The future (2006 version), has arrived

Remember 2006? Things were starting to fall into place for IT management integration and automation:

• SDD was already on its way to cleanly describe/package/manage the lifecycle of simple and composite applications alike,
• the first version of SML came out to capture all the relevant constraints of complex and composite systems and open the door to “desired-state management”,
• the CMDBf effort was started to seamlessly integrate all sources of configuration and provide a bird-eye view of your entire IT infrastructure, and
• the WSDM/WS-Management convergence/reconciliation was announced and promised to free management consoles from supporting many resource discovery, collection and control mechanisms and from having platform/library dependencies between the manager and its targets.

It looked like we were a year or two from standardization on all these and another year or two from shipping implementations. Things were looking good.

Good news: the schedule was respected. SDD, SML and CMDBf are now all standards (at OASIS, W3C and DMTF respectively). And today the Eclipse COSMOS project announced the release of COSMOS 1.1 which implements them all. The WSDM/WS-Management convergence is the only one that didn’t quite go according to the plan but it is about to come out as a standard too (in a pared-down form).

Bad news: nobody cares. We’ve moved on to “private clouds”.

Having been involved with these specifications in various degrees (a little bit on SDD, a fair amount on SML and a lot on CMDBf and WSDM/WS-Management) I am not as detached as my sarcastic tone may suggest. But as they say in action movies, “don’t let sentiments get in the way of the mission”.

There is still a chance to reuse parts of this stack (e.g. the CMDBf query language) and there are lessons to learn from our errors. The over-promising, the technical misjudgments, the political bickering, the lack of concrete customer validation, etc. To some extent this work was also victim of collateral damages from the excesses of WS-* (I am looking at you WS-Addressing). We also failed to notice the rise of the hypervisor in our peripheral vision.

I tried to capture some important lessons in this post-mortem. For the edification of the cloud generation. I also see a pendulum in action. Where we over-engineered I now see some under-engineering (overly granular interaction models, overemphasis on the virtual machine as the unit of everything, simplistic constraint models, underestimation of config/patching issues…). Things will come around and may eventually look familiar (suggested exercise: compare PubSubHubBub with WS-Notification).

As long as each iteration gets us closer to the goal things are good.

See you in 2012. Same place, same day, same time.
