                          Service Oriented Architecture and Uncle Walter

                          This little slideshow from Michael Bell is an entertaining metaphor that introduces the concepts of service oriented architectures. The idea is that Uncle Walter has a business that is set up as silos the way most organizations set up their business processes (via their IT systems). He solves his problem by applying SOA principles. I think some people may object and say that Bell only mentions business processes--what does that have to do with architectures? Anymore, your business processes and your IT systems architecture are inseperable. You can't fix one without fixing the other.

                          Is SOA Dead?

                          Image by crazbabe21 via Flickr At the first of the year, Anne Thomas Manes wrote a provocative blog entry stating that SOA is dead. This week's Technometria podcast is a discussion with Anne about her thesis and what it means for practitioners and technologists. I think you'll enjoy it whether you're a fan of SOA or not. From the description at IT Conversations: Service-Oriented Architecture (SOA) provides ways to group functions around business processes, packaging them as services. This allows for better coordination between services. Anne Thomas Manes of the Burton Group joins Phil and Scott to discuss whether

                          Geopolitics and Cloud Computing

                          When I first read "Pentagon's New Map" and heard Tom Barnett talk about how he analyzed geopolitics, I realized that here was an theory a geek could love. Tom uses concepts like and system administration to talk about how the world does and ought to work. I got to interview Tom about his second book, Blueprint for Action and I'm anxious to get my hands on the new book, Great Powers. So, I wasn't surprised when a post from Tom called A nice primer on cloud computing and its relationship to SOA showed up in Snackr.

                          SOA Governance Podcast

                          As part of preparing for my upcoming tutorial in NYC on SOA Governance (Nov 8, 2007), I went back an listened to this interview I did with Todd Biske and Ed Vazquez for IT Conversations. Todd and Ed are so smart on this topic. I got a lot of good ideas from listening to this again. I changed some of the things I was going to talk about after reviewing this. If you don't care about enterprise IT, it will bore you to death, but if you do, there's some great ideas here.

                          SOA Governance Tutorial

                          I'm going to be doing a day-long tutorial on SOA governance at the InfoWorld SOA Executive Forum in New York on November 8th. If you register before October 7th, it's $695. After that it's $795 until November 5th. Then the price goes up to $895. Here's the details: Counterintuitive as it may seem, SOA requires more organizational discipline than previous development models. Your intuition might tell you that flexibility results from less rules, not more, but that's not the case. Standardization provides the underpinnings for SOA across an organization. To prevent IT from being overwhelmed by this new complexity,

                          Syndication Oriented Architectures

                          Two of the people I respect the most, Jon Udell and Rohit Khare are together in one podcast: Jon's latest from his weekly Interviews With Innovators podcast on IT Conversations. Jon has a short write-up on his blog about the podcast and it's topic: syndication oriented architectures. SynOA was born on the open web and is now creeping into the enterprise. To understand why, just consider Facebook. It is a deeply syndication-oriented application. Although Facebook users never have to think about it in these terms, they are constantly publishing events onto a syndication bus while at the same time

                          Making SOA Governance Collaborative

                          The irony of loosely coupled SOA systems is that they require more, not less rules. Governance manages the rule making process. My InfoWorld feature on SOA governance Teaming up for SOA came out this week. I was writing this article at about the same time we did this Technometria podcast with Todd Biske and Ed Vasquez.

                          Using Amazon Web Services

                          I just posted a piece at Between the Lines about our latest Technometria podcast with Jeff Barr and Doug Kaye. We discussed using Amazon Web Services to build sophisticated Web applications. Lots of good things in the podcast about business models, asynchronous programming, and so on. This was a fun podcast to do. Not only was the content exciting, but it was also a bit of a challenge from the recording angle as well. Jeff was in my office with me and Doug, Scott, and Matt were on the phone. I recorded the whole conversation using AudioDesk and a

                          Governance As Collaboration: Managing Layers 8 and 9

                          I'm doing a feature for InfoWorld on SOA governance and collaboration. The genesis was a short piece I did for InfoWorld on emerging collaboration options. Somehow Eric Knorr and I got talking about how SOA was a formalization of how collaboration can happen in building distributed applications and that governance was a key part of all that. Governance is a term that has been much hyped in the last year, but that's because it's so important. Like most things, the technology of SOA isn't the hard part--its what Rohit Khare calls level 8 and 9 in the OSI seven-layer

