Abstract: Providing high availability in a distributed networking platform includes detecting that an original primary service engine is unavailable, wherein: the original primary service engine and a plurality of secondary service engines are configured to provide one or more network applications associated with a virtual Internet Protocol (VIP) address; the original primary service engine and the plurality of secondary service engines are in active-active configuration mode; and the original primary service engine is configured to respond to Address Resolution Protocol (ARP) requests designating the VIP address. Additionally, providing high availability in a distributed networking platform further includes determining that a controller is unavailable; and configuring a selected secondary service engine as the next primary service engine.

Abstract: In an embodiment, a method for propagating ordered object changes includes synchronizing a client's version of configured objects with a configuration server's version of configured objects, including obtaining a list of object identifiers and a first version identifier of an object from the server. The method includes recursively getting objects at a version identified by the first version identifier from the server to construct an object graph on the client. The method includes subscribing to a configuration stream associated with the server (including sending the first version identifier) and obtaining responses from the configuration server where a response includes a second version identifier and a corresponding object identifier for an object that has been reconfigured between the first version and the second version. The method includes getting an updated version of the objects identified in the stream by the second version identifier to update the object graph.
