Abstract
Systems and methods are described for facilitating custom DNS configurations relating to one or more serverless functions executing in one or more function execution environments. A DNS system may be implemented in a serverless execution environment with at least one host system hosting the one or more one or more function execution environments. The DNS system may facilitate implementation of custom DNS configurations received from an end user with respect to the one or more serverless functions. The DNS system may store DNS records in a DNS cache in compliance with DNS configurations. The DNS system also be isolated from the function execution environments in a separate execution environment such that the DNS cache of the DNS system may serve as a source of truth from which to assess that a serverless function of a virtual machine instance has been compromised by a malicious actor, such as through malware.
