Techniques are provided herein for detecting that virtual data center services provided to one of at least two customers are being subjected to an attack, wherein the virtual data center services are provided to the least two customers using a same first set of physical servers via a first network element such as a physical access switch, and responsive to detecting that virtual data center services provided to the one of the at least two customers are being subjected to an attack (e.g., a virus or denial of service attack), the technique causes the virtual data center services provided to the one of the at least two customers to be migrated to, e.g., instantiated on, a second set of physical servers that is not accessible via the first network element.
