1. A system, comprising:
first computing resources at a first site;
second computing resources at a second site, wherein the first site is at a different geographic location than the second site, wherein the first computing resources and the second computing resources are communicatively coupled via a public network; and
wherein the first computing resources are configured to:
receive a packet from a first host at the first site, the packet comprising (i) a destination of a second host at the second site and (ii) a first source identifier value for a first computing resource group as defined by a namespace of the first site, wherein the first host is assigned to the first computing resource group;
wherein the second computing resources are configured to:
receive the packet via the public network from the first site; and
forward the packet to the second host after the first source identifier value in the packet is translated to a second source identifier value for a second computing resource group as defined by a namespace of the second site.
