Abstract: A determination is made at a network connected device that a network policy is to be verified. The network policy is applied to network packets sent to an endpoint within a network, and the application of the policy to network traffic can result in at least two outcomes. Another determination is made at the network connected device that a switch is provisionable to host the endpoint. The network connected device provisions a simulated endpoint version of the endpoint at the switch to host the policy. At least one packet is sent to the simulated endpoint via the network connected device for each of the at least two outcomes of the policy. At least one response is received by the network connected device from the simulated endpoint indicating how the policy was applied to each of the packets.

Abstract: Disclosed herein are systems, methods, and software for enhancing application update processes. In an implementation, a delta file is received in a data center that hosts various instances of a service application. The delta file represents a difference between a new version of the service application and a previous version of the service application. An instance of the service application installed in the data center is removed from service temporarily in order to update it from the previous version of the service application to the new version of the service application. Upon initiating and completing an update of the instance of the service application to the new version of the service application using at least the delta file, the instance is returned to service.
