US 11,115,473 B2 · Redundant storage gateways

Abstract

Methods, apparatus, and computer-accessible storage media for providing redundant storage gateways. A client may create a storage gateway group and add storage gateways to the group. The client may assign one or more volumes on a remote data store to each the storage gateways in the group. Volume data for each storage gateway in the group may be replicated to at least one other storage gateway in the group. If one of the gateways in the group becomes unavailable, one or more other gateways in the group may take over volumes previously assigned to the unavailable gateway, using the replicated data in the group to seamlessly resume gateway operations for the respective volumes. Client processes that previously communicated with the unavailable gateway may be manually or automatically directed to the gateway(s) that are taking over the unavailable gateway's volumes.

Claims20

Dependent claims

A system, comprising:

a data store on a provider network of a service provider that provides a storage service to clients on a plurality of client networks via one or more storage gateways on each of the client networks, wherein the storage gateways on the client networks act as interfaces, between one or more client processes on the client networks and the storage service, to access client data maintained on the data store by the storage service, and wherein for a particular client network comprising a group of redundant storage gateways, the data store is configured with respective volumes for each storage gateway of the group of redundant storage gateways;
and
one or more processors and memory storing program instructions that implement a gateway control of the provider network configured to manage relationships between the respective volumes and the group of redundant storage gateways on the particular client network.

A method, comprising:

receiving, by a gateway control on a network of a service provider that provides storage service to clients on a plurality of client networks via one or more storage gateways on the client networks, messages from one or more storage gateways of a group of redundant storage gateways on a particular client network, wherein the storage gateways on the client networks act as interfaces between one or more client processes on the client networks and the storage service to access client data maintained on a data store by the storage service;
and
managing, by a gateway control and based at least in part on the received messages, relationships between one or more volumes of the data store and the group of redundant storage gateways on the particular client network.

One or more non-transitory computer-readable media storing program instructions that when executed on or across one or more processors implement a gateway control, the gateway control configured to perform:

processing messages received over a network from one or more storage gateways of a group of redundant storage gateways on a particular client network, wherein the storage gateways on the particular client network act as interfaces between one or more client processes on the particular client network and a storage service to access client data maintained on a data store by the storage service;
and
managing, based at least in part on the received messages, the group of redundant storage gateways on the particular client network.
