Abstract: An example method for a programmable infrastructure gateway for enabling hybrid cloud services in a network environment is provided and includes receiving an instruction from a hybrid cloud application executing in a private cloud, interpreting the instruction according to a hybrid cloud application programming interface, and executing the interpreted instruction in a public cloud using a cloud adapter. The method is generally executed in the infrastructure gateway including a programmable integration framework allowing generation of various cloud adapters using a cloud adapter software development kit, the cloud adapter being generated and programmed to be compatible with a specific public cloud platform of the public cloud. In specific embodiments, identical copies of the infrastructure gateway can be provided to different cloud service providers who manage disparate public cloud platforms; each copy of the infrastructure gateway can be programmed differently to generate corresponding cloud adapters compatible with the respective public cloud platforms.

Abstract: Aspects of the instant disclosure relate to methods for facilitating intercloud resource migration. In some embodiments, a method of the subject technology can include steps for instantiating a first intercloud fabric provider platform (ICFPP) at a first cloud datacenter, instantiating a second ICFPP at a second cloud datacenter, and receiving a migration request at the first ICFPP, the migration request including a request to migrate a virtual machine (VM) workload from the first cloud datacenter to the second cloud datacenter. In some aspects, the method may further include steps for initiating, by the first ICFPP, a migration of the VM workload via the second ICFPP in response to the migration request. Systems and machine readable media are also provided.

Abstract: According to one aspect, a method includes an Intercloud Fabric Switch (ICS) included in a public cloud and an ICS cluster obtaining a packet, and determining if the packet is obtained from a site-to-site link that links the ICS to an enterprise datacenter. If the packet is obtained from the site-to-site link, it is determined whether the packet is an unknown unicast packet. If the packet is an unknown unicast packet, the packet is dropped, and if not, the packet is provided to an access link that links the ICS to a virtual machine. If the packet is not obtained from the site-to-site link, it is determined whether the packet is obtained from an inter-ICS link that allows the ICS to communicate with the ICS cluster. If the packet is obtained from the inter-ICS link, the packet is dropped if it is an unknown unicast packet.

Abstract: Network policies can be used to optimize the flow of network traffic between virtual machines (VMs) in a hybrid cloud environment. In an example embodiment, one or more policies can drive a virtual switch controller, a hybrid cloud manager, a hypervisor manager, a virtual switch, or other orchestrator to create one or more direct tunnels that can be utilized by a respective pair of VMs to bypass the virtual switch and enable direct communication between the VMs. The virtual switch can send the VMs network and security policies to ensure that these policies are enforced. The VMs can exchange security credentials in order to establish the direct tunnel. The direct tunnel can be used by the VMs to bypass the virtual switch and allow the VMs to communicate with each other directly.

Abstract: Presented herein are service-function chaining techniques. In one example, a service controller in a network comprising a plurality of service nodes receives one is configured to identify one or more service-functions hosted by each of the service nodes. The service controller defines a service-function chain in terms of service-functions to be applied to traffic in the network and provides information descriptive of the service-function chain to a classifier node.

Abstract: A highly scalable application network appliance is described herein. According to one embodiment, a network element includes a switch fabric, a first service module coupled to the switch fabric, and a second service module coupled to the first service module over the switch fabric. In response to packets of a network transaction received from a client over a first network to access a server of a data center having multiple servers over a second network, the first service module is configured to perform a first portion of OSI (open system interconnection) compatible layers of network processes on the packets while the second service module is configured to perform a second portion of the OSI compatible layers of network processes on the packets. The first portion includes at least one OSI compatible layer that is not included in the second portion. Other methods and apparatuses are also describe.

Abstract: An example method for service node originated service chains in a network environment is provided and includes receiving a packet at a service node in a network environment that includes a plurality of service nodes and a central classifier, analyzing the packet for a service chain modification or a service chain initiation, classifying the packet at the service node to a new service chain based on the analysis, initiating the new service chain at the service node if the analysis indicates service chain initiation, and modifying an existing service chain for the packet to the new service chain if the analysis indicates service chain modification. In specific embodiments, the analysis includes applying classification logic specific to the service node. Some embodiments, service node attributes and order of service nodes in substantially all service chains configured in the network may be received from a central controller.

Abstract: Presented herein are techniques for dynamic creation of a unique service path for a service chain. In one example, a service controller and a plurality of service nodes are provided, each service node configured to apply a service function to traffic that passes through the respective service node. The service controller defines a service chain identifying a set of service functions and an order in which they are applied. The service controller receives an indication that the service chain has been instantiated at a classifier, and creates a unique service path for the service chain, wherein the unique service path includes the service chain and the classifier at which the service chain is instantiated.

Abstract: Many hybrid cloud topologies require virtual machines in a public cloud to use a router in a private cloud, even when the virtual machine is transmitting to another virtual machine in the public cloud. Routing data through an enterprise router on the private cloud via the internet is generally inefficient. This problem can be overcome by placing a router within the public cloud that mirrors much of the routing functionality of the enterprise router. A switch configured to intercept address resolution protocol (ARP) request for the enterprise router's address and fabricate a response using the MAC address of the router in the public cloud.