                          Testing as an SOA Management Strategy

                          "Testing isn't an event" says John Michelsen, the Chief Architect and a co-founder of iTKO, Inc. I was the moderator on an InfoWorld Webcast this afternoon where John presented. SOA brings new challenges to testing. Testing individual services is similar to code-level testing in any other development effort, but testing integration points, especially when there are dozens of hundreds of them is more difficult. One issue is that business analysts and QA folks need to be involved in the testing process. To make that more difficult, SOA testing is something that needs to happen continuously. If the business side,

                          SOA Testing Webcast

                          I'm moderating a webcast for InfoWorld on Wed. The topic is testing in an SOA environment. iTKO is the sponsor and, hence, the presenter. I'm looking forward to it--SOA testing isn't a topic that get's much play, but's its important. The Webcast is free, so if you've got time in Wed (Jun 14) at 11AMPST, tune in. An interesting sidenote: while we were doing the dress rehersal, I dsicovered that the ON24 control console doesn't support anything but IE. Argh! (This isn't true, of the audience app--it works fine cross platform.) But I just updated to my new MacBook

                          SOA Forum Wrap-up

                          Halley Suitt(click to enlarge) My laptop was giving me grief yesterday (I think it's a memory problem) so I didn't get to everything I was planning on writing up. For example, I went to Halley Suitt's talk at Syndicate in the afternoon. Halley is one of the early bloggers and a great writer. She writes Halley's Comment and is the CEO of Top Ten Sources. She's also a sometime contributor at IT Conversations, doing a show called Memory Lane (I'd like her to do more shows--hint, hint). The panel on SOA Governance went very well and we had some great

                          SOA Name Change?

                          I got an email from Pheloxi in the Netherlands who informed me that SOA is the Dutch acronym for sexually transmitted disease. I guess if InfoWorld does a European version of the SOA forum, they may want to change the name. :-)

                          Getting Started with SOA

                          I'm at the InfoWorld SOA Executive Forum today. I'm moderating a panel on SOA governance and speaking on digital identity. The conference is completely sold out. I was part of a team that wrote a feature for InfoWorld last week on the SOA lifecycle. I've watched (and helped) InfoWorld move into this space over the last few years and I think they've done more than just report on what's happening: they're part of the conversation and clarifying concepts in helpful ways.

Ed's the Group Manager of the Web Service Integrations & SOA. Jeff Schneider of MomentumSI Johannes Viegener of Software AG. Johannes is Vice President of the R&D Crossvision Suite Michael Hill of HP. Mike is the Global Director for Enterprise Architecture & Governance This should be a great panel.

                          Bret Dixon on SOA

                          in his keynote presentaiton, Bret Dixon of BEA made an interesting comparison. One viewpoint is that of the single technology stack that has these characteristics: invest to reach homogeneity get everything you need from one vendor replace what you have periodic releases will give you enhancements The other view point is a single service nertwork that has these characteristics: heterogenous products make up a network commitment to open standards uses different products to get needed functionality incremental increase in capacity and functionality SOA means that the software the links applications become more important and are among the most improtant

                          Jeff Gleason on Achieving Reusability with SOA

                          I'm at InfoWorld's SOA Executive Forum this morning in San Francisco. I'll be conducting a panel on SOA governance later this afternoon. There's a sellout crowd. InfoWorld really knows how to put these things together. I also know from working with Eric Knorr, Steve Fox, and other editors at InfoWorld that they try really hard to make sense of this, create good ways to explain it, and develop sound advice. The opening keynote is by Jeff Gleason, Director IT Strategies, Transamerica Life Insurance Company. He's speaking, from experience, on achieving reusability using SOA. Transamerica provides life insurance, pensions, and

                          SOA Governance Panel

                          I'll be moderating a panel on SOA governance at InfoWorld's SOA Executive Forum March 16 in San Francisco. This will be a follow-on to the feature I did on SOA governance that ran in January. The panelists will be: Todd Biske of AG Edwards. Todd blogs actively about SOA. He had a recent piece about governance with an analogy to voting that I enjoyed. Ed Vazquez of Sprint-Nextel. Ed's the Group Manager of the Web Service Integrations & SOA.

