 server for web + memcache 1 server for web + memcache Of course with this second scenario, everytime I buy a new server will be configured as web + memcache server. I don't mind at all, but the question is... If i'm using DNS round robin as load balancing method, then user A is handled by server 1, his PHP session also stored on that server 1, but on the second request he is handled by server 2, he won't get his session back, right? How to make this memcache server can 'comunicate' each other? So that user's session won't be broken. Thanks.
