Techniques are described for identifying “out-of-band” modifications to an interrelated set of computing resources, also referred to herein as a computing resource stack, that was provisioned at a service provider network using an infrastructure modeling service. An infrastructure modeling service generally allows users to describe a computing resource stack in a text file or other type of descriptive representation, referred to herein as an infrastructure template, and to automatically provision computing resource stacks defined in templates at a service provider network. Users may at times make so-called out-of-band modifications to one or more computing resources of a provisioned computing resource stack, either inadvertently or in response to time-sensitive demands, where an out-of-band modification is made outside of the infrastructure modeling service.
