DVCS git is trending fast in software development futures


RedMonkRedMonk recently posted on Centralized vs Decentralized Version Control: 2010 vs 2012. They mentioned that the inquiries regarding decentralized or distributed version control (DVCS) technologies, such as git, has spiked. RedMonk went on to add that some organizations are considering migrations to such technologies, while others have committed to the move in general, but require data to justify their decisions internally.

gitWe recently covered a tool in this space for the Atlassian community (see Atlassian Stash Powers Enterprise Application Developers with DVCS Git). Stash incorporates the latest and greatest technologies in DVCS source code management and git, allowing you to create and manage repositories, set up fine-grained permissions, and collaborate on code in a secure, fast and enterprise-grade manner. It was released in the Spring of 2012.

In the RedMonk post, they looked at the question of DVCS usage via Ohloh over the past two years. The two most obvious changes from 2010 to 2012 are the decline in CVCS traction (centralized) and the growth of git (decentralized). git’s share, in particular, almost tripled in two years, while CVCS declined by better than 50%.

They also presented at chart of the leading repositories. Each decentralized repository, including git, demonstrated growth while the two centralized systems, CVS and Subversion, declined. Second, git substantially outperformed both Bazaar and Mercurial from a growth perspective.

It seems that developers are voting for decentralized git repositories with their feet, or perhaps their keyboard/mouse.

RedMonk showed further data that indicates there is still room for more growth for git. If you look at the absolute numbers, rather than growth, centralized repositories are still in the lead. Their data show that while nearly a third of all projects are now employing DVCS, versus 14% two years ago, almost 70% of projects remain in centralized version control (CVCS).

RedMonk concludes the git is the clear winner over the past few years.

Stash - git repository managementIn line with this trend, Atlassian Stash – Atlassian’s behind the firewall git repository manager – is gaining good traction in the market, as can be expected. BitBucket, their SaaS DVCS offering (supporting both git and Mercurial) is also growing fast – both being yet more alignment to this growing trend.

Source Code Importer for Atlassian StashAppFusions, in further support of this trend, has recently released a Source Code Importer for Atlassian Stash, that is available at the Atlassian Marketplace now. This importer significantly decreases the challenge of migrating SVN to git for use with Stash.
