Abstract:
1. A method for securing a customer domain in a virtualized multi-tenant environment, the method comprising: configuring, by a processor, a virtual machine (VM) for a customer in the customer domain; configuring, by the processor, a first virtual network interface (VNIC) in the VM, wherein the first VNIC enables a first application on the VM to access a second application in a second VM in the customer domain; assigning, by the processor, a first network address to the first VNIC, wherein the first network address is within a first network address range selected for the customer domain; configuring, by the processor, a second VNIC in the VM, wherein the second VNIC enables a third application outside the customer domain to access the VM in the customer domain, and wherein the second VNIC is configured to use an addressing specification used by a server of the third application; and configuring, by the processor, a third VNIC in the VM, wherein the third VNIC enables access from the first application to a fourth application executing outside the customer domain, and wherein the third VNIC is configured to use an addressing specification used by a server of the fourth application, thereby securing data communication relating to the customer domain from interference from data communication relating to a second customer domain.
