SpringSource + VMware: My VMworld 2009 Interview

I had the chance to sit down with John Troyer to discuss SpringSource, VMware, cloud computing, and breaking down the barriers between Development and Operations...live (at the time) on the show floor at VMworld 2009.

VMware Fanboy

After arriving at SFO airport earlier this week, I just had to stop and snap the photo below:


The placement and timing of the ad was special since 1) I'm excited to be joining VMware as part of the SpringSource acquisition, and 2) I flew in to SFO in order to attend VMworld 2009 (the event was ginormously huge with lots of great sessions, excited attendees, and impressive partners).

I've been a fanboy of VMware for years: I've been an avid and happy user of VMware's products, and earlier this year I declared VMware the "Virtualization Big Dog" as part of my "Big Dog" series of posts.

In that post I compared VMware with Microsoft, Citrix, and Red Hat, and I concluded by saying "As long as VMware stays focused on creating great solutions to customer problems and honestly assesses the threats posed by the other market players, they should be able to retain their market leadership status for many years to come."

I love working for companies that provide REAL VALUE to customers, and I look forward to joining VMware as soon as the deal closes and extending its market leadership from virtualization to the cloud and beyond.

Multiple Languages, Multiple Platforms: Choice Is A Good Thing

Over the past decade or so, the Microsoft vs. Java landscape has been summed up as follows:
  • Microsoft: Multiple languages, single platform.
  • Java: Single language, multiple platforms.
In "Java yields to other languages on the Java Virtual Machine" Paul Krill from InfoWorld covers the fact that Java is no longer the only language in town when it comes to creating applications that run on the Java Virtual Machine.

Languages such as Groovy, JRuby, and Scala are just a handful of languages beyond Java available for the JVM.

The fact is that over the past few years the landscape has changed to be:
  • Microsoft: Multiple languages, single platform.
  • Java: Multiple languages, multiple platforms.
Why is offering a choice of languages important? Neil McAllister provides some good reasons in "We need more polyglot programmers". The emergence of other languages targeting the proven and scalable Java platform is a good thing for the Java market. It will help keep the Java platform vibrant and expand its market reach.

Neil makes the point that Groovy "offers a Java-like syntax but is actually a dynamic language, similar to Perl, Python, and Ruby. It gives developers the safety and stability of the Java runtime but frees them from the often-restrictive Java syntax.".

All of these points factored into why SpringSource added Groovy and Grails into our portfolio of product offerings.

Bottom-line: Choice of language and platform is a good thing...for developers, customers, software vendors, and the market in general.

Harry Kalas - Outta Here!

Philadelphia paid tribute today to Harry Kalas, the voice of the Philadelphia Phillies. Kalas passed away earlier this week and the fans filled Citizens Bank Park to pay their respects and to hear Harry Kalas' close friends and colleagues share their thoughts and feelings.

I think Mike Schmidt summed it up the best in his eulogy when he said that Harry Kalas' life was "bountiful".

I think we should all strive to lead "bountiful" lives.

While I've never met Harry Kalas, he has been a part of my life for many years. Thinking of him reminds me of my father who taught me to love baseball and the Phillies. My dad was my little league coach, and he came to watch me play baseball through high school, college, and even into my 30's when I played over-30 baseball with some of my old high school buddies.

I visited my dad's grave today to spend some time reminiscing with him about the great calls that Harry Kalas made over his broadcasting career, including:

"Long drive! It is....outta here!
Home run...Michael Jack Schmidt!"

We definitely heard that call many, many times.

Unfortunately my dad passed away before hearing one of Harry's best:

"The 0 - 2 pitch...swing and a miss...struck eem out!
The Philadelphia Phillies are 2008 World Champions of Baseball!!"

So long Harry. We'll miss you.
And if you get a chance, please say hi to my dad for me.

For those who weren't Phillies fans or for those who want to reminisce along with me, here's a handful of Harry's best calls:


And here's a nice tribute to Harry Kalas by Comcast:

Google App Engine Is Groovy Baby!

The SpringSource Groovy team and the Google App Engine Java team worked together to make sure that Groovy works on Google App Engine now that App Engine supports Java: "Seriously this time, the new language on App Engine: Java™"

Guillaume Laforge, of SpringSource, has a great post about how to "Write your Google App Engine applications in Groovy".

Check out some initial Groovy sample apps running on App Engine:
http://myowngroovy.appspot.com

Here you'll find the standard "Hello World" app, a Google Maps, Google Geocoding service, Flickr mashup application, and more.

