A distributed computing system is provided, including a source computing device implementing a source hypervisor executing a virtual machine, a source-side router coupled to the source hypervisor, a destination computing device implementing a destination hypervisor, and a destination-side router coupled to the destination hypervisor. The source hypervisor is connected to the destination hypervisor through a network. During a migration of the virtual machine from the source hypervisor to the destination hypervisor, the source-side router duplicates packets ingressing into the source-side router. The duplicated packets include a first set of packets and a second set of packets, where the first set of packets is routed to the virtual machine through the source hypervisor on the network, and the second set of packets is routed to the virtual machine through the destination hypervisor on the network.

A distributed computing system is provided, including a server executing a mobility service, and a first computing device executing a first hypervisor implementing a first mobility client configured to detect an attachment of a virtual machine to the first hypervisor, and a second computing device executing a second hypervisor implementing a second mobility client configured to detect an attachment of the virtual machine to the second hypervisor, and send a message to the first computing device indicating the attachment of the virtual machine to the second hypervisor. The first mobility client is further configured to store network routing information indicating a network location of the virtual machine, receive network traffic for the virtual machine, and forward the network traffic to the second hypervisor based on the stored network routing information.

Systems and methods for enabling access to dedicated resources in a virtual network using top of rack switches are disclosed. A method includes a virtual filtering platform encapsulating at least one packet, received from a virtual machine, to generate at least one encapsulated packet comprising a virtual network identifier (VNI). The method further includes a TOR switch: (1) receiving the at least one encapsulated packet and decapsulating the at least one encapsulated packet to create at least one decapsulated packet, (2) using the VNI to identify a virtual routing and forwarding artifact to determine a virtual local area network interface associated with the dedicated hardware portion, and (3) transmitting the at least one decapsulated packet to the dedicated hardware portion based on at least one policy provided by a controller, where the at least one policy comprises information related to a customer of the service provider.

Enabling access to dedicated resources in a virtual network using top of rack switches

A request to resolve an IP address is received by a Domain Name Server (DNS). A record, such as an MX record, relating to the request is obtained that comprises a unique label (e.g. record=customer-com.mail.messaging.com) that is used in determining how to resolve the request. The unique label portion of the record (e.g. customer-com) is used to identify information relating to the request such as a version of software/service to use to handle the request, a region used to handle the request, and the like. The same record may be used to direct a request to a different version and/or different region. For example, without changing the record, a request at one time may access a first version/region and a request at a different time access a different version/region.
