A large enterprise has virtualized heavily in their data center. All virtual machines in the enterprise are built from standardized baseline templates. Based on these image templates, they have set configuration best practices and implementation workflows.
Recently, the company has started to see performance issues on several production-critical virtual guests. In responding to the performance issues, the cause was found to be incorrectly configured vNIC parameters in the virtual guests.
Which service should be implemented to identify deviations in the deployed servers from the baseline templates, and to remediate any such deviations?

B.
CMDB automation
– This is an approach of self-Healing systems:
One approach is to integrate a CMDB with an automation and orchestration tool. Using API calls, SNMP, or other configuration gathering method, the status of a subsystem can be compared to what is considered normal as defined by the SLA for that subsystem. If it is not in compliance, the automation and orchestration components can be invoked to put things back they way they should be.
