  • Patent number: 10735452
    Abstract: A method of transferring a virtual machine between a virtualized computing system and a cloud computing system includes determining that a virtual machine is to be transferred from a virtualized computing system to a cloud computing system and determining a connection between a first resource in the virtualized computing system and a second resource in the cloud computing system. Files that enable implementation of the virtual machine at the virtualized computing system and identified, as are file portions of the files for transfer from the virtualized computing system to the cloud computing system. At least one compliance check is executed on each of the file portions using at least one compliance checker. Each of the file portions that fails a compliance check is blocked from being maintained in the cloud computing system.

  • Patent number: 10721098
    Abstract: Connectivity between data centers in a hybrid cloud system having a first data center managed by a first organization and a second data center managed by a second organization, the first organization being a tenant in the second data center, is optimized. According to the described technique, a path-optimized connection is established through a wide area network (WAN) between a first gateway of a first data center and a second gateway of a second data center for an application executing in the first data center based on performance of paths across a set of Internet Protocol (IP) flows. Application packets received from the application at the first gateway are forwarded to a WAN optimization appliance in the first data center. WAN optimized application packets received from the WAN optimization appliance at the first gateway are then sent to the second gateway over the path-optimized connection.

  • Patent number: 10721161
    Abstract: An example method of optimizing connectivity between data centers in a hybrid cloud system having a first data center managed by a first organization and a second data center managed by a second organization, the first organization being a tenant in the second data center. The method includes probing a wide area network (WAN) with test packets by varying an internet protocol (IP) flow tuple of the test packets across a set of IP flows. The method includes identifying a plurality of paths between a gateway of the first data center and another gateway of the second data center associated with the set of IP flows. The method further includes selecting an IP flow from the set of IP flows for an application executing in the first data center. The method further includes establishing a path-optimized connection between the gateway and the other gateway through the WAN having the selected IP flow for use by the application.

  • Publication number: 20200220767
    Abstract: Some embodiments provide a network system that includes several host machines for hosting virtual machines, divided into several different domains. The network system includes several local domain management servers. A first local domain management server of a first domain is for (i) initiating creation of a set of distributed virtual switch ports associated with a particular logical network identifier on a host machine within its domain and (ii) attaching a first virtual machine on the host machine to a created port associated with the particular logical network identifier in order for the first virtual machine to send traffic over the logical network. The network system includes a second level management server for coordinating the use of logical network identifiers between multiple different logical domain management servers in order for the first virtual machine to communicate via the logical network with a second virtual machine in a second domain.

  • Patent number: 10666729
    Abstract: An approach is disclosed for steering network traffic away from congestion hot-spots to achieve better throughput and latency. In one embodiment, multiple Foo-over-UDP (FOU) tunnels, each having a distinct source port, are created between two endpoints. As a result of the distinct source ports, routers that compute hashes of packet fields in order to distribute traffic flows across network paths will compute distinct hash values for the FOU tunnels that may be associated with different paths. Probes are scheduled to measure network metrics, such as latency and liveliness, of each of the FOU tunnels. In turn, the network metrics are used to select particular FOU tunnel(s) to send traffic over so as to avoid congestion and high-latency hotspots in the network.

  • Patent number: 10530650
    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.

  • Patent number: 10505806
    Abstract: Techniques disclosed herein permit logical topologies of datacenters to be automatically learned and re-created in the cloud. In one embodiment, a datacenter landscape is determined based on numbers of hops from nodes in a datacenter to a wide area network (WAN)-facing node. Such a datacenter landscape may then be re-created in the cloud. In another embodiment, virtual appliances are deployed using templates with user-tunable parameters. What would have been set up manually in a physical datacenter, such as connecting a new router to other devices, is then simplified to adjusting parameters of the template to specify, e.g., that the router is a routed hop rather than a bump in the wire, with the router then being automatically deployed in the specified manner.

  • Publication number: 20190361734
    Abstract: Techniques disclosed herein relate to migrating virtual computing instances such as virtual machines (VMs). In one embodiment, VMs are migrated across different virtual infrastructure platforms by, among other things, translating between resource models used by virtual infrastructure managers (VIMs) that manage the different virtual infrastructure platforms. VM migrations may also be validated prior to being performed, including based on resource policies that define what is and/or is not allowed to migrate, thereby providing compliance and controls for borderless data centers. In addition, an agent-based technique may be used to migrate VMs and physical servers to virtual infrastructure, without requiring access to an underlying hypervisor layer.

  • Publication number: 20190364099
    Abstract: A hybrid cloud computing system having a private data center and a public cloud computing system is discussed. The private data center is managed by a first organization. The public cloud computing system is managed by a second organization, and the first organization is a tenant in the public cloud computing system. The hybrid cloud computing system is configured to generate a mapping that contextualizes virtual objects migrated between the private data center and the public cloud computing system based on the objects' location. Such a mapping is maintained to expose the true hybridity of the hybrid cloud rather than present two distinct views of a private data center (or private cloud) and a public cloud.

  • Patent number: 10382532
    Abstract: A method for managing an application executing in a computing system is disclosed as including a private cloud operated by a first organization and a multi-tenant public cloud of which the first organization is one of the tenants. The method comprises instantiating a first virtual object in the private cloud and instantiating a second virtual object in the public cloud for executing the application cooperatively with the first virtual object. Mapping associated with the first virtual object is generated, wherein the mapping comprises a first identifier having a context of the private cloud and a second identifier having a context of the public cloud. The method further includes detecting migration of the first or second virtual object such that both of the first and second virtual objects are instantiated in a single one of the private and public clouds and updating the mapping to reflect the migration.
