Abstract: A centralized namespace controller allocates addresses in a distributed cloud infrastructure on-demand. Upon receiving a request to allocate addresses for a network to be provisioned by a cloud computing system included in the distributed cloud infrastructure, the centralized namespace controller allocates a network address that is unique within the distributed cloud infrastructure. Further, the centralized namespace controller allocates a range of virtual network interface cards (NIC) addresses that are unique within the network. The centralized namespace controller then allocates addresses from the range of virtual NIC addresses on an as-requested basis—when a virtual NIC is being created by the first cloud computing system on the network. Advantageously, by centralizing the allocation of addresses and dedicating independent NIC address ranges to different cloud computing systems, the centralized namespace controller enables stretched L2 networks between cloud computing systems while preventing duplicated addresses on the stretched networks.

Abstract: An example method of optimizing connectivity between data centers in a hybrid cloud system having a first data center managed by a first organization and a second data center managed by a second organization, the first organization being a tenant in the second data center. The method includes probing a wide area network (WAN) with test packets by varying an internet protocol (IP) flow tuple of the test packets across a set of IP flows. The method includes identifying a plurality of paths between a gateway of the first data center and another gateway of the second data center associated with the set of IP flows. The method further includes selecting an IP flow from the set of IP flows for an application executing in the first data center. The method further includes establishing a path-optimized connection between the gateway and the other gateway through the WAN having the selected IP flow for use by the application.

Abstract: One or more embodiments provide techniques for migrating virtual machines (VMs) from a private data center to a cloud data center. A hybrid cloud manager determines a scope of migration from the private data center to the cloud data center. The hybrid cloud manager groups each VM included in the scope of migration into one or more clusters. The hybrid cloud manager defines one or more migration phases. Each migration phase comprises a subset of the one or more clusters. The hybrid cloud manager generates a migration schedule based on at least the one or more migration phases. The hybrid cloud manager migrates the VMs from the private data center to the cloud data center in accordance with the migration schedule.

Abstract: Techniques leveraging CPU flow affinity to increase throughput of a layer 2 (L2) extension network are disclosed. In one embodiment, an L2 concentrator appliance, which bridges a local area network (LAN) and a wide area network (WAN) in a stretched network, is configured such that multiple Internet Protocol Security (IPsec) tunnels are pinned to respective CPUs or cores, which each process traffic flows for one of the IPsec tunnels. Such parallelism can increase the throughput of the stretched network. Further, an L2 concentrator appliance that receives FOU packets is configured to distribute the received FOU packets across receive queues based a deeper inspection of inner headers of such packets.

Abstract: Techniques for stateful connection optimization over stretched networks are disclosed. In one embodiment, traffic of virtual machines (VMs) that are live-migrated from a data center to a cloud is temporarily tromboned back to the data center to preserve active sessions. In such a case, a stretched network is created that includes a network in the data center and two stub networks in the cloud, one of which is route optimized such that traffic does not trombone back to the data center and the other which is not so optimized. A VM that is live migrated to the cloud is first attached to the unoptimized network so that traffic tromboning occurs. Thereafter, when the VM is powered off (e.g., during a reboot), in a maintenance mode, or in a quiet period, the VM is switched to the route optimized network.

Abstract: A hybrid cloud computing system is managed by determining communication affinity between a cluster of virtual machines, where one virtual machine in the cluster executes in a virtualized computing system, and another virtual machine in the cluster executes in a cloud computing environment, and where the virtualized computing system is managed by a tenant that accesses the cloud computing environment. After determining a target location in the hybrid cloud computing system to host the cluster of virtual machines based on the determined communication affinity, at least one of the cluster of virtual machines is migrated to the target location.

Abstract: A virtualized computing environment includes a plurality of host computers, each host being connected to a physical network and having a hypervisor executing therein. To provision a virtual machine requiring a connection to a virtual network in one of the hosts, a candidate host for hosting the virtual machine, the candidate host having the virtual network configured therein, is selected. A request is then made for a status of the virtual network to the candidate host. The status of the virtual network is then received from the candidate host. If the virtual network is available, then the virtual machine is deployed to the candidate host. If the virtual network is not available, then a second candidate host is selected for hosting the virtual machine.
