Finding the need to investigate extending the built in Service Manager CMDB and being relatively new to Service Manager I found this blog post by MVP Marcel Zehner an invaluable starting point.
One thing you have to keep in mind with Private Cloud Computing is the fact that requirements for CMDB change dramatically. Not only that your CMDB needs to manage new classes (e.g. Virtualization Hosts, Hypervisors, Guests, Clouds etc.) and Relationships (e.g. VM belongs to Cloud, Cloud uses Virtualization Hosts, Virtualization Hosts run Hypervisor etc.,), but it must also be able to be enough dynamic to support Cloud scenarios. Cloud configurations are dynamic (e.g. VM Live Migration, VM Storage Migration), configuration changes can happen any time and can be triggered in many different situations (e.g. System Maintenance, End user Self Service). I had a speech about this topic some days ago at a Microsoft TechNet Event in Switzerland and I’d like to share that information with my blog readers.
