Technology / Patents
WANdisco s Distributed Coordination Engine (DConE) is the shared component that powers all 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 WAN. This is achieved by replicating changes made against one server to the others in real-time (Active replication).
WANdisco's replication technology was the work of Dr Yeturu Aahlad who had previously worked for Sun, Netscape and IBM and was heavily involved in developing the CORBA Framework. Dr Aahlad theorized a model for effective Active replication over a WAN.
WANdisco provides a range of clustering products for CVS and Apache Subversion as well as Subversion support and consultancy services. In 2011 WANdisco launched uberSVN, a deployment of Apache Subversion which includes a web based management console and the ability to add additional ALM features easily.
The company's website lists various Fortune Global 1000 companies such as AT&T, APC, Avaya, Bally Technologies, Thales Group, Verisign, Sun Microsystems, Honda, NTT, Intel, John Deere, Disney, Symantec, Barclays, Merrill Lynch and Motorola.
Open Source Contribution
In October 2009, WANdisco provided funding for three full time Open Source contributors to work on the Subversion project. One of the contributors, Hyrum Wright was also appointed as WANdisco s Director of Open Source, where he remained until June 2012. The other contributors are Philip Martin who had been a core Subversion contributor for the previous 8 years and was part of the original Subversion development team, and Julian Foad who had been a core Subversion contributor since 2003. In July 2012 the open-source contingent increased when Branko ibej, a Subversion contributor since May 2000, and Stefan Fuhrmann, a contributor to TortoiseSVN since 2003 and Subversion since 2010, joined the company .
WANdisco also runs an annual conference for the Apache Subversion community, SVN Live, featuring core committers for the SVN project.
Subversion Server Binaries
WANdisco currently provides Apache Subversion binary downloads for Windows, Debian, CentOS, Solaris (operating system), Ubuntu (operating system) and RHEL via its website. These binaries have been through a complete testing cycle and use the default package management system for each Linux distribution.
On April 22nd 2011 WANdisco launched uberSVN, a package containing Apache Subversion and all its dependencies with an easy to use installer and web based management interface. The goal of uberSVN is to provide "an open extensible platform for application lifecycle management (ALM) that's easy to install, easy to use and easy to extend."
There's also an integrated uberAPPS store, including apps such as Jenkins, uTest and uberSVN Access Control.
uberSVN officially came out of beta in April 2012, with the Chimney House release. Releases are named after various Sheffield venues.
Subversion project announcements
In December 2010, WANdisco announced their intention to undertake major work on the Apache Subversion project, specifically aimed at improving branching and merging functionality. These changes had been proposed by the community previously but there had been no activity towards implementing them. WANdisco stated that demand from their enterprise customers had led to the decision to commit resources in this area.
Some perceived the timing and manner of the announcement to be controversial and at odds with the Apache Software Foundation's position as leaders of the Subversion project. David Richards from WANdisco clarified this position stating that he in no way wished to undermine the Apache 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 a 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.
