Abstract
Virtual firewalls may be established that enforce sets of policies with respect to computing resources maintained by multi-tenant distributed services. Particular subsets of computing resources may be associated with particular tenants of a multi-tenant distributed service. A tenant may establish a firewalling policy set enforced by a virtual firewall for an associated subset of computing resources without affecting other tenants of the multi-tenant distributed service. Virtual firewalls enforcing multiple firewalling policy sets may be maintained by a common firewalling component of the multi-tenant distributed service. Firewalling policy sets may be distributed at multiple locations throughout the multi-tenant distributed service. For a request targeting a particular computing resource, the common firewalling component may identify the associated virtual firewall, and submit the request to the virtual firewall for evaluation in accordance with the corresponding firewalling policy set.
