Patent number: 11842217Abstract: Mechanisms for resource isolation allow tenants executing in a multi-tenant software container to be isolated in order to prevent resource starvation by one or more of the tenants. Mechanisms for dependency isolation may be utilized to prevent one tenant executing in a multi-tenant software container from using another tenant in the same container in a manner that requires co-tenancy. Mechanisms for security isolation may be utilized to prevent one tenant in a multi-tenant software container from accessing protected data or functionality of another tenant. Mechanisms for fault isolation may be utilized to prevent tenants in a multi-tenant software container from causing faults or other types of errors that affect other tenants executing in the same software container.Type: GrantFiled: July 29, 2021Date of Patent: December 12, 2023Assignee: Amazon Technologies, Inc.Inventors: Keian Christopher, Kevin Michael Beranek, Christopher Keakini Kaulia, Vijay Ravindra Kulkarni, Samuel Leonard Moniz, Kyle Bradley Peterson, Ajit Ashok Varangaonkar, Jun Xu

Patent number: 11381639Abstract: Request routing in a network of computing devices. Back-end nodes associated with a request router send load reports to request routers. To select a back-end node for processing a request, a request router determines, based on the reports, estimated loads and corresponding errors of the estimated loads for respective nodes. A load balancing technique may be selected, based on the estimated loads and corresponding errors (e.g., round robin may be selected if the significance of an average error outweighs the difference between estimated load values for the nodes, or least estimated load may be selected of the difference between load values is greater than the average error). The selected technique is applied to choose one of the nodes to process the request. Load probability distribution may also be used for request routing, in combination with or separate from the selection based on the estimated loads.Type: GrantFiled: June 3, 2020Date of Patent: July 5, 2022Assignee: Amazon Technologies, Inc.Inventors: Terence Smith, Paul Derek DeMarco, Michael Shane Thyssen, Christopher Keakini Kaulia, Chaitanya Avinash Kulkarni

Patent number: 11245628Abstract: Request routing in a network of computing devices. Back-end nodes associated with a request router send load reports to the request router that makes routing determinations for request from clients based on the reports. To select a back-end node for processing a request, a request router determines, based on the reports and one or more factors, load probability distributions for each of a group of back-end nodes selected from available back-end nodes. A load value is then randomly selected for each back-end node in the group, based on the node's probability distribution. The node in the group with the least randomly-selected value is chosen to process the request.Type: GrantFiled: June 3, 2020Date of Patent: February 8, 2022Assignee: Amazon Technologies, Inc.Inventors: Terence Smith, Paul Derek DeMarco, Michael Shane Thyssen, Christopher Keakini Kaulia, Chaitanya Avinash Kulkarni

Patent number: 9836388Abstract: The techniques described herein provide software testing of a candidate software system. In some examples, an interceptor intercepts at least one production request to a production software system. The duplicating proxy service causes the at least one intercepted request to be processed by the candidate software system being validated and the production software system being used to validate the candidate software system. The duplicating proxy service may then compare and/or analyze at least one candidate response to the intercepted request from the candidate software system and at least one production response to the intercepted request from the production software system.Type: GrantFiled: September 26, 2013Date of Patent: December 5, 2017Assignee: Amazon Technologies, Inc.Inventors: Samuel Leonard Moniz, Kevin Michael Beranek, Keian Christopher, Andrew Ross Evenson, Christopher Keakini Kaulia, Kyle Bradley Peterson
