Hi Rahul,
Please find my settings: URL: https://gist.github.com/sadc/6661506
I use AWS EC2 with Security Group ... , [Debian OS], Haproxy, Varnish, Nginx, Memcached, php5-fpm, mysql, Naxsi, fail2ban, iptables, Wordpress and few wordpress plugins such as W3 Total Cache (latest version with one bug correction) (NOTE: do not use fastcgi-cache URL: http://rtcamp.com/wordpress-nginx/tutorials/single-site/fastcgi-cache-with-purging/);
URL: http://www.cyberciti.biz recommendations used on this small project.
On this project, I need: - best practices (tutorial purpose, as it is a small project) - security (snort is missing at least, but security topic is not forgotten ) - reliability: high, efficiency: medium/high, scalability: low/high (cdn with AWS Cloudfront is missing)
