1. A method for emulating physical layer impairments in a cloud computing environment, the method comprising:
at a test controller for configuring a plurality of entities in a cloud computing environment using a dynamic impairment container network interface (DI-CNI) capable of instructing one or more of the plurality of entities to implement or emulate one or more physical layer related impairments:
configuring, using a first DI-CNI message comprising first configuration information, a first container hosting a first application, wherein the first configuration information includes information for implementing or emulating a first physical layer related impairment for impairing traffic to or from the first container;
configuring, using the first DI-CNI message or a second DI-CNI message comprising second configuration information, a second container hosting a second application, wherein the second configuration information includes information for implementing or emulating a second physical layer related impairment for impairing traffic to or from the second container;
initiating a test session causing test packets to interact with the first container and/or the second container, wherein the test packets are impaired by the first physical layer related impairment and/or the second physical layer related impairment; and
during the test session, sending a third DI-CNI message comprising third configuration information for modifying the first physical layer related impairment and/or the second physical layer related impairment.
