Abstract
An efficient elastic enforcement layer (EEL) for realizing security policies is deployed in a cloud computing environment based on a split architecture framework. The split architecture network includes a controller coupled to switches. When the controller receives a packet originating from a source VM, it extracts an application identifier from the received packet that identifies an application running on the source VM. Based on the application identifier, the controller determines a chain of middlebox types. The controller further determines middlebox instances based on current availability of resources. The controller then adds a set of rules to the switches to cause the switches to forward the packet toward the destination VM via the middlebox instances.
