WANdisco’s January Roundup

Happy new year from WANdisco!

This month we have plenty of news related to our move into the exciting world of Apache Hadoop. Not only did another veteran Hadoop developer join our ever-expanding team of experts, but we announced a partnership with Cloudera, and WANdisco CEO David Richards and Vice President of Big Data Jagane Sundar met with Wikibon’s lead analyst for an in-depth discussion on active-active big data deployments.

You may have heard that AltoStor founders and core Apache Hadoop creators, Dr. Konstantin Shvachko and Jagane Sundar joined WANdisco last year. Now we’re excited to announce that another veteran Hadoop developer has joined our Big Data team. Dr Konstantin Boudnik is the founder of Apache BigTop and was a member of the original Hadoop development team. Dr. Boudnik will act as WANdisco’s Director of Big Data Distribution, leading WANdisco’s Big Data team in the rollout of certified Hadoop binaries and graphical user interface. Dr. Boudnik will ensure quality control and stability of the Hadoop open source code.

In building our Big Data team, we’ve been seeking Hadoop visionaries and authorities who demonstrate leadership and originality,” said David Richards, CEO of WANdisco. “Konstantin Boudnik clearly fits that description, and we’re honored that he’s chosen to join our team. He brings great professionalism and distribution expertise to WANdisco.”

Also on the Big Data-front, CEO David Richards, and Vice President of Big Data Jagane Sundar, spoke to Wikibon’s lead analyst about our upcoming solution for active-active big data deployments.

We can take our secret sauce, which is this patented active-active replication algorithm, and apply it to Hadoop to make it bullet-proof for enterprise deployments,” said David Richards. “We have something coming out called the Non-Stop NameNode … that will ensure that Hadoop stays up 100% of the time, guaranteed.”

Watch the ‘WANdisco Hardening Hadoop for the Enterprise’ video in full, or read Wikibon’s Lead Big Data Analyst Jeff Kelly’s post about the upcoming Non-Stop NameNode.

Capping off our Big Data announcements, WANdisco is now an authorized member of the Cloudera Connect Partner Program. This program focuses on accelerating the innovative use of Apache Hadoop for a range of business applications.

We are pleased to welcome WANdisco into the Cloudera Connect network of valued service and solution providers for Apache Hadoop and look forward to working together to bring the power of Big Data to more enterprises,” said Tim Stevens, Vice President of Business and Corporate Development at Cloudera. “As a trusted partner, we will equip WANdisco with the tools and resources necessary to support, manage and innovate with Apache Hadoop-based solutions.”

As a member of Cloudera Connect, we are proud to add Cloudera’s extensive tools, use case insight and resources to the expertise of our core Hadoop committers.

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.”

WANdisco’s December Roundup

2012 has been an amazing year for WANdisco, but we still had a few more announcements for you this month, including news that we are extending our suite of service and support offerings to include the Git distributed version control system.

“Expanding our support offering to include Git is an obvious step to enable you to deploy and support the trending as well as the leading SCM tools,” said James Creasy, WANdisco’s Senior Director of Product Management in his ‘Supporting Git to Support You’ blog.

Our Git support includes:

  • Guaranteed response times
  • Availability 24 hours a day, 7 days a week
  • Contact via email or toll-free telephone

Git support is available immediately, please contact sales@wandisco.com for more information.

This news comes hot on the heels of our Big Data and Apache Hadoop announcements last month. WANdisco CEO, David Richards, and core creators of Apache Hadoop Dr. Konstantin Shvachko and Jagane Sundar recently conducted a webinar that covered how WANdisco sees the future of big data, following our acquisition of AltoStor.

This 30 minute webinar discussed:

  • The cross-industry growth of Hadoop in the enterprise.
  • How Hadoop’s limitations, including HDFS’s single-point of failure, are impacting the productivity of the enterprise.
  • How WANdisco’s replication technology will alleviate these issues by adding high-availability, data replication and data security to Hadoop.

If you missed out on the webinar, you can still find out all about WANdisco, Hadoop and Big Data by checking out the webinar slides on SlideShare.

