I hope I’m asking this question in the right place.
I have a web service serving widgets with about 500K hits /day. Traffic is expected to double monthly.
It is currenty on VPS with Plesk 8 /Centos 5 / Apache 2/ Php 5.2.6 /Mysql 5.0.45 / Memcached / APC
I’m seeing occasional kmemsize errors and also tcpbuff errors.
To solve this I decided to use Nginx as reverse proxy. Adding Nginx to Plesk systems seems to be problematic, therefore I’m now checking the possiblity of using EC2 instead.
What AMI is recommended for my setting (high traffic PHP web service?) It needs to support millions of requests a day. I need an OS that can be easily maintained by non expert + NGinx and my entire configuration + Security and other essential management features.
