The most common software bundle is LAMP in the past.
What is LAMP? Linux + Apache + MySQL + PHP
How about LNMP? it is almost the same, except the change of the web server from Apache to Nginx. Why there is such change? Loading and performance issue.
Apache will consume a lot of memeory, if you are using just very low-end vps, your vps maybe down due to all memory are being used. we have bad experinece in the past for OpenVZ, the apache eat up all memory and the machine shutdown and need reboot.
In recent year, Nginx become more popular, few benchmarks make comparison between both, Nginx seems a lot better on load balancing and memory consumption.
One of the disadvantage is that you could not use .htaccess anymore. You have to re-learn the syntax of Nginx to adapt your needs.
