  • 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: 10992521
    Abstract: A storage gateway serves as an interface between processes on a customer network and a service provider. The storage gateway is located on-premise with the customer processes. To customer processes, it appears that data is stored locally. However, the storage gateway interfaces with a remote storage service to store the data. For cached gateways, the primary data store is a remote data store, while frequently accessed data may be locally cached by the gateway. Reads may be satisfied from the local cache or from virtual data storage; writes are handled so as to appropriately update data blocks in the local cache and/or in virtual data storage. For shadowing gateways, the primary data store is the local data store; reads are passed through to a local data store, and writes are shadowed to virtual data storage as well as being sent to local data store.

  • Patent number: 10735499
    Abstract: A control-plane component of a virtual network interface (VNI) multiplexing service assigns one or more VNIs as members of a first interface group. A first VNI of the interface group is attached to a first compute instance. Network traffic directed to a particular endpoint address associated with the first interface group is to be distributed among members of the first interface group by client-side components of the service. The control-plane component propagates membership metadata of the first interface group to the client-side components. In response to a detection of an unhealthy state of the first compute instance, the first VNI is attached to a different compute instance by the control-plane component.

  • Patent number: 10536520
    Abstract: Methods, apparatus, and computer-accessible storage media for shadowing data stored on a local store to a remote store provided by a service provider. A gateway may be configured as a shadowing gateway on a customer network in response to receiving configuration information. The shadowing gateway may receive reads and writes to the local store. The gateway passes the requests to the local store, and also uploads write data indicated by the writes to the service provider to update a snapshot of the local store maintained by the service provider on the remote store. The write data may be buffered to a write log for uploading, and may be uploaded as blocks according to a block storage format used by the service provider. The shadowing process may be transparent to processes on the customer network. The shadowed data may be used to recover data on the local store.

  • Patent number: 10474632
    Abstract: Methods and apparatus for secure data modification using segmented hashing are disclosed. An intermediate device on a data path between a storage service and a client receives a modification request for a data segment of a data chunk of a storage object. The device generates a new chunk hash value for the chunk based on an original chunk hash value of the chunk, an original segment hash value of the segment to be modified, and a new segment hash value computed based on the modification. The device generates a modified version of the chunk based on the modification request, and uploads the modified version and the new chunk hash value to the storage service.

  • Patent number: 10027712
    Abstract: Embodiments may include a load balancer that receives a request packet sent by a remote client to an original destination address of multiple network addresses serviced by the load balancer, and selects according to a load balancing protocol, a host computer of a plurality of host computers to process the request. The load balancer may, from among a plurality of ports on the selected host computer, select a particular port having a one-to-one association with the original destination address, the association specified by mapping information accessible to the load balancer, and send the request packet to the selected port on the selected host computer. The mapping information accessible to the selected host computer specifies a one-to-one association between the selected port and the original destination address. Sending the request packet to the selected port conveys that address to the selected server without that address being included in that packet.

  • Publication number: 20180196827
    Abstract: Methods, apparatus, and computer-accessible storage media for controlling export of snapshots to external networks in service provider environments. Methods are described that may be used to prevent customers of a service provider from downloading snapshots of volumes, such as boot images created by the service provider or provided by third parties, to which the customer does not have the appropriate rights. A request may be received from a user to access one or more snapshots, for example a request to export the snapshot or a request for a listing of snapshots. For each snapshot, the service provider may determine if the user has rights to the snapshot, for example by checking a manifest for the snapshot to see if entries in the snapshot manifest belong to an account other than the customer's. If the user has rights to the snapshot, the request is granted; otherwise, the request is not granted.

  • Publication number: 20180152501
    Abstract: Methods, apparatus, and computer-accessible storage media for remotely managing a gateway that serves as an interface between processes on a customer network and a service provider, for example to store data to a remote data store. The gateway sends a connection request to a gateway control server. The server holds the connection until the server receives information (e.g., information from the customer sent via the service provider) for the gateway. The server sends the information as requests via the gateway-initiated connection, and continues to hold the connection. If a server receives information for a gateway to which it does not hold a connection, the server sends the information to the server that does hold the connection. The server may either discover the appropriate server via a registration service that registers connections to gateways or broadcast the information to peer servers identified through a registration service.
