Abstract: Techniques for safe oversubscription of connection tracking entries are described. A method for safe oversubscription of connection tracking entries may include receiving a request for an allocation of a resource on a physical host in a provider network, the request received by a resource allocation monitor from an instance hosted by the physical host, determining a resource availability on the physical host, the resource availability based on a total amount of the resource on the physical host, a reserved amount of the resource to a plurality of instances hosted by the physical host, and a shared amount of the resource, and granting or denying the resource allocation based at least on the determined resource availability.
