  • Publication number: 20220197683
    Abstract: Aspects of the present application relate to systems, methods and non-transitory computer readable media for network virtualization in a rack-based switch. The method can include sending a communication from a first virtual machine (“VM”) instantiated on a first host machine to a first network virtualization Top of Rack (“ToR”) switch. The first network virtualization ToR can include a peripheral component interconnect express (“PCIe”) switch coupled to a plurality of host-side Ethernet ports, a virtualization device communicatingly coupled to the PCIe switch, which virtualization device can include a plurality of virtualization functions, and a switching ASIC coupled to the virtualization device and to a network-side Ethernet port. The method can include forming the communication into an Internet Protocol (“IP”) packet with a first virtualization function of the virtualization device, and sending the IP packet to a second VM with the switching ASIC.

  • Publication number: 20220200801
    Abstract: A network interface card, such as a SmartNIC, is used to provide encryption, such as network encryption virtual function (NEVF), for a virtual machine, so that a customer can control network keys in a virtual cloud network. The NEVF includes a memory device (e.g., SRAM) and a crypto processor (e.g., a crypto core). The memory device stores a crypto key. The crypto processor uses the crypto key to encrypt data to and from a virtual machine in the virtual cloud network. A key management system can be used to securely transfer crypto keys to the NEVF. Having one NEVF per virtual machine can enable a customer to manage the crypto key for a virtual cloud network.

  • Publication number: 20220200972
    Abstract: For end-to-end encryption of a virtual cloud network, a VPN tunnel from a customer device is terminated at a host network headend device using encryption keys secured in hardware and managed by the customer. The network headend device can be a card in a bare-metal server with one or more network virtualization devices. The network headend device is configured to receive a first key provisioned by a customer; receive a first data packet sent from a device of the customer; and decrypt the first data packet using the first key to obtain information. A network virtualization device is configured to receive the information from the network headend device; ascertain that the information is to be sent to a virtual machine in a virtual cloud network; ascertain that data in the virtual cloud network is configured to be encrypted; and encrypt the information with a second key to generate a second data packet before routing the second data packet to the virtual machine.

  • Publication number: 20210373935
    Abstract: High-speed processing of packets to, and from, a virtualization environment can be provided while utilizing hardware-based segmentation offload and other such functionality. A hardware vendor such as a network interface card (NIC) manufacturer can enable the hardware to support open and proprietary stateless tunneling in conjunction with a protocol such as single root I/O virtualization (SR-IOV) in order to implement a virtualized overlay network. The hardware can utilize various rules, for example, that can be used by the NIC to perform certain actions, such as to encapsulate egress packets and decapsulate packets.

  • Patent number: 11128698
    Abstract: Processes and systems are disclosed for selecting a producer system from a number of producer systems to lease to a consumer system. A leasing agent, in response to a request from the consumer system for access to a service at a producer system, can identify a producer system to lease to the lease requestor based, at least in part, on a selection weight associated with each producer system that the leasing agent is assigned. The selection weights can be modified based on status information associated with each of the producer systems. This status information may be obtain from the producer systems and/or from a consumer system that has previously accessed the producer system. The consumer system may provide the status information to the leasing agent as part of the consumer system's lease request.

  • Patent number: 11068395
    Abstract: Methods and apparatus for supporting cached volumes at storage gateways are disclosed. A storage gateway appliance is configured to cache at least a portion of a storage object of a remote storage service at local storage devices. In response to a client's write request, directed to at least a portion of a data chunk of the storage object, the appliance stores a data modification indicated in the write request at a storage device, and asynchronously uploads the modification to the storage service. In response to a client's read request, directed to a different portion of the data chunk, the appliance downloads the requested data from the storage service to the storage device, and provides the requested data to the client.

  • Patent number: 10862762
    Abstract: Techniques for implementing a single-addressable virtual topology element (VTE) in a virtual topology. A VTE in a virtual topology may be distributed as multiple instantiated elements in a physical topology. However, the multiple instantiated elements are addressable as a single entity. Obtaining information associated with the VTE includes obtaining and aggregating information from each of the instantiated elements. Applying an overall configuration to the VTE includes determining a respective configuration for each instantiated element based on the overall configuration, and applying the respective configuration to each instantiated element.

  • Patent number: 10462033
    Abstract: Techniques for implementing a virtual tap in a virtual topology are described. A request to tap a particular link between a set of virtual topology entities (VTEs) is received. The particular link between the set of VTEs is mapped to a link between a set of instantiated entities in a physical topology. One of the instantiated elements implements a tapping function. Additionally or alternatively, a tapping element is instantiated and the tapping element implements the tapping function. The tapping element is not one of the set of instantiated entities. The tapping function includes: applying a tap filter to a set of data; replicating the data that passes the tap filter; and transmitting the replicated data to a virtual endpoint. The replicated data may be referred to as “tapped data.” A user interface engine presents information regarding the particular link between the set of VTEs based on the tapped data.

  • Patent number: 10452514
    Abstract: A set of techniques is described for monitoring and analyzing crashes and other malfunctions in a multi-tenant computing environment (e.g. cloud computing environment). The computing environment may host many applications that are executed on different computing resource combinations. The combinations may include varying types and versions of hardware or software resources. A monitoring service is deployed to gather statistical data about the failures occurring in the computing environment. The statistical data is then analyzed to identify abnormally high failure patterns. The failure patterns may be associated with particular computing resource combinations being used to execute particular types of applications. Based on these failure patterns, suggestions can be issued to a user to execute the application using a different computing resource combination.

  • Patent number: 10372685
    Abstract: A client request, formatted in accordance with a file system interface, is received at an access subsystem of a distributed multi-tenant storage service. After the request is authenticated at the access subsystem, an atomic metadata operation comprising a group of file system metadata modifications is initiated, including a first metadata modification at a first node of a metadata subsystem of the storage service and a second metadata modification at a second node of the metadata subsystem. A plurality of replicas of at least one data modification corresponding to the request are saved at respective storage nodes of the service.
