WANdisco is dual-headquartered in Sheffield, England and San Ramon, California.

History

The name WANdisco is an acronym for wide-area network distributed computing. WANdisco was co-founded in 2005 by David Richards and Dr. Yeturu Aahlad. They grew the company without raising any private equity, venture capital, or angel funding and led it to a successful IPO on the London Stock Exchange on June 1, 2012.

The company's initial offering — a replication solution for distributed teams using the Concurrent Versions System (CVS)— was expanded in 2006 to include Apache Subversion with SVN MultiSite Plus. In 2013 and 2014, Git with Git MultiSite and Gerrit with Gerrit MultiSite, respectively, were added.

In 2012, WANdisco acquired AltoStor and entered the big data market with its non-stop Hadoop product.[3] AltoStor's founders, Dr. Konstantin Shvachko and Jagane Sundar, joined WANdisco as part of the acquisition and helped develop WANdisco Fusion, the company's next-generation Hadoop product, which was released in 2015.

Today, WANdisco provides data migration products not only for CVS, Apache Subversion, Git, Gerrit, and Apache Hadoop but also Amazon Web Services, Microsoft Azure, Google Cloud Platform, and Oracle Cloud Infrastructure. In addition, the company offers support, consulting, and training services. WANdisco is also a corporate contributor to Hadoop, Apache Subversion, and other open source projects.

Technology and products

WANdisco's Distributed Coordination Engine (DConE) is the shared component for WANdisco clustering products.[4] DConE allows multiple instances of the same application to operate on independent hardware without sharing any resources. All of the application servers are kept in synchronization by DConE regardless of whether the servers are on the same local-area netowrk (LAN) or globally separated and accessible only over a wide-area network (WAN).

WANdisco's replication technology was the work of WANdisco co-founder Yeturu Aahlad, who had previously worked for Sun, Netscape and IBM, and was involved in developing the CORBA Framework.[5] 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 innovations relevant to mission-critical, high-volume transactions distributed environments.

WANdisco provides replication products for CVS, Apache Subversion, Git, Gerrit, Apache Hadoop, Amazon Web Services, Microsoft Azure, Google Cloud Platform. In addition, the company offers support, consultancy and training services.

IBM partnership

In April 2016, IBM signed a deal to become an original equipment manufacturer (OEM) for WANdisco Fusion.[6] The deal allows IBM to rebrand Fusion as "IBM Big Replicate" and plays an important role in the IBM big data and cloud computing strategy, including the movement of data between on-premises software and the cloud.[7]

Blockchain

In July 2018, WANdisco announced that it had filed a new patent in blockchain.[8] The company claims that the patent "...enables effective permissioned blockchain transactions with an underlying algorithmic mechanism. This mechanism enables throughput to be achieved that is orders of magnitude higher than public blockchains."

Discontinued products

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.[9] The uberSVN download was available through mid-2013.[10]

Open source contributions

In September 2013, WANdisco announced its official sponsorship of AMPLab, a five-year collaborative effort at the University of California, Berkeley.[11]

Hadoop

WANdisco has one Apache Hadoop committer on staff: Jagane Sundar. In February 2013, WANdisco released a free distribution of Hadoop containing additional components developed by WANdisco.[12]

Subversion

WANdisco was involved in the Apache Subversion open source project from 2008[13] to 2015, employing several contributors to work on the Subversion project during that time.[14]

Server and client binaries

WANdisco provides Subversion binary downloads for Windows, CentOS, Debian, Oracle Linux, RHEL, SUSE Linux, Ubuntu, Mac OSX, and Solaris through its website.[15] These binaries use the default package management system for each Linux distribution.

Project announcements

In December 2010, WANdisco announced its intention to develop features for the Subversion project,[16] specifically aimed at improving branching and merging functionalities. 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.[17] According to Apache, these features were already being worked on at the time.[13][18] WANdisco CEO David Richards clarified this position to the Subversion community[19] and followed up by announcing WANdisco's sponsorship and ongoing support for the work of the Apache Software Foundation.[20]

Share suspension

On March 9, 2023, the company's shares were suspended from trading in London, citing potentially fraudulent irregularities.[21] The company said it expected revenue for 2022 could be as low as $9 million compared to its previous expectation of $24 million.[21]
