HAProxy is a fine piece of software, and performed quite well for a while, but it quickly started having issues as we got more sites. The main issue was that Epio has at least two (and often more) hostname-matching rules for each app we host, and we have rather a large number of apps - numbering in the thousands at the time we're talking about, and more these days.

4. LVS: Ipvsadm and Schedulers ipvsadm is the user code interface to LVS. The scheduler is the part of the ipvs kernel code which decides which realserver will get the next new connection.

In this post we are going to use Puppet in order to install and configure a WebLogic Server environment. This environment will consist of a WebLogic cluster that spans two (or more) machines, and includes Java Messaging and data source resources (the Java Messaging and data source resources are needed for the application that will be used to test the set-up). In order to install and configure a WebLogic environment, we create five modules wls_repo - defines the used variables, and contains files and templates. wls_install - installs the Java Virtual Machine and WebLogic. wls_basic_config - creates a basic domain (with an Admin Server) and sets-up the Node Manager on the machine where the Admin Server is running. wls_deploy_config - creates the deployment environment, such as clusters, machines, managed servers, messaging resources etcetera.

All your MySQL servers have to be configured to perform Master-Master replication as load balancing involves both reading and writing to all the backends. The following three droplets will be used in this article:

RequestReduce brings immediate Yslow and Google Page Speed score improvements not to mention a faster site! Since March I have been working in my “free” time on a framework to reduce the number and size of HTTP requests incurred from loading a web page. In short it merges and minifies css and javascript on your page and automatically sprites and optimizes css background images. All this is done on the fly (with caching) with no code changes or configuration required. G1 vs CMS vs Parallel GC This post is following up the experiment we ran exactly a year ago comparing the performance of different GC algorithms in real-life settings. We took the same experiment, expanded the tests to contain the G1 garbage collector and ran the tests on different platform. This year our tests were run with the following Garbage Collectors: -XX:+UseParallelOldGC-XX:+UseConcMarkSweepGC-XX:+UseG1GC Description of the environment The experiment was ran on out-of-the-box JIRA configuration.
