Abstract: Techniques for performing network address allocation, administration and management in federated cloud computing networks are described. In one example embodiment, network interface cards (NICs) in a local network services appliance and a remote network services appliance register with an associated local network cloud and remote network cloud in the federated cloud computing networks. The local cloud network and the remote cloud network are then configured to send packets with unclaimed network address to the associated registered NICs. A layer-2 (L2) network tunnel including a data channel and a control channel is then formed between the local network services appliance and the remote network services appliance by stitching the local cloud network and the remote cloud network. Network address allocation, administration and management in the federated cloud computing networks are then performed using the formed L2 network tunnel.

Abstract: Techniques are disclosed for deploying and maintaining appliances in a hybrid cloud computing system which includes an on-premise data center and a public cloud computing system configured to provide a common platform for managing and executing virtual workloads. Appliances to be deployed may include those required (or useful) for hybrid operations, including a cloud gateway appliance, a wide area network (WAN) optimizer, a layer 2 (L2) concentrator, and a mobility agent that handles virtual machine (VM) migration traffic. Such appliances are deployed first on the on-premise data center, and remote jobs are then sent to the public cloud to deploy the same appliances thereon. After deployment, the appliances deployed on the on-premise data center and corresponding appliances on the public cloud share configuration states and may further be wired together to communicate via secure encrypted tunnels.

Abstract: Techniques for dynamic configuration of a domain name system (DNS) server in a virtual network environment are described. In one example embodiment, DNS rules are configured using virtual machine (VM) inventory objects and associated DNS names. Further, the configured DNS rules are transformed by replacing the VM inventory objects in the configured DNS rules with associated Internet protocol (IP) addresses using an IP address management (IPAM) table or a network address translation (NAT) table and the DNS names in the configured DNS rules with modified DNS names using a zone table and a view table. Furthermore, the transformed DNS rules are sent to the DNS server for performing domain name resolutions associated with multiple VMs running on a plurality of host computing systems in a computing 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 method is provide for managing a migration of a virtual machine from a private data center managed by a first organization to a public cloud computing system by a second organization and where the first organization is a tenant. The configurations of physical infrastructure of the private data center that underlies the virtual machine are determined, along with a corresponding match preference indicating a level of criticality for some corresponding configuration at the public cloud system. The configurations and match preferences generated as part of a migration package. The public cloud computing system instantiates a corresponding VM based on the determined configurations and corresponding match preferences.

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: Techniques for dynamically configuring a dynamic host configuration protocol (DHCP) server in a virtual network environment are described. In one example embodiment, DHCP bindings are configured using virtual machine (VM) inventory objects. Further, the configured DHCP bindings are transformed by replacing the VM inventory objects in the configured DHCP bindings with associated media access control (MAC) addresses using a VM object attribute table. Furthermore, the transformed DHCP bindings are sent to the DHCP sever for assigning Internet protocol (IP) addresses to multiple VMs running on a plurality of host computing systems in a computing network.

Abstract: Techniques for dynamic configuration of a load balancer in a virtual network environment are described. In one example embodiment, load balancing rules are configured using virtual machine (VM) inventory objects. The configured load balancing rules are then transformed by replacing the VM inventory objects in the configured load balancing rules with associated Internet protocol (IP) addresses using an IP address management (IPAM) table or a network address translation (NAT) table. The transformed load balancing rules are then sent to the load balancer for load balancing network traffic between a plurality of VMs running on one or more host computing systems in one or more computing networks.

Abstract: Techniques for automatic firewall configuration in a virtual network environment are described. In one example embodiment, firewall rules are configured using virtual machine (VM) inventory objects. The firewall rules are then transformed by replacing the VM inventory objects in the configured firewall rules with associated Internet protocol (IP) addresses using an IP address management table (IPAM) table and a network address translation (NAT) table. The transformed firewall rules are then sent to a firewall engine for filtering communication from and to VMs running on a first machine on one or more computing networks and communication from and to VMs running on a second machine on one or more computing networks at a firewall according to the transformed firewall rules.
