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.

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: An example provides a method of creating an instance of a virtual machine in a cloud computing system that includes: accepting a network connection at a server resource in the cloud computing system from a first client resource in a first virtualized computing system to transfer a first virtual machine; receiving first signatures for guest files of the first virtual machine from the first client resource; checking the first signatures against a content library in the cloud computing system to identify first duplicate files of the guest files that match first base files stored in the content library, and to identify first unique files of the guest files; instructing the first client resource such that a response to the instructing will send the first unique files to the exclusion of the first duplicate files; and generating an instance of the first virtual machine in the cloud computing system having the first base files and the first unique files.

Abstract: One or more examples provide a method of transferring a virtual machine between a virtualized computing system and a cloud computing system that includes: establishing connection between a first resource in the virtualized computing system and a second resource in the cloud computing system to transfer files that implement the virtual machine from the first resource to the second resource; accessing, for transmission over the connection, data blocks on a storage device in the virtualized computing system that include the files; executing at least one compliance check on each of the data blocks using at least one compliance checker; and preventing each of the data blocks that fails a compliance check from being maintained in the cloud computing system.

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: Some embodiments provide a novel method for load balancing data messages that are sent by a source compute node (SCN) to one or more different groups of destination compute nodes (DCNs). In some embodiments, the method deploys a load balancer in the source compute node's egress datapath. This load balancer receives each data message sent from the source compute node, and determines whether the data message is addressed to one of the DCN groups for which the load balancer spreads the data traffic to balance the load across (e.g., data traffic directed to) the DCNs in the group. When the received data message is not addressed to one of the load balanced DCN groups, the load balancer forwards the received data message to its addressed destination. On the other hand, when the received data message is addressed to one of load balancer's DCN groups, the load balancer identifies a DCN in the addressed DCN group that should receive the data message, and directs the data message to the identified DCN.

Abstract: Some embodiments provide novel inline switches that distribute data messages from source compute nodes (SCNs) to different groups of destination service compute nodes (DSCNs). In some embodiments, the inline switches are deployed in the source compute nodes datapaths (e.g., egress datapath). The inline switches in some embodiments are service switches that (1) receive data messages from the SCNs, (2) identify service nodes in a service-node cluster for processing the data messages based on service policies that the switches implement, and (3) use tunnels to send the received data messages to their identified service nodes. Alternatively, or conjunctively, the inline service switches of some embodiments (1) identify service-nodes cluster for processing the data messages based on service policies that the switches implement, and (2) use tunnels to send the received data messages to the identified service-node clusters.

Abstract: Some embodiments of the invention provide a novel method for specifying firewall rules. In some embodiments, the method provides the ability to specify for a particular firewall rule, a set of network nodes (also called a set of enforcement points below) at which the particular firewall should be enforced. To provide this ability, the method of some embodiments adds an extra tuple (referred to below as the AppliedTo tuple) to a firewall rule. This added AppliedTo tuple lists the set of enforcement points at which the firewall rule has to be applied (i.e., enforced).

Abstract: Some embodiments provide a network system. The network system includes a first set of host machines hosting virtual machines that connect to each other through a logical network. The network system includes a second set of host machines hosting virtualized containers that operate as gateways to process packets entering the logical network from external sources. Each of the virtualized containers advertises itself to an external router as a next hop for packets entering the logical network such that the external router uses equal-cost multi-path forwarding to distribute the packets across the virtualized containers on the second set of host machines.

Abstract: The disclosure herein describes an edge device of a network for distributed policy enforcement. During operation, the edge device receives an initial packet for an outgoing traffic flow, and identifies a policy being triggered by the initial packet. The edge device performs a reverse lookup to identify at least an intermediate node that is previously traversed by the initial packet and traffic parameters associated with the initial packet at the identified intermediate node. The edge device translates the policy based on the traffic parameters at the intermediate node, and forwards the translated policy to the intermediate node, thus facilitating the intermediate node in applying the policy to the traffic flow.
