Killer Java applications server with nginx and memcached | Francisco Souza. Last days I worked setting up a new web serving structure for Wine, the largest wine’s e-commerce in Latin America. After testing, studying and learning a lot, we built a nice solution based on nginx and memcached. I will use a picture to describe the architecture: As you can see, when a client do a request to the nginx server, it first checks on memcached if the response is already cached. If the response was not found on cache server, then nginx forward the request to Tomcat, which process the request, cache the response on memcached and returns it to nginx. Tomcat works only for the first client, and all other clients requesting the same resource will get the cached response on RAM. My objective with this post is to show how we built this architecture. nginx nginx was compiled following Linode instructions for nginx installation from source.
. % . After install nginx and create an init script for it, we can work on its settings for integration with Tomcat. Java application web.xml <? Jetty Continuations: Push Your Java Server Beyond Its Scalability Limits. With the phenomenal growth in Internet usage, a Web server's limited scalability often is a bottleneck when handling increased user loads. In fact, scalability is a necessity when business expansion results in more user interaction with your Web applications.
These applications include functions such as chat, collaboration, bidding, RSS broadcast, GPS, and real-time data. Two challenges in particular that current Web servers and applications encounter are the thread-per-connection concurrency model and asynchronous JavaScript and XML (Ajax). One solution for improving existing optimal throughput and scalability without adding resources is Jetty Continuations. Jetty Continuations suspend an HTTP request and releases the thread to the thread pool.
While Continuations is an obvious solution for such applications, they are also complex to implement. In this article, I will present a use case that explains how to use the Continuations API.

We’re all familiar with the Apache server and many of us have used Lighthttpd and Nginx and maybe some others too. So what makes Mongrel special? It’s language agnostic. It doesn’t have a PHP module, it doesn’t have a Python module, and yet you can still use those languages (and plenty more) with it, with very little effort to integrate new languages. Simplified overview of mongrel’s architecture When serving a PHP application, a server like Apache processes the HTTP request and then invokes some module – mod_php in PHP’s case – which then processes the scripting language in question and so on. Mongrel? How does it do anything useful then, you ask? So the HTTP request comes to Mongrel, which then processes it and converts it into a sensible format containing the vital info (headers, parameters, etc., in JSON) and gives it to ZeroMQ.