The Subversion community also found the time for one more release before the holiday season. Subversion 1.7.8 features plenty of fixes and enhancements, including:

  • Adding missing attributes to “svn log -v –xml” output
  • Fixing a hang that could occur during error processing
  • Fixing incorrect status returned by 1.6 API
  • Adding Vary: header to GET responses to improve cacheability
  • Subversion 1.7.8 ignores file externals with mergeinfo when merging

A full list of everything that’s new in Subversion 1.7.8 is available at the Changes file. Free binaries of Subversion 1.7.8 are available to download through the WANdisco website. Users of SmartSVN, the popular cross-platform client for Subversion can also grab an update: SmartSVN 7.5.3 features plenty of improvements and bug fixes, including:

  • Refresh option to ask for master password, if required
  • Support launching on Solaris
  • Fix for an internal error that could occur after removing Tag
  • Special characters (e.g ‘:’) no longer cause problems in URLs

More information on the latest changes, is available at the SmartSVN changelog. If you haven’t tried SmartSVN yet, remember you can claim your 30 day free trial of SmartSVN Professional by visiting www.smartsvn.com/download

There’s been plenty of new content at the blog this month, including the first blog from Hadoop core creator Jagane Sundar, WANdisco’s new Vice President of Engineering of Big Data.

In his ‘Design of the Hadoop HDFS NameNode: Part 1 – Request processing’ post, Jagane demonstrates how a client RPC request to the Hadoop HDFS NameNode flows through the NameNode.

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.

We have plenty of exciting announcements planned for 2013, but for now we’d just like to thank everyone who has used our products, joined us for a webinar, eTraining or enterprise training session, picked us for your support needs, or provided the crucial feedback we need to make our products and services even better. And, of course, we’d like to wish you a very happy holidays from the WANdisco Team.

 

 

Answers to questions from the Webinar of Dec 11, 2012

 Download the webinar slides here.

Question 1: Are there any special considerations or support of Spring technologies for this (i.e. Spring-Data, Spring-Integration, Spring-Batch)?

Answer: We are continuously looking at technologies that make Hadoop easier to use and program. Spring-Data, Spring-Integration and Spring-Batch show promise. When sufficient momentum is gathered by these projects, we will work with the Spring community to include a tested version of these technologies in the AltoStor Appliance.

Question 2: What is the hadoop version underneath the appliance?

Answer: Hadoop 2. We intend to remain close to the latest version of Hadoop at any given point in time, modulo fixes and changes for bug fixes.

Question 3: Will the pricing model based on number of name nodes or size of the cluster?

Answer: Pricing decisions have not been made yet. We will announce pricing in the first quarter of 2013.

Question 4: Can you comment on how load balancing is resolved across active nodes? Is there a load balance router concept?

Answer: We do not require/depend on any specialized hardware such as load balancers or NFS filers. By “load balancing” we simply mean that application requests (read or write) can be directed to any NameNode based on its proximity to the client or available resources. Thus NameNodes can share the workload and provide higher overall cluster performance compared to active-standby architecture.

Question 5: How does Active-Active replication impact processing time relative to current Hadoop architectures?

Answer: Active-Active replication will result in load balancing of clients across many NameNodes, i.e. fewer clients will be serviced by each NameNode. Since NameNodes share the workload on a busy cluster, you should expect faster response time for clients. Generally, more active NameNodes can perform a proportionally larger amount of work.

About Jagane Sundar

WANdisco’s November Roundup

November has seen several big WANdisco announcements: an acquisition, a patent approval, and two prestigious industry awards. Not content with that, we also brought you our usual mix of software updates, community polls and training programs.

First up, we announced our acquisition of AltoStor, a pioneering firm with deep expertise in the Big Data market.

“The AltoStor acquisition will enable WANdisco to launch products quickly into the highly-lucrative Big Data market,” said WANdisco Chairman and CEO David Richards. “Combining our patented technology with AltoStor’s Big Data platform will provide us with a significant competitive advantage and provide organizations with a more reliable approach for managing big data.”

AltoStor founders Dr. Konstantin Shvachko and Jagane Sundar, who were among the core Apache Hadoop creators, will also be joining the WANdisco team as Chief Architect of Big Data, and Chief Technology Officer and Vice President of Engineering. Welcome to the team!

If you’d like to find out more about Apache Hadoop, Big Data, and how we’ll be applying our own  active-active replication technology to these areas, we’ll be holding a webinar on Tuesday, December 11th at 10am PST (1pm EST.)

WANdisco and Hadoop: The Future of Big Data for the Enterprise’ will  be conducted by David Richards, Dr. Konstantin Shvachko and Jagane Sundar.

