Abstract: Techniques for creating layer 2 (L2) extension networks are disclosed. One embodiment permits an L2 extension network to be created by deploying, configuring, and connecting a pair of virtual appliances in the data center and the cloud so that the appliances communicate via secure tunnels and bridge networks in the data center and the cloud. A pair of virtual appliances are first deployed in the data center and the cloud, and secure tunnels are then created between the virtual appliances. Thereafter, a stretched network is created by connecting a network interface in each of the virtual appliances to a respective local network, configuring virtual switch ports to which the virtual appliances are connected as sink ports that receive traffic with non-local destinations, and configuring each of the virtual appliances to bridge the network interface therein that is connected to the local network and tunnels between the pair of virtual appliances.

Abstract: A method of migrating a virtualized computing instance between source and destination virtualized computing systems includes executing a first migration workflow in the source virtualized computing system between a source host computer and a first mobility agent simulating a destination host, executing a second migration workflow in the destination virtualized computing system between a second mobility agent simulating a source host and a destination host computer, sending, as part of the first migration workflow, a configuration of the migrated virtualized computing instance to the destination virtualized computing system, translating, as part of the second migration workflow, infrastructure-dependent information in the configuration of the migrated virtualized computing instance, and transferring, during execution of the first and second migration workflows, migration data including the virtualized computing instance between the source host and the destination host over a network.

Abstract: Techniques for upgrading virtual appliances in a hybrid cloud computing system are provided. In one embodiment, virtual appliances are upgraded by deploying the upgraded appliances in both a data center and a cloud, configuring the upgraded appliances to have the same IP addresses as original appliances, and disconnecting the original appliances from networks to which they are connected and connecting the upgraded appliances to those networks via the same ports previously used by the original appliances. In another embodiment, upgraded appliances are deployed in the data center and the cloud, but configured with new IP addresses that are different from those of the original appliances, and connections are switched from those of the original appliances to new connections with the new IP addresses. Embodiments disclosed herein permit virtual appliances to be upgraded or replaced with relatively little downtime so as to help minimize disruptions to existing traffic flows.

Abstract: Some embodiments provide a method that generating a host profile for deploying a first network function. the method uses a virtual machine configuration operator in a remote data center to configure one or more virtual machines implementing a workload cluster to perform the first network function based on the host profile. The method uses the virtual machine configuration operator to configure one or more virtual machines implementing a management cluster based on the host profile. The workload cluster is managed by the management cluster.

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 fleet manager within a cloud computing system utilizes a registration framework with one or more cloud infrastructure managers having corresponding infrastructure data plane nodes, which may be in use by different tenants. Instead of having the infrastructure managers communicate directly with its corresponding infrastructure data plane nodes via a management network or domain, the fleet manager communicates with infrastructure managers and relay commands, instructions, and other payloads to the infrastructure data plane nodes using a virtual machine (VM) communication backchannel.

Abstract: A computer-implemented method, medium, and system for upgrade of telco node cluster running cloud-native network functions are disclosed. In one computer-implemented method, a worker node group that includes a plurality of worker nodes is determined in a container orchestration platform. A first node to upgrade is determined within the worker node group. All pods in the first node are deactivated by a high availability as a service (HAaaS) module. Standby pods in a second node are activated by the HAaaS module and as active pods. All network traffic associated with all the pods in the first node is migrated to the active pods. The first node is deleted from the worker node group. Hardware resources associated with running the first node are released. A third node is generated as a new worker node in the worker node group and uses the released hardware resources.
