Business. Via:hortovanyi. For:fredwilson. Rlmrdl. » Meet AOS, the polar opposite of SOA. Many organizations -- often prodded by vendors -- are setting out with the intentions of building out service oriented architectures, in hopes of cutting their development times and increasing business agility.
But SOA doesn't come in a neat package. As a result, the stage where many organizations are at these days is not SOA, but rather, its mirror image, AOS -- an Agglomeration Of Services. Let's consider the differences: Governance: In SOA, there is are well-established, and increasingly automated, governance mechanisms, backed up by federated registries, that enforce standards and enable review and vetting of new services.In AOS, services are created by various groups, are thrown over the wall, and who knows or cares who or how many applications are using the services?
Organization: In SOA, corporate management is aware of the potential benefits of shared services to the business, and one or more line-of-business executives are involved in planning and governance.

Back when my job as Salon managing editor involved overseeing our daily production, I noticed that, every spring and fall, almost without fail, our publishing system would experience a glitch of some kind on the weekend that the clocks got moved forward or back — nothing serious, mind you, but enough to throw a wrench in the works of our site updates.
It wasn’t a single bug, but some sequence of related bugs, so we’d fix one and then six months later something else would happen. Eventually we got in the habit of just making sure that one of the developers kept a close eye on things when that weekend rolled around. It was prudent. I thought of that as I read these accounts that are filtering out about the F-22 Raptors that, the speculation is, lost their bearings when they crossed the International Date Line.
The F-22 costs $125 million or so and its operating system is written in 1.5 million lines of Ada code.

There was an interesting and passionate thread of follow-up commentary to my post from earlier this month, "Service Component Architecture gets slapped around a bit.
" Consultant David Chappell initially raised questions about the positioning of SCA as supporting SOA, but Oracle's Dave Chappell responded that SCA has plenty to do with SOA: "The primary value proposition of SCA is about providing a common model for component assembly for building services. What's so 'unSOA' about that? " Consultant David Chappell provided some additional clarification to his remarks, noting that he is a fan of SCA, and agrees with his Oracle namesake that SCA does provide a common model for component assembly. However, that doesn't take away from the fact that SCA does have some unSOAish characteristics, he adds.
Namely, that "all of the components in this assembly must be running in the same vendor's SCA container. Looking back on 2007. About this time last year I did a little retrospective ... given that it's that time of year again, I thought I'd have a bit of a recap of what I highlighted last year, and some new stuff since.
Last year's model: eMusicStill subscribed and still happy - not a lot of mainstream stuff, just the way I like it. last.fmA few more people have taken it up. A little flicker of apprehension when CBS bought it, but so far no obvious ill effects. My conclusion: I don't listen to enough music ... VRMThe customer-centric and controlled idea has gained quite a lot of traction - not as much concrete 'product' from it as I hoped, but a lot of smart people are involved. LinkedinWas pretty freaked this year by the number of work colleagues who got into Linkedin this year - it got a bit strange when I invited our CEO to connect whie he was using his laptop for a presentation ... damned Outlook notification all over the projection screen! CoCommentGave itself a facelift through the year, and nearly lost me.
