Here’s an interview I gave with Business Computing World (http://www.businesscomputingworld.co.uk/qa-david-richard-wandisco/)
Can you position SCM and SCCM technologies as you see them in relation to ALM in the wider sense?
WANdisco’s heritage is in distributed computing—our technology enables active-active replication over a wide area network. The first application we implemented this with was Apache Subversion to create Subversion MultiSite (a distributed, highly available and scalable Subversion implementation).
Over the past couple of years we have become a very active participant on the Apache Subversion open source project and we are keen to ensure that Apache Subversion maintains its position as what we consider to be the world’s leading SCM tool.
Recently we announced uberSVN an open ALM platform for Subversion. The uberSVN platform is a very easy to use, easy to implement and easy to extend inside a distribution of Subversion. We see SCM as a core component of ALM—it’s where the source code files are stored. So transforming Subversion into a platform that enables you to choose best-of-breed ALM components is a very natural and evolutionary step for us. We don’t believe that any single vendor can provide a complete, best-of-breed ALM solution.
Why would a firm choose Subversion over traditional SCM solutions such as Perforce, Serena or even products from HP?
I guess a better question would be “Why do firms choose or replace traditional SCM solutions with Subversion?” I guess this is because Subversion is open source and hence free, but it performs and scales in some of the most aggressive SCM environments on the planet where some of the traditional SCM products could not. Subversion now has over five millions implementations—how many do the traditional SCM’s have? Not even a fraction of that and that means Subversion must perform and scale in a huge amount of environments.
It sounds like WANdisco’s core technology could be applied across multiple applications. Are you looking at other areas?
Indeed our replication technology is generic and can be applied to other areas. Relational databases is one area we are investigating in our labs right now. Maybe next year we will be in a position to announce something more concrete around database replication/shared-nothing database clustering.
Is WANdisco actively supporting the development of Subversion?
WANdisco is a huge supporter of the Apache Subversion open source project in a number of tangible ways. We have dedicated committers on staff that we pay to only develop Subversion, we are a sponsor of the Apache software foundation and we produce Subversion binary downloads and make them freely available on our website. There was some controversy last year but that was ‘rabble-rousing’ by one of our competitors. The end result is that Subversion development on the open source project is very active again. There is a lot of energy on the project right now and that is good for the wider community.
Are there any clear trends in the SCM space?
Subversion is continuing to gain adoption in the enterprise and government organisations. That’s probably not entirely surprising given that, in product lifecycle parlance, Subversion is in maturity. As I said earlier it continues to replace traditional SCM solutions. I would also say that Microsoft’s Team Foundation Server (TFS) is also gaining traction and is probably in the number two position. We don’t see enterprises moving their source code to the cloud yet. That may change but we have see some of the tooling move there—just not the source code.
What’s the uptake been like for uberSVN?
I’d say things are looking healthy, we have thousands of installs in just over a month and the feedback has been very good. I have never seen so many product installs and that is a good sign that the product is very easy to install. We worked very hard to get a product that could be installed in less than five minutes and we will never trade that off for anything.
Are there any big announcements scheduled for uberSVN?
In July we are planning a major new product feature that will enable customers to very easily install third party applications. It’s a really cool feature that will change the way ALM software is delivered behind the firewall. We also have some partner announcements around software build and quality tools.
Is GIT a threat to Subversion?
Funny, I was talking about this only today with an industry analyst and he has the same conclusion that we have. Git has its uses but probably not in the enterprise. OK please listen, I know that statement will upset a bunch of senior developers who think that GIT solves everything but it really doesn’t.
If you think about it GIT actually promotes anti-social software development; development in small, disconnected silos is not how software is developed in the real world. Most software is developed by teams whose members have a variety of skills who need to see what each other is doing and that’s the fundamental reason why GIT is not a threat to Subversion in the enterprise. It’s fine for the development of the Linux kernel but that model doesn’t work for most companies.