This 30 minute webinar will cover:

  • The staggering cross-industry growth of Hadoop in the enterprise.
  • How Hadoop’s limitations, including HDFS’s single-point of failure, are impacting productivity.
  • How WANdisco’s active-active replication technology will alleviate these issues by adding high-availability to Hadoop, taking a fundamentally different approach to Big Data.

It’s free to attend, but places are limited so register now to avoid disappointment.

If you’ve ever taken a look at our enterprise Subversion products (such as MultiSite, the unique replication, mirroring and clustering solution) you’ll already be familiar with our core replication technology. We have now been awarded a US ‘Distributed computing systems and system components thereof’ patent that covers this technology. The patent states that “unlike conventional solutions, the multi-site computing system architecture does not rely on a central transaction coordinator that is known to be a single-point-of-failure.”

“”I am delighted the USPTO has allowed WANdisco’s patent, which we believe to be a breakthrough in the field of data replication,” said David Richards “This patent validates our leadership in distributed computing and our belief that no other company can achieve active-active replication over a Wide Area Network.”

Remember, that if you want to try this unique, patented technology for yourselves, you can currently claim a free 15 day trial of Subversion MultiSite.

Continuing with the enterprise announcements, we launched a new enterprise-class, on-demand Subversion training program. We know it’s not always easy to set aside time for enterprise training, so we’ve made it even easier to get the training you need to get the most out of Subversion.

Designed with the enterprise in mind, our step-by-step video modules cover all the crucial SVN topics, including:

  • Basic Operations and Command Line
  • Handling Merge Conflicts
  • Advanced Repository Management
  • SVN Changelists
  • Hook Scripts

Sign up before December 15th, to claim one month of Subversion eTraining for free, with a 6 month agreement, or 3 months free with a 12 month agreement. You can view the complete course list online, or request a quote.

The Apache Bloodhound team recently announced the first release of this new project, and now we’re pleased to see that the second release of Apache Bloodhound has arrived. Apache Bloodhound 0.2 (Incubating) upgrades to Bootstrap version 2.1, and fixes various issues from the 0.1 release, alongside various bug fixes relating to the new user interface.

Although WANdisco are sponsoring some of the initial committers, one of the Apache Bloodhound project’s core goals is to create a strong developer community around the Trac code base in a vendor-neutral location. If you’re interested in participating in the Apache Bloodhound project, you can learn more at the ‘Getting Involved With Apache Bloodhound’ page.

We were also pleased to announce the release of SmartSVN 7.5. SmartSVN 7.5 is a major step forward for the client, bringing the following benefits to the SmartSVN community:

Streamlined and Simplified, A Better UX

  •  New GUI library (SWT) to provide native look and improved responsiveness
  • A clean and compact branching structure view with an Enhanced Revision Graph
  • See file statuses at a glance
  • No longer forced to create a repository profile (profiles can still be used if preferred)

Little Things, Made Easier

  • Edit properties directly in the Repository Browser
  • Export smaller HTML graphic files with the Export option of Revision Graph
  • Remove, Move, and Copy now operate on multiple selected directories
  • Default, unchanged files are not shown. (To find files, use the File Filter)

More Secure

  • The freedom to work offline. When offline, the remote state and transactions are not refreshed automatically – Log and Revision Graph operate from data already stored in the log cache
  • Support for safe password storage with the Plugin-API

Not yet tried SmartSVN? You can claim your 30 day free trial of SmartSVN Professional now.

If you’re a SmartSVN user – or someone interested in getting started with this popular, cross-platform client – we need your input to design our new SmartSVN eTraining modules.

What topics would you like to see in these sessions? Please take a moment to complete our quick poll on what you’d like us to cover in SmartSVN eTraining. Or, if you’d like to see a subject that’s not listed in the poll, please feel free to Contact Us directly.

The first award was presented at the techMark 2012 awards dinner in London in the Emerging Star category, and the second award was at the Shares Awards 2012, in the Best IPO category.

“Our readers who vote for the Shares Award in the Best Initial Public Offering/Fund Raising of the Year category clearly know a good market newcomer when they see one. Prior winners such as Wellstream, Kentz and Waterlogic all have a formidable pedigree and I am delighted to welcome WANdisco to this elite club of winners,” says Russ Mould, editor of Shares Magazine.

