Measuring your entire server architecture involves many things from software versions provided by the package maintainer (Ubuntu/Debian, RHEL/CentOS, custom, etc), memory capacity of your machines, disk allocation, and so forth. Changes to this server architecture -- anything and everything -- should be managed in a controlled environment. AWS Config provides insight into this, notifying you of when any changes occur. They provide you with a constant stream of changes occurring, like getting Tweets whenever anything changes. Amazon already has AWS CloudWatch, this takes it a step further than monitoring performance, resource utilization, and operational health. It delves into what happens before performance thresholds are breached and operational health is diminished. It's an auditing tool, basically.
