WANdisco's Distributed Coordination Engine (DConE) is the shared component for WANdisco clustering products. The DConE system allows multiple instances of the same application to operate on independent hardware without sharing any resources. All of the application servers are kept in synchronisation by DConE regardless of whether the servers are on the same LAN or globally separated and accessible only over a wide area network (WAN).
WANdisco's replication technology was the work of Yeturu Aahlad who had previously worked for Sun, Netscape and IBM and was involved in developing the CORBA Framework. Aahlad theorized a model for effective Active replication over a WAN. In the development of DConE, WANdisco has taken the Paxos algorithm as a baseline and added significant innovations relevant to mission-critical high, transaction volume distributed environments.
WANdisco provides replicated products for CVS, Apache Subversion, Git and Apache Hadoop. In addition support, consultancy and training services are offered. In 2011 WANdisco announced uberSVN, a deployment of Apache Subversion which included a web based management console and the ability to add additional application lifecycle management features. The uberSVN download was available through mid-2013.
WANdisco has three Apache Hadoop committers on staff: Konstantin Shvachko, Jagane Sundar and Konstantin Boudnik. In February 2013 WANdisco released a free distribution of Hadoop containing additional components developed by WANdisco.
WANdisco's involvement in the Apache Subversion open source project started in 2008 and they employ five contributors to work on the Subversion project with two working full-time. Namely Philip Martin, Julian Foad, Branko Čibej, Stefan Fuhrmann and Ben Reser, all of whom were Subversion contributors prior to working at WANdisco.
WANdisco also runs an annual conference for the Apache Subversion community, SVN Live, featuring core committers for the SVN project.
In December 2010, WANdisco announced its intention to develop some features for the Subversion project, specifically aimed at improving branching and merging functionality.
The Apache Foundation and some Subversion developers said the announcement contained unfounded claims and insinuations about community involvement and the lack of development on these features. According to Apache, these features were already being worked on at the time. David Richards from WANdisco clarified this position to the Subversion community and followed up by announcing WANdisco's sponsorship and ongoing support for the work of the Apache Software Foundation.
Apache Bloodhound is a software development collaboration tool, based on the Trac project. It includes an Apache Subversion repository browser, wiki, and defect tracker. In addition to the standard Trac installation, Bloodhound incorporates a number of popular modules into the core distribution, and includes additional improvements developed (as plugins) outside the Trac project. WANdisco maintains a staff of four full-time developers on this project.

There’s no simpler way to garner hate and come off like an ass than to say “everyone move aside and let me fix this”"
