Enterprise application integration patterns for IT management: a blast from the past or from the future?

In a recent blog post, Don Ferguson (CTO at CA) describes CA Catalyst, a major architectural overhaul which “applies enterprise application integration patterns to the problem of integrating IT management systems”. Reading this was fascinating to me. Not because the content was some kind of revelation, but exactly for the opposite reason. Because it is so familiar.

For the better part of the last decade, I tried to build just this at HP. In the process, I worked with (and sometimes against) Don’s colleague at IBM, who were on the same mission. Both companies wanted a flexible and reliable integration platform for all aspects of IT management. We had decided to use Web services and SOA to achieve it. The Web services management protocols that I worked on (WSMF, WSDM, WS-Management and the “reconciliation stack”) were meant for this. We were after management integration more than manageability. Then came CMDBf, another piece of the puzzle. From what I could tell, the focus on SOA and Web services had made Don (who was then Mr. WebSphere) the spiritual father of this effort at IBM, even though he wasn’t at the time focused on IT management.

As far as I know, neither IBM nor HP got there. I covered some of the reasons in this post-mortem. The standards bickering. The focus on protocols rather than models. The confusion between the CMDB as a tool for process/service management versus a tool for software integration. Within HP, the turmoil from the many software acquisitions didn’t help, and there were other reasons. I am not sure at this point whether either company is still aiming for this vision or if they are taking a different approach.

But apparently CA is still on this path, and got somewhere. At least according to Don’s post. I have no insight into what was built beyond what’s in the post. I am not endorsing CA Catalyst, just agreeing with the design goals listed by Don. If indeed they have built it, and the integration framework resists the test of time, that’s impressive. And exciting. It apparently even uses some the same pieces we were planning to use, namely WS-Management and CMDBf (I am reluctantly associated with the first and proudly with the second).

While most readers might not share my historical connection with this work, this is still relevant and important to anyone who cares about IT management in the enterprise. If you’re planning to be at CA World, go listen to Don. Web services may have a bad name, but the technical problems of IT management integration remain. There are only a few routes to IT management automation (I count seven, the one taken by CA is #2). You can throw away SOAP if you want, you still need to deal with protocol compatibility, model alignment and instance reconciliation. You need to centralize or orchestrate the management operations performed. You need to be able to integrate with complementary products or at the very least to effectively incorporate your acquisitions. It’s hard stuff.

Bonus point to Don for not forcing a “Cloud” angle for extra sparkle. This is core IT management.