10 Rules For Building A Great Organization

I'm reading "Enough. True Measures of Money, Business, and Life" by John C. Bogle, the founder and former CEO of Vanguard Mutual Fund Company. In the book, Bogle offers 10 Rules for Building a Great Organization:

  1. Make caring the soul of the organization.

  2. Forget about employees. (Vanguard instead uses the term "crew member")

  3. Set high standards and values - and stick to them.

  4. Talk the talk. Repeat the values endlessly.

  5. Walk the walk. Actions speak louder than words.

  6. Don't overmanage.

  7. Recognize individual achievement.

  8. A reminder - loyalty is a two-way street.

  9. Lead and manage for the long term.

  10. Press on, regardless.


A pretty solid set of rules if you ask me.

Job Trends: Tomcat, Spring, Weblogic, JBoss, EJB

Forrester recently described a trend that they refer to as "lean software" in their paper entitled Lean Software Is Agile, Fit-To-Purpose, And Efficient. They state that "lean software is emerging as the antidote to bloatware" and that "the trend toward lean software has been building for years, but the worldwide recession is accelerating it".

Forrester mentions SpringSource as one of four companies at the forefront of the lean software movement. This is due to our leadership within the Spring, Apache, Groovy and Grails communities, as well as our active encouragement, via SpringSource dm Server, of enterprise OSGi as the basis for next-generation application infrastructure.

Since Spring and Apache Tomcat play an important role in lean application infrastructure strategies, I've researched what the job market looks like for developers with Spring and Tomcat skills as compared to EJB, Weblogic, and JBoss skills.


I used Indeed.com to generate the chart above. Indeed.com searches millions of jobs from thousands of job sites and provides a neat service that lets you see job trends for whatever search criteria you may have.

My criteria was Java Developers that have Tomcat, Spring, Weblogic, JBoss, or EJB skills. Click here to go to Indeed.com to see the latest view of my chart above.

The chart nicely illustrates that Spring skills (green line) are in highest demand, well ahead of the others, and has been on a steep incline for the past year. Weblogic skills (blue line) are next and have remained fairly flat over the years. EJB skills (red line) and Tomcat skills (orange line) are neck and neck behind that, with JBoss skills (black line) tracking behind Tomcat but on a similar path.

NOTE: I've been asked why I did not include Glassfish, Geronimo, or WebSphere CE in the above chart. The reason is simple: they were effectively zero on the graph and therefore statistically irrelevant for my analysis.

UPDATED ON MARCH 30 2009:
Let me reiterate that the point of this post is to show that Spring and Tomcat Java developer skills are as easy to find in today's job market as other popular enterprise Java developer skills. With that said, I've been asked why I did not include WebSphere in the chart above. One could argue that WebSphere as a brand is broader than the other items in the search criteria, but I've modified the criteria to include it; the chart now covers Java Developers that have Tomcat, Spring, Weblogic, JBoss, EJB, or WebSphere skills.

Click here to go to Indeed.com to see the latest view of the chart above.

Conclusions?
More and more companies are looking at lean application infrastructure to help them remain competitive, and the difficult economy is only accelerating this trend. These businesses not only need to feel comfortable with the technologies they embrace, but they also need to make sure they can easily find people experienced with the technologies.

Since I work at SpringSource, I have a keen interest in the health and vibrancy of both Spring and Tomcat. I'm happy to see that Spring and Tomcat are doing so well in the job market for Java developers. This fact will help my customers feel more comfortable choosing SpringSource Enterprise and SpringSource tc Server to power their applications.

Credits: I'd like to thank Indeed.com for providing this valuable job trends service on their website. It provides a great way to understand the past and current directions of whatever type of job you may be interested in.

JVM as a Service: Mashup Azul and Amazon

This may be a crazy stupid idea, but I was having a conversation today about the kinds of things that make sense to be "as a service". Amazon EC2 and S3 are essentially compute as a service and storage as a service.

Since I'm a Java guy, I wonder:
Does it make sense to have a JVM as a service?

Why? Because while running Java workloads on Amazon may be cool for scale out scenarios, it does nothing to help with scale up scenarios for Java workloads. The classic JVM is a limiting factor in scale up scenarios because the more memory it has to deal with the more garbage collection time becomes a real performance issue.

Azul Systems offers a JVM compute appliance that illustrates the logical model of what I have in mind. Basically the Azul appliance centralizes JVM processing onto a machine designed to provide low response times, pauseless garbage collection, and efficient huge memory management. Basically each server has a JVM proxy that hands off processing to the compute appliance.

So, what if we mashup Azul with Amazon?

