In this video, we continue our discussion of configuration management systems. We talk about state assertion, what states of a host we might care about, the CAP theorem and other fallacies of distributed systems, idempotence, eventual consistency and convergence, and the overlap of CM systems with other infrastructure components, yielding, eventually, infrastructure as a service.
