    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: 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: Exemplary methods, apparatuses, and systems include a first host device determining that a first packet from a first virtual machine (VM) within the first host device is to be transmitted to a second VM on a second host device and that the first host device and the second host device each transmit or receive packets via ports within a first link aggregation group (LAG). In response to determining that the first host device and the second host device each transmit or receive packets via ports within the first LAG, the first host device transmits the first packet from a first synchronization port of the first host device to a second synchronization port of the second host device. The first and second synchronization ports are excluded from sharing a common LAG with any ports of another host device.

    Abstract: The disclosure herein describes an edge device of a network for distributed policy enforcement. During operation, the edge device receives an initial packet for an outgoing traffic flow, and identifies a policy being triggered by the initial packet. The edge device performs a reverse lookup to identify at least an intermediate node that is previously traversed by the initial packet and traffic parameters associated with the initial packet at the identified intermediate node. The edge device translates the policy based on the traffic parameters at the intermediate node, and forwards the translated policy to the intermediate node, thus facilitating the intermediate node in applying the policy to the traffic flow.
