EASOT?

We just published a white paper about the Enterprise Architectural Space Organizing Table. Basically, this is a table for categorizing architectural artifacts such as patterns. It owes a great deal to Zachman, but really builds out the concepts of roles and viewpoints. In addition to the white paper, you can get a PDF of the table itself.

What’s ultra-cool about this table is that it’s what the p&p group uses internally. The white paper maps every pattern MSFT has published into the table. You can also see the EASOT viewpoints in action in the Project Notebook section of Integration Patterns. When I saw a print of the table hanging on the wall in p&p’s building, I knew I wanted to see it published online. Love it or hate it, it’s real.

What do you think? Obviously, we’re planning on building on EASOT going forward. Is this useful? Valuable?

Pat Sings To Mr. CIO Guy

In addition to being a history buff and architecture expert, Pat likes to sing – typically parody songs of his own creation. He’s written many, but we actually broke down and got a license for Don McLean’s classic “American Pie“. Pat performed his version – a speculative retrospective titled “Mr. CIO Guy” – at the end of his TechEd Europe architecture track general session. You can watch a streaming version on Channel 9. Lyrics are posted on my MSDN Blog. Major thanks to Breakfast of Champions for getting it encoded so fast and to Jeff for getting it posted so fast.

On a more serious note, we are recording all of Pat’s TechEd sessions for the Architecture Strategy Series. Watch this space for details.

TechEd Sessions Online

Streaming producer presenations from TechEd US have been posted. However, the streaming presenation site has the same lack-of-url-addressability issue that TechEd Breakout session list had. Is it so hard to just post a simple HTML file with a list of all the sessions in a track? <sigh>

Anyway, here are links to the top 5 sessions from this year’s architecture track. For those who could not make it to TechEd (or were there, but missed these sessions) enjoy!

  1. Realizing SOA by John deVadoss & Ron Jacobs
  2. Data in SOA by Harry Pierson (i.e. yours truly)
  3. Patterns in the Enterprise by Gregor Hohpe
  4. Improving Application Perf & Scale by Chris Kinsman
  5. Building Apps with P&P App Blocks by Wojtek Kozaczynski

Update: The streaming site has been taken down, so none of the links work anymore. Sorry about that. We will be updating the Architecture Strategy Series at some point in the future with at least the Realizing SOA and Data in SOA talks.

Pat and John Are Blogging Again

I keep bugging Greg about better folder hierarchy support in NewsGator. While I have some news feeds directly under my news folder (Don Box, Dilbert, my dad) I categorize most of my feeds into subfolders. One subfolder is for MSFT architects – my teammates, Michael, Keith & Kevin among others. That folder is where I typically start reading, esp. when I’m a week behind.

After a long absence, both Pat and John are blogging again. Pat’s been busy working on his new talks that he will be presenting at TechEd Amsterdam. We will be taping them for inclusion in the Architecture Strategy Series. He’s got a surprise planned for the end of his Metropolis overview talk (GNLARC) that I’m in charge of getting up on the web as soon as possible after it happens…watch this space…

John has written two pieces – on SOA and smart clients. John’s amped about the SCAG and he blogs about his smart client thoughts. I liked his observation that building browser-based apps “is all about service provider ease of delivery” while smart clients are “all about service consumer ease of use”. Today, ease of delivery wins out over ease of use, but I wonder how long that will last.

However interesting John’s views on smart clients are, I typically have long conversations with him about the finer points of SOA. A conversation that starts with “Got a sec?” typically turns into an extended discussion with crowded whiteboards. What I’ve realized recently is that John and I tend to approach a topic very differently. John is very pragmatic, so he tends to disagree with my more radical opinions (such as the endangered middle tier) which aren’t really feasible in the short term. I, on the other hand, start from a desired state and work backwards, trying to figure out what short term investments will lead to the long-term ideas. I used to think John and I disagreed about the desirable granularity of services. What it turns out is that we agree about what we want, but he focused on the fact we can’t feasibly build fine-grained services in the short term while I glossed over that fact and thought about what we needed to make fine-grained services feasible in the long term. Neither viewpoint is right or wrong, in fact they are very complementary. John keeps me grounded in reality while I push the limits of his event horizon. Among the recent topics of debate:

  • How fine grained should services be?
  • Should customers be thinking about building domain specific languages?
  • How will the role of the ISV’s and SI’s evolve?
  • How much of a typical enterprise should be outsourced?
  • Is a service-oriented architecture more data-centric or process-centric?
  • What would a requirements modeling language look like?
  • What is the most important criteria for evaluating software systems for the enterprise?

Keep it up, John.

DevHawk on TheServerSide.net

TSS.net just published a new Tech Talk, this time with yours truly. Tech Talks are interviews with “.NET luminaries” (their name). Previous talks on TSS.net include Pat and Simon from my team as well as others such as Don Box and Scott Guthrie. Nice company to be in!

The interview is pretty broad reaching – we spend thirty minutes about architecture (with a lower case a), community, patterns, aspects, messaging, service oriented way plus job advice for Ted’s 10 year old son.
