Patent number: 10656868Abstract: Technologies for cluster systems that are natively geo-site-aware. Such a cluster system makes use of this awareness to determine the subsets of nodes located at various geo-sites at physical configuration, to optimize workload placement based on the geo-sites, to make failover and failback decisions based on the geo-sites, and to assign voting and prune nodes for quorum management based on the geo-sites. Such capabilities result in cluster systems that are more resilient and more efficient in terms of resource usage than cluster systems without such native geo-site awareness.Type: GrantFiled: March 8, 2018Date of Patent: May 19, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Lokesh Srinivas Koppolu, David Allen Dion, Abhinit Kumar, Suresh Chandra Pippari, Amitabh Tamhane, Elden Christensen

Patent number: 9268672Abstract: Some implementations include receiving an application binary file for an application to be tested. One or more static analysis operations may be performed on the application binary file to identify application parameters. In some cases, keywords may be associated with individual application parameters, and the keywords may be used to query a test case repository in order to identify test cases. The identified test cases may be used to generate a test plan, and at least a portion of the test plan may be automatically executed in some cases. A test report may be generated that includes a list of test case failures and potential solutions, and the test report may be sent e.g., to a third-party developer or an approval engineer for review.Type: GrantFiled: May 27, 2014Date of Patent: February 23, 2016Assignee: Amazon Technologies, Inc.Inventor: Suresh Chandra Gupta
