  • Cloud architecture with state-saving middlebox scaling
    Patent number: 9705785
    Abstract: An enterprise computer system efficiently adjusts the number of middleboxes associated with the the enterprise, for example, with changes in demand, by transferring not only flows of instructions but also middlebox states associated with those flows. Loss-less transfer preventing the loss of packets and its state, and order-preserving transfer preserving packet ordering may be provided by a two-step transfer process in which packets are buffered during the transfer and are marked to be processed by a receiving middlebox before processing by that middlebox of ongoing packets for the given flow.

  • EFFECTIVELY OPERATING AND ADJUSTING AN INFRASTRUCTURE FOR SUPPORTING DISTRIBUTED APPLICATIONS
    Publication number: 20160344597
    Abstract: A facility for managing distributed system for delivering online services is described. For each of a plurality of distributed system components of the first type, the facility receives operating statistics for the infrastructure component of the first type. For each of a plurality of distributed system components of a second type, the facility receives operating statistics for the infrastructure component of the second type. The facility uses the received operating statistics for distributed system components of the first and second types to generate a model predicting operating statistics for the distributed system for a future period of time.