                          SOA in the Public Sector

                          I'm quoted in an article in Public CIO magazine. I was interviewed for this story on the use of SOA and Web services in the government so long ago, I can hardly remember it. The article, especially the last line, makes me look less enthusiastic about SOA in the public sector than I am. I think public sector CIOs have a great opportunity to use the governance powers that they already have, in connection with relatively modest expenditures on infrastructure to build real connectivity between departmental silos.

                          SOA Governance Feature

                          The SOA Governance feature I did for InfoWorld is up today. There are four parts: Governing SOA - Rules, standards, and policies are the difference between playing with SOAP and real SOA. A degree of tolerance for SOA -- There's a danger in going too far. Exclusive: Infravio brings structure to unwieldy SOA -- A review of X-Registry 5, one of a handful of tools that form and infrastructure for governance. Understanding UDDI -- A quick reference to UDDI-compatible registries. This was a fun series to do and I learned a lot writing it. Steve Fox wrote an intro

                          Stable Architectures

                          There's a very informative article in InfoWorld about how Con-Way, the trucking company used SOA to migrate away from their legacy applications piecemeal. The effort required making the architecture explicit first, with the right level of granularity, and then building interfaces. Then various parts can be changed as needed and reintegrated to create new apps. The article says: Although the Con-Way effort began eight years ago, the basic architecture has remained stable and has allowed the company to change its technologies while maintaining the underlying business logic and adding new business logic as the market demands.

My first draft of a graphic is shown on the right. Here's text I'm thinking of including with it. Naturally, it has been simplified to meet space requirements. The question is "does this capture the spirit of UDDI and communicate useful information or does it confuse because of details left out?" Help

                          SOA Governance Links the Producer and Consumer Lifecycles (click to enlarge) I'm trying to put together some graphics for the SOA Governance article I'm working on. Once concept I like is the idea that governance links the producer and consumer lifecycles. I've tried to capture that idea (roughly) in the graphic at the right. I'd sorely appreciate comments on what's wrong with it and what I'm missing or might communicate more clearly another way. One thing that confused me for a second was that I wanted to put "discover" as a "design time" activity, but that's really only "design time"

                          The Tolerance Continuum

                          Dion Hitchcliffe has a nice graphic on his blog showing a tolerance continuum. Notice at the top are things like HTML, RSS and folkonomies. At the bottom are ontologies, RDF, and enterprise applications like CRM and ERP. I spoke with Dion yesterday and he talked to me about governance mistakes he sees clients making. The number one problem is something he called the "tyranny of the ?MUST understand' flag." You get a SOAP-based Web service loaded up with WS-* header elements all tagged 'MUST understand' and you end up with something every-bit as much a central command and control

                          Toward More Tolerant SOA

                          In writing the SOA governance piece for InfoWorld, I've been thinking a lot about how organizations can misuse governance. I've been spending some time reading what Jeff Schneider and Dion Hitchcliffe have to say on the subject of tolerance. One thing that springs to mind is to get overly restrictive in ways that cover up poor design and reduce loose coupling. Here are a few examples I was turning over in my mind. Suppose that my organization is making a commitment to SOA. One of the issues that will come up that requires governance is choosing a standard for

                          SOA Governance Questions

                          As I work on my SOA governance story, I came up with a list of questions for companies about SOA governance. Feel free to leave comments or to contact my directly with answers and ideas. As I dig into this, it's clear there's a book waiting to be written around this topic. How would you characterize the stage your company is at in deploying SOA-based systems? (some examples; pilot, beginning, advanced) Do you have a strong Enterprise IT Governance process now? If so, how is you SOA governance related to IT governance? Is it just a piece of it

                          SOA Governance Article

                          I'm working on an article on SOA governance for InfoWorld. If you have ideas, I'd love to hear them. What I'm not looking for is emails that say things like the one I got yesterday. The PR person claimed her client has been "delivering SOA governance" to customers, like you can buy governance by the gross. I've been collecting some articles I run across at this del.icio.us tag. I'm particularly interested in hearing about what people doing large SOA deployments are doing about governance.
