  • Patent number: 11709698
    Abstract: A method of deploying a network service (NS) across multiple data centers includes identifying virtual network functions (VNFs) associated with the NS in response to a request for or relating to the NS, generating commands to deploy VNFs based on VNF descriptors, and issuing the commands to the data centers to deploy VNFs. The data centers each have a cloud management server in which cloud computing management software is run to provision virtual infrastructure resources thereof for a plurality of tenants. The cloud computing management software of a first data center is different from the cloud computing management software of a second data center, and the commands issued to the first and second data centers are each a generic command that is not in a command format of the cloud computing management software of either the first data center or the second data center.

  • Patent number: 11372664
    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.

  • Patent number: 11095709
    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: 11070520
    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: 10757170
    Abstract: Conditional address translation is performed in a multi-tenant cloud infrastructure to effectively support tenant-assigned addresses. For each tenant, the multi-tenant cloud infrastructure deploys both a private network used to communicate between the tenant and the cloud and a tenant-facing gateway to manage the private network. The multi-tenant cloud infrastructure also includes an externally-facing gateway used to communicate between the multi-tenant cloud and a public network. The tenant-facing gateways are configured to bypass address translation—providing consistent addressing across each private network irrespective of the physical location of resources linked by the private network. By contrast, the public-facing gateway is configured to translate source addresses in outgoing packets to addresses that are unique within the public network.
