Patent number: 11895188Abstract: A distributed, web-services based storage system. A system may include a web services interface configured to receive, according to a web services protocol, a given client request for access to a given data object, the request including a key value corresponding to the object. The system may also include storage nodes configured to store replicas of the objects, where each replica is accessible via a respective unique locator value, and a keymap instance configured to store a respective keymap entry for each object. For the given object, the respective keymap entry includes the key value and each locator value corresponding to replicas of the object. A coordinator may receive the given client request from the web services interface, responsively access the keymap instance to identify locator values corresponding to the key value and, for a particular locator value, retrieve a corresponding replica from a corresponding storage node.Type: GrantFiled: July 15, 2022Date of Patent: February 6, 2024Assignee: Amazon Technologies, Inc.Inventors: Allan Henry Vermeulen, Alan B. Atlas, David M. Barth, John David Cormie, Ami K. Fischman, James Christopher Sorenson, III, Eric M. Wagner

Patent number: 10652076Abstract: Dynamic application instance discovery and state management within a distributed system. A distributed system may implement application instances configured to perform one or more application functions within the distributed system, and discovery and failure detection daemon (DFDD) instances, each configured to store an indication of a respective operational state of each member of a respective group of the number of application instances. Each of the DFDD instances may repeatedly execute a gossip-based synchronization protocol with another one of the DFDD instances, where execution of the protocol between DFDD instances includes reconciling differences among membership of the respective groups of application instances. A new application instance may be configured to notify a particular DFDD instance of its availability to perform an application function.Type: GrantFiled: December 4, 2017Date of Patent: May 12, 2020Assignee: Amazon Technologies, Inc.Inventors: John David Cormie, Ami K.
