    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.

    Abstract: Methods and apparatus for intelligent cache eviction at storage gateways are disclosed. A system comprises computing devices configured to determine whether the number of free chunks of storage at a storage appliance for caching portions of a storage object is below a threshold value. If the number is below the threshold, the computing devices identify an eviction set of chunks to be freed, and generate a respective new instance identifier for each chunk of the eviction set. The identifier of a given chunk may be used to determine a validity of a block of the chunk. The devices store, within metadata storage of the appliance, the new instance identifiers of the eviction set, and indicate that the chunks of the eviction set are available for caching data of the storage object.

    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.

    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.

    Abstract: Methods, apparatus, and computer-accessible storage media for activating a gateway to a remote service provider. The gateway serves as an interface between processes on a customer network and the provider, for example to store customer data to a remote data store. A gateway sends a public key and metadata describing the gateway to the provider. The gateway receives an activation key from the provider and exposes the activation key on the customer network. The customer obtains the key and communicates to the provider using the key to provide customer information including a name for the gateway and to authorize registration of the gateway. The provider provides the customer information to the gateway. The gateway requests security credentials from the provider using the customer information and the key. The provider sends a security credential to the gateway. The gateway may then obtain configuration information from the customer via the provider.