That is, what if we take the Azul JVM appliance concept and make it a cloud service? That could enable any EC2 instance running a Java workload to leverage a model where a JVM proxy on a given EC2 instance hands off its processing to a JVM as a Service. That JVM as a Service could then centrally handle dynamic scale up/scale down of JVM resources as well as eliminate the nasty garbage collection performance issues once and for all.

Now all we need is the JVM gurus at Azul or Oracle/BEA JRockit to get to work on it. I want my JVM as a Service guys, and I want it now!!! :-)

If you are a JVM guru, feel free to chime in as to why this idea is stupid and could never possibly work. Or if you have an equally outrageous "as a service" idea, please share.

Top 20 Most Commonly Used Open Source Licenses

My recent post "Tim Yeaton Snares Black Duck" gave me the encouragement to check out what Black Duck is up to these days.

While surfing the Black Duck Software website, I came across a very useful page worth bookmarking:
Top 20 Most Commonly Used Licenses in Open Source Projects

Black Duck's site says that they update the data in the table below on a daily basis, so please click over to their website for the latest data:
There is nothing unexpected or overly shocking in the data. For example, I have known that GPL 2.0 is the dominant open source license. I always thought the Apache 2.0 license was a little more prevalent, but the data is not far off from what I expected. GPL 3.0 appears to be doing really well since it is already above the Apache 2.0 and Mozilla Public License.

Anyhow, I figured I'd share the link. I'll certainly visit it periodically to stay abreast of the open source license landscape.

Virtualization Big Dog: VMware, Microsoft, Citrix, or Red Hat?

I was catching up on industry news today when I saw the following eWeek post: Red Hat Is Getting Ready to Take on VMware

It has been a while since I've written a "Big Dog" article, but this topic is worthy; so here goes.

Who is the virtualization big dog?

VMware is the incumbent big dog, of course. They have a compelling portfolio of offerings that are proven, feature-rich, and getting better all the time. Moreover, while I was at Princeton Softech, I was an avid and happy user of VMware's products.

Virtualization is big business these days and will only get bigger since it plays a fundamental and foundational role in cloud computing. VMware is faced with competitors interested in chipping away at their market dominance:
Just for fun, I've compared/contrasted the players in the Virtualization market with the players in the Enterprise Middleware market back in 2003/2004:
  • VMware and BEA: Early/dominant market leaders driving innovative technology
  • Microsoft and IBM: Huge players who think/execute over the long term
  • Citrix and Sun: Xen ignited these market dynamics; Java made the middleware market
  • Red Hat and JBoss/Tomcat: The power of bottom-up market groundswell
The middleware market leader was BEA Systems. IBM was the much bigger player applying top-down market pressure and working its usual long-term plan to gain market dominance. Sun was the vendor responsible for the technology that made the market but never became the market leader. And JBoss and Tomcat were generating significant and unyielding bottom-up market groundswell.

How did it play out? BEA became so focused on fighting IBM at the high end that they ignored/denied the bottom-up groundswell: BEA Chief Downplays Open-Source Alternatives. Alfred Chuang never gave credence to the JBoss or Tomcat threat and ultimately BEA got swept up by Oracle.

Bob Pasker (founder of Weblogic) had an interesting post after BEA got acquired by Oracle: JBoss (and possibly Tomcat) should never have happened. "JBoss launched an innovators dilemma attack against BEA, not with a revolutionary product, but with a revolutionary business model, one that BEA couldn’t hope to copy without cannibalizing its existing revenue stream. BEA fell right into the trap."

That Was Then But This Is Now
While there are some interesting similarities between the middleware and virtualization markets, the market dynamics today are clearly different. The open source model has clearly made its mark across many software markets. Neither Microsoft nor VMware are denying the power of open source or the threat that companies such as Red Hat pose to their business.

Add in the fact that VMware has Paul Maritz (ex-Microsoft executive) as their CEO and that changes things as well. While I don't like the article's title, I do agree with much of Chris Mellor's points in: VMware's one-trick pony: Destined to be a platform?. Chris highlights Maritz as an inspirational leader who has a great feel for where the market is heading.

So with all of that said, my answer to the question:

Who is the virtualization big dog?

VMware

Bottom-line: As long as VMware stays focused on creating great solutions to customer problems and honestly assesses the threats posed by the other market players, they should be able to retain their market leadership status for many years to come.

Programming Language Popularity

My 13 year old son has been programming in Lua, TI Basic and Assembler, ActionScript, JavaScript, and he's into C++/Dark GDK these days. While I've mostly focused on Java for the past few years, I've programmed in a wide range of statically typed and dynamically typed languages.

Since my son is just starting his programming journey, I naturally wondered:

What are the most popular programming languages these days?

