Abstract: Embodiments include determining computing resources within one or more data centers onto which a virtual workload can be deployed. Network state data is determined for a plurality of network resources within a network fabric of a data center. For each of the plurality of computing resources, embodiments determine a respective suitability value describing a fitness of the respective physical server for deploying at least a portion of the virtual workload. Such a determination includes determining a respective at least one of the plurality of network resources within the at least one network fabric corresponding to the respective computing resource and determining a current workload of the at least one network resource, based on the network state data. Upon selecting one or more computing resources of the plurality of computing resources based on the determined suitability values, embodiments deploy the virtual workload onto the selected one or more computing resources.

Abstract: Techniques are disclosed for configuring a LISP mobility network. A management tool receives a configuration for a network fabric. The configuration specifies values for one or more attributes associated with a Locator ID Separation Protocol (LISP)-enabled network. The management tool generates one or more commands based on the specified values for the one or more attributes associated with the LISP-enabled network. The generated commands are distributed to a plurality of network devices in the network fabric. Each network device executes the one or more commands to configure the network fabric.

Abstract: Techniques for virtual workload deployment based on computing resource hardware load and associated network hardware load. For each of a plurality of computing resources within one or more data centers onto which a virtual workload can be deployed, a computing resource hardware load of the respective computing resource is determined. Network topology information is maintained for at least one network fabric of the one or more data centers, and an associated network hardware load of a network device communicatively connected to the respective computing resource is determined. Embodiments automatically select one or more computing resources. The virtual workload is deployed onto the automatically selected one or more computing resources.

Abstract: In one embodiment, a method for improving routing for a stretched subnet includes receiving a first communication on a border leaf of the stretched subnet, where the border leaf is a top of rack (ToR) switch configured to facilitate connectivity between an internal data center fabric and at least one external site associated with the stretched subnet, based on routing information received with the received communication, identifying a source address for the received communication as either from within the internal data center fabric or from the at least one external site, and if the source address is from the external site, storing an abbreviated route based on the source address in at least one hardware table, where the abbreviated route is a route to the at least one external site, and upon subsequent receipt of a second communication to be forwarded to the source address, forwarding the second communication in accordance with the abbreviated route.
