On the Subversion side of things, the SVN community announced their first release of 2013, with an update to the Subversion 1.6 series.

Apache Subversion 1.6.20 includes some useful fixes for 1.6.x users:

  • Vary: header added to GET responses
  • Fix fs_fs to cleanup after failed rep transmission.
  • A fix for an assert with SVNAutoVersioning in mod_dav_svn

Full details on Apache Subversion 1.6.20 can be found in the Changes file. As always, the latest, certified binaries can be downloaded for free from our website, along with the latest release of the Subversion 1.7 series.

How many developers can a single Apache Subversion server support? In his recent blog post, James Creasy discussed how DConE replication technology can support Subversion deployments of 20,000 or more developers.

“While impressive, DConE is not magic,” writes James. “What DConE delivers is a completely fault tolerant, mathematically ideal coordination engine for performing WAN connected replication.”

In another new DConeE post, James explains where DConE fits into the ‘software engineering vs. computer science’ debate, and warns “in the world of distributed computing, you’d better come armed with deep knowledge of the science.”

Finally, WANdisco China, a Wholly Foreign Owned Enterprise was announced this month, following WANdisco’s first deal in China with major telecommunications equipment company Huawei. From this new office we’ll be providing sales, training, consulting and 24/7 customer support for WANdisco software solutions sold in China, and are excited to be expanding our activities within this region.

We view China as an emerging and high growth market for WANdisco,” said David Richards. “It was a natural progression to establish our Chengdu office as a WFOE and ramp up staff there as so many companies have operations in the country. We are excited about this announcement and look forward to the growth opportunities this brings.”

When you think of “the cloud”, what comes to mind? In his first WANdisco blog, Director of Product Management James Creasy takes a fresh look at one of IT’s biggest buzzwords. He argues that most of the applications used by enterprises were not originally architected for cloud infrastructures, and looks at how this problem could be overcome by “putting the cloud into a virtual eyedropper.” In his second blog, ‘Planned Downtime Is Still Downtime’ James argues that planned outages of critical applications aren’t inevitable:

Through the 20th century and into the 21st we’ve gritted our teeth against this inescapable cost. We’ve built massive failover servers, concocted elaborate master/slave replication schemes, and built businesses around High Availability and Disaster Recovery scenarios (HADR). We thought we were doing the best we can.

And we were, until recently.”

You can read the ‘Planned Downtime is Still Downtime’ post in full at the WANdisco blog.

We also had some new team photos taken by our friend and neighbour at our Electric Works offices, Matt Lollar. We even managed to get some shots outside in the Sheffield sunshine.

Putting The Cloud Into An Eyedropper

When you think of “the cloud”, what comes to mind? For some, it’s racks and racks of commodity hardware. Others may consider the benefits of dynamic scalability or worldwide availability.

There’s another side to the cloud on my mind, which is that many, and likely most, of the applications that enterprises use to run their business were not architected for cloud infrastructures. For example, SCM tools like Subversion, Perforce, and others eye an uneasy life in the cloud. Ten or more years ago, IT environments often centered around bare metal deploys of “big iron” servers. Lights flashed and cables snaked around massive refrigerated server farms.

Fast forward to today’s young high and not-so-high tech firms. On my first day at WANdisco, I found myself standing in the kitchen, wondering where the server room was. Turns out, I was looking at it: a few small boxes tacked up on the wall near the paper towels. Of course! Today’s companies have outsourced many previously in-house applications to cloud based services such as Gmail, Google Docs, Salesforce.com, WorkDay, and many more.

Legacy applications, often used to the high processor speeds, large amounts of RAM, and RamSans of traditional vertically scaled environments, are often fish-out-of-water in a typical horizontally-scaling, public cloud environments such as Amazon EC2.

The solution moving forward has to be grueling, ground-up rewrites of these applications for the multi-machine, multi-master environment of today’s cloud.

Or does it?

While learning about WANdisco’s patented replication technology and implementation called DConE, it occurred to me that it brings many of the benefits of the cloud to existing applications. DConE has effectively condensed many of the benefits of the cloud into a virtual eyedropper, where it can easily be dripped onto almost any existing database application.

For example, it converts a centralized, vanilla Subversion repository into a multi-machine, multi-master, robust replication group with no single point of failure. It adds scalability by easily configuring read-only nodes. HADR (High Availability Disaster Recovery) is built in: if a node loses connectivity, the others transparently take over the load. In many cases, users will not even be aware of a problem. When the previously isolated node comes back on line, it silently catches up with the others.

Importantly, DConE can easily and quickly be integrated with new applications. It’s not the cloud as most think of it, but could it be considered a form of virtualization that delivers some of the promise of the cloud to essential applications?

What applications are you dependent on that could benefit from cloudlike capabilities of HADR, global multi-site, and horizontal scalability? We’d love to hear about them.