I used tiobe.com and langpop.com to answer this question. Both sites provide programming language popularity statistics and rankings, and I was happy to see that Java, C, and C++ rank in the top three on both sites.

What I like about both of these sites is that they gather information across a wide range of search engines and websites in order to generate a popularity score. Neither site is focused on declaring the "best" programming language or the language in which the most lines of code have been written. They simply provide information that, as TIOBE states, "can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system."

TIOBE Programming Index for Feb 2009
TIOBE gathers information from Google, MSN, Yahoo!, and YouTube to calculate the ratings, and they have a great web page that defines how the TIOBE index is assembled. Below is a summary of the top 20 programming languages for February 2009. I especially like how they compare against last year's ranking so we can gauge how the language is doing year over year.

Below you will see that Java has been #1 the past two years. C++ and C# are on the rise. Visual Basic, PHP and Perl have declined however. I also find it interesting that while Ruby and Python generate a lot of buzz, neither has risen in rank over the past year.



LangPop Normalized Comparison on Feb 2, 2009
Below is LangPop's Normalized Comparison Chart that combines the data gathered across Yahoo, Craigslist, Amazon, Freshmeat, Google Code, and Delicious for 29 different programming languages. Click on the chart to see it more clearly.

Java is #2 behind C. Visual Basic is much lower in ranking than in TIOBE's ranking. Python, Perl, and Ruby are slightly higher than in TIOBE's results.


Conclusions?
Since I work at SpringSource and focus on enterprise Java (a la Spring) and dynamic languages that run on Java (a la Groovy/Grails), I'm pretty happy to see that Java not only maintains its relevance but continues to dominate as a top programming language.

With that said, the interest in dynamic languages such as PHP, Python, Ruby, and Groovy clearly tells me that developers crave more productivity and less complexity. Another reason I'm happy to be at SpringSource, since simplifying enterprise Java is our area of focus and passion.

Credits: I'd like to thank TIOBE and LangPop for maintaining and sharing the information on their website. They provide a valuable service and I will continue to visit their sites to stay abreast of how the programming language landscape evolves over the coming months and years.

Tim Yeaton Snares Black Duck

I agree with the sentiment behind Dana Blankenhorn's post asserting that it is "Happy days for Black Duck". As Dana states:
Having had the pleasure of working closely with Tim Yeaton before, during, and after Red Hat's acquisition of JBoss, I'm happy to see him join Black Duck as CEO. I'm quite familiar with some of Black Duck's offerings from prior due diligence efforts that used Black Duck to scan source code for the open source licenses contained within the code. Definitely useful for understanding any potential legal exposure you may have when acquiring medium to large code bases.

Anyhow, as Dana Blankenhorn points out, Tim Yeaton drove Red Hat's acquisition of JBoss in June 2006. Tim truly understood the value and strategic importance of expanding Red Hat's footprint to include middleware. And while the integration of the two companies was challenging (as are most integration efforts), Red Hat clearly benefited from the move.

Tim Yeaton did a great job of making all of the JBoss team feel comfortable and welcome at Red Hat. And when I left Red Hat in March 2008 for some "Purposeful Risk-Taking", I publicly thanked Tim and others at Red Hat / JBoss for making the experience a great one.

With Tim at the helm, I do indeed hope that there are "happy days" ahead for Black Duck.

Einstein on Relativity

I just ran across the following quote by Einstein:

"Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity."
Albert Einstein

I never thought of Einstein as a marketer (or a comedian for that matter), but he does a great job of communicating his theory in familiar yet memorable terms. And he made me laugh out loud while doing so.

Top 10 Application Development Products for 2008

I just viewed eWeek's new slideshow by Daryl Taft listing the Top 10 Application Development Products for 2008.

SpringSource dm Server is listed in the top 10 along with such products as Microsoft Windows Azure, Google App Engine, Amazon CloudFront, Adobe Flash Catalyst, Apple iPhone SDK, and others.

UPDATED Jan 4, 2009:
Daryl Taft also posted his Top 10 Application Development Stories of 2008; where SpringSource plays a nice role in the following stories:
  • OSGi (Open Services Gateway initiative) makes a big splash: Eclipse, NetBeans, the Spring Framework, Apache and others are looking to OSGi as the future of their Java deployment environments. Others see OSGi not only for deployment but for its programming model, which is starting to encroach on Java EE APIs.
  • The Spring Framework wins converts: Spring has become a leading player in enterprise Java because it helps to simplify development as opposed to Enterprise JavaBeans (EJBs) and J2EE (Java 2 Platform, Enterprise Edition) or Java EE (Java Enterprise Edition).

Now that's a great way to kickoff the New Year!