WANdisco and Hadoop: Future of Big Data for the Enterprise

You may have already heard that WANdisco has acquired AltoStor, and welcomed AltoStor founders and core creators of Apache Hadoop, Dr. Konstantin Shvachko and Jagane Sundar to the WANdisco team.

“I believe that the combination of AltoStor’s expertise and WANdisco’s patented active-active replication technology is the proverbial marriage-made-in-heaven,” said WANdisco co-founder and chairman, David Richards. “The AltoStor acquisition will enable us to launch products into the highly lucrative Big Data / Hadoop market early next year.”

Want to learn more about Apache Hadoop, Big Data, and how we’ll be applying our own  active-active replication technology to these areas? Join us on Tuesday, December 11th at 10am PST (1pm EST) for a 30 minute webinar that will deep dive into all these topics.

WANdisco and Hadoop: The Future of Big Data for the Enterprise’ will be conducted by David Richards, and Dr. Konstantin Shvachko and Jagane Sundar, who have joined WANdisco as Chief Architect of Big Data, and Chief Technology Officer and Vice President of Engineering for Big Data, respectively.

This 30 minute webinar will cover:

  • The staggering, cross-industry growth of Hadoop in the enterprise.
  • How Hadoop’s limitations, including HDFS’s single-point of failure, are impacting the productivity of the enterprise.

We Just Acquired Big Data / Hadoop Company AltoStor.

I believe that the combination of AltoStor’s expertise and WANdisco’s patented active-active replication technology is the proverbial ‘marriage-made-in-heaven’.  The AltoStor acquisition will enable us to launch products into the highly lucrative Big Data / Hadoop market early next year.

So how lucrative is this market?  Well, I recently read an interesting article in Wikibon “Big Data: Hadoop, Business Analytics and Beyond” that Big data / hadoop market sizereiterated what we already knew.  Big Data isn’t a might happen next year thing.  No, it’s here today, to steal a quote from the excellent article: “Make no mistake: Big Data is the new definitive source of competitive advantage across all industries. Enterprises and technology vendors that dismiss Big Data as a passing fad do so at their peril and, in our opinion, will soon find themselves struggling to keep up with more forward-thinking rivals…. For those organizations that understand and embrace the new reality of Big Data, the possibilities for new innovation, improved agility, and increased profitability are nearly endless.”

So why did we acquire AltoStor?

First off, the founders (Dr. Konstantin Shvachko and Jagane Sundar) are really good guys.  This was an ‘old-school’ acquisition.  An initial deal was struck very quickly with a handshake.  Both sides could see very clear value – so doing the deal was incredibly simple.  I love the fact that they wanted stock as consideration – that’s real proof that they see significant long term-value creation rather than short-term gain.

For WANdisco Big Data is a Big Market.  We can see clear synergy between our unique / patented active-active replication technology and the hadoop logocreation of Hadoop high availability (HA) solutions.  This is one of the reasons why AltoStor was so attractive to us.  They have unique knowledge in the space:

•            The AltoStor founders have been working on Hadoop since its inception in 2006 at Yahoo.  Konstantin was part of Doug Cuttings team that created and implemented Hadoop.  His focus was massive scale, performance and availability of Hadoop – developing the Hadoop Distributed File System (HDFS).  He then went on to eBay where he implemented Hadoop.

•            The Founders are intimately aware of the problem WANdisco is planning to solve around Hadoop HA and hence understand the value of the solution in large scale Big Data replication over a Wide Area Network.

•            Finally, AltoStor are developing a product that is slated for release in Q1 2013, that will significantly simplify deployment of Hadoop / Big Data for enterprises.

Following the acquisition we now expect to have products available in the first quarter of 2013.  That’s very good news.

There’s going to be a lot of noise in this space over the coming months and years.  Many will jump on the ‘bandwagon’, making all sorts of lavish claims to be ‘the big data this’ and ‘the big data that’.  It always happens in hype-cycles like this.  In reality most are just companies repurposing existing legacy products and slapping a new label on it.  This is NOT one of those.  We are building from the ground-up with unique knowledge and information that only a few in the world have (the amount of brain-power in the room during some of the early design meeting was frightening!)

In 2005 when we founded WANdisco my peers would tell me that active-active replication over a Wide Area Network was impossible.  Well we’ve got hundreds-of-thousands of users using the technology for core development every day.  Applying this technology to Hadoop is groundbreaking and I think it will change the way the industry views network storage.  We like making the impossible possible at WANdisco.
