vRealize Air Compliance - This is a new VMware SaaS offering which provides both compliance and remediation for your VM Configurations.There are many challenges here but the biggest one is efficiently capturing the changes and ensuring you do not impact the overall performance of your vCenter Server, especially with larger inventories. Custom Solution - A system that could periodically snapshot your VM configurations into some type of data warehouse or CMDB platform.Having said that, what options exists for customers today? Today, the process of identifying this information is actually quite difficult at least without resorting to a custom built solution which allows you to compare the configuration changes over time. This is definitely an area that VMware is investing heavily in and although I can not go into specific details, believe me when I say they are taking this very seriously both from a data completeness standpoint as well as simplifying the user experience. A question that I almost always see come up on a regular basis is around the topic of auditing or understanding what configuration changes were made to a given Virtual Machine.
