BIE (Business Integration Engine) is an open source integration system that makes it easy for organizations to exchange data with external trading partners regardless of their native applications. It competes in the same space as applications like Microsoft BizTalk except that it is truly cross-platform since it written in Java.
MultiLoad is a load balancer that redirects HTTP requests to pre-defined servers/locations. It gives the provider a way to balance the traffic and hides the real download location. It allows you to manage different version of each download. It is also a load balancing server extension. You can distribute files on some servers so that a downloaded file can be loaded form different servers. These servers can have different priorities to control the active traffic.
Proto Balance is a load balancing and traffic management system that can handle up to 10,000 concurrent connections and 20,000 downloads per second. Proto Balance is a load balancer and TCP traffic port forwarder for high availability. It features an easy-to-use Web interface that requires minimal knowledge of networking and no command-line experience. Its target audience includes enterprise cluster providers, Internet service providers, and network administrators.
Sharedance is a high-performance server that centralizes ephemeral key/data pairs on remote hosts, without the overhead and the complexity of an SQL database. It was mainly designed to share caches and sessions between load- balanced PHP Web servers. Access to a Sharedance server is trivial through a simple PHP API and it is compatible with the expectations of PHP 4 and PHP 5 session handlers with no code change.
kds (krico's distributed storage) is a distributed storage system. Its main goal is to work as a session handler for PHP. This package provides four components: a daemon (kdsd), a command-line cilent (kdsc), a library (libkds), and a PHP session handler extension. kdsd is a daemon that uses worker threads to process KDSPROTO requests. It then retreives or stores data in a BerkeleyDB storage. A nice little curses program is also supplied to monitor the storage state.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
