OpenDS and DSEE 7 Offer Compression

This week we have been sharing the different ways customer's can use compression to improve performance and reduce cost within your Directory Server Enterprise Edition environment.  On Wednesday, Brad Diggs, shared how customer's can use compression to reduce their storage footprint by 60%. Today, Ludo Poitou, Community Manager for OpenDS, wrote a great blog post on how to use compression in your OpenDS 2.2 instance.  Ludo shows how OpenDS can reduce the overall size of your directory instance.  He also gives pointers to how to configure in your directory environment.

Next week, Wajih Ahmed will be talking about how customer's can "Improving Import Speed Through ZFS Caching of LDIF import file".  He will show import rate of ds7 and opends with and without primary and secondary cache disabled vs. enabled.  This is another great example of the proven performance that Sun on Sun provides.

OpenDS in One Image

What is it like working on an open source project?  A lot of people wonder how does it differ.  The nightly builds, the open nature of communication and involvement, the external contributors and the community managers like Ludo Poitou make it a very dynamic environment.  The best way to understand it is to watch this great video that Ludo put together that represents the last three years of activity.  

Thanks Ludo:

Gartner IAM and Ludo's Architect Zone Interview on OpenDS

The identity team was in London for the Gartner Identity Access Management conference last week which was a successful event.  We had the opportunity to meet and talk with some great customers and hear about the Thompson-Reuters implementation of OpenSSO and Directory Server Enterprise Edition serving 300,000 concurrent users with persistent cookies.  This implementation allows traders to get their Reuter's feed on their smartphone and their desktop without having to login twice.  This reduces transaction fees and keeps their business model in tact.  The OpenSSO team did some great engineering work to meet the performance and functional requirements for Thomson-Reuters.  We video-taped the presentation and should have that for your soon.

Also, Ludo Poitou was recently featured in an article on OpenDS in the Architect Zone or DZone.  He describes some of the exciting things happening in the community with MySQL and discusses how to embed OpenDS in applications.  This is a great jump-off point for customers getting started with deploying OpenDS as an identity repository for their application or infrastructure serving email, calendar or network infrastructure.  You can read the whole article here.

Identity Security Webinar Wednesday, Jan. 21: OpenSSO and OpenDS in One Powerful Solution

There is a great webinar being offered on Wednesday, Jan. 21 which you may have missed the announcement because of all the excitement about the Inauguration and Martin Luther King Holiday in the US.  Daniel Raskin, Product Line Manager OpenSSO, and Jamie Nelson, Director of Engineering for OpenSSO, will be talking about the current release as well as the plans for the next release of OpenSSO Express.  There are already 200 registrants and there is a cap at 250 so register now so you don't get left out!

The Directory crowd should be interested as well, because OpenDS is bundled with OpenSSO and is used as OpenSSO's policy store and can be leveraged as a user store as well.  Here are the details:

OpenDS--Open Source Improves Quality in Software Development

Gary Williams, a staff engineer and the QA lead of OpenDS, published a great article with Marina Sum on the topic of how working on an open source software project has improved quality in product development.  The process is without challenges which he outlines in the article as well.  However, he also gives great detail about the test harness that is used, the amount of automation and community involvement to address the challenges and get high quality product in community hands more frequently.  The full article is available on the Sun Developer Network here

These are the types of processes that quality open source projects do as a part of the project development process.  Indira Thangasamy, produced a similar article on how they approach QA within the OpenSSO project.  As companies evaluate other open source projects, especially in these challenging economic times where cost reduction provide stronger rational's to consider starting projects using open source software.  The quality approach of communities becomes an important differntiator as companies use open source in production and customer facing systems.

Here is a quick overview of the test harness used on OpenDS:

We use open-source, Java platform-based test tools, such as the following, not only to demonstrate our support for open source but also to ensure that they are accessible to everyone:

Here are a couple of other highlights:

  • Unit Testing and Automation:  "Testing starts in the programming phase with unit tests, which verify that the code works as intended and which must exist for all features. Today, we run 30,000 automated unit tests daily on different Java virtual machines. No code can be integrated without satisfying the precommit requirements."
  • Code coverage — With open-source EMMA, we find out the number of code lines, blocks, methods, and classes that are exposed by the unit and functional tests. Part of that information pinpoints the amount of the code tested as a percentage of the total, defining if we've met the quality criteria. We also define which areas of the code are not tested, called coverage holes, and create new tests to fill them.
  • Feature coverage — OpenDS delivers features that customers want, that is, customer requirements. Each feature is recorded as an issue in the Issue Tracker, a tool that monitors defects. This data tells us the state the features are in and their status: Ready for Test or Tested.
  • Documentation coverage — To ensure that the documentation is reviewed according to the test plan, we adopt a two-phase documentation review process: a technical review of the content followed by a formal QA review. Like the product features, the documentation is divided into categories—books, chapters, and sections—that are recorded in the Issue tracker. Through this coverage, we measure the percentage of the documentation reviewed over time and identify the reviewers and review status.
  • Defect rates — This is a traditional measure. The goal is to have no high-priority bugs open at release time. Our Bug Council constantly studies the defects and assesses the risks to customers. We also plot simple graph trends to gauge how well the project is converging.

Thanks to Gary and Marina for publishing this article and allowing the community to learn from your experience.

OpenDS Monthly Call Tuesday November 4th, 2008, 9am PST, 6pm CET, 5pm GMT.

There are great things happening in the OpenDS project.  Last week the team released a major update to the code.  The release also contained a great new console to manage schema, edit entries, etc.  I will blog more about this later in the week.  

Additionally, Ludo is having his monthly call this morning to go over the new release and discuss some upcoming feature's.  Hopefully, you can join the call.  Here are the details.

Dear OpenDS users and developers,

Please join us on the phone for the next OpenDS monthly public  
meeting, Tuesday November 4th, 2008, 9am PST, 6pm CET, 5pm GMT.

On the agenda for this month meeting, we will review the current  
status of OpenDS 1.1, do an update on the roadmap and will present in  
details the changes that being integrated in OpenDS to be able to
