Suppose someone were to describe to you a website built using HTML5, CSS3, Ext JS and Node.js. It had PHP at the server side backed with a MongoDB database, all running off a HipHop server optimized by Varnish Cache. You might suspect that such a cocktail of web technologies is unnecessary to have a mere online presence.
After all, HTML, CSS and JavaScript on the client side and possibly a dynamic language should suffice. But as you start to build bigger, faster, more scalable and more highly optimized websites or applications, you’ll reach a roadblock.
