This is an interesting topic. I would add Storage as a distinct Infrastructure at this point. Storage, especially Virtual Storage, will become part of the fabric of IT. All Services and applications will rely on the storage devices.

Another interesting component is Virtualization as a technology stack at all layers: Storage, Network, OS, and Application. As the the datacenter becomes more dynamic, there will be increasing complexites introduced by these abstractions. Where does that fit in the model?

Also, did you intend to convey a hierarchic relationship between configuration - security - performance - availability? Do you believe it moves in that direction? My thought is configurations provide services. The different configurations result in different resultant characteristics and behaviors with metrics such as how secure, how compliant, how available, etc.

Where do you put an ITIL type function? Where’s the Service Desk? The CMDB? This is where the Processes shoudl start and end with interaction with the other tools/functions.

Also, true Analytics would be looking down at or across all of this to help steer IT in a process of continual improvement across people, process and technology.

This is good stuff. Keep it going!

That’s quite the ambitious entry. I’m interested to see how your reference model develops. Let me know if there’s anything I can do to help.
