Patent number: 11210270Abstract: A system that maps files into multiple parts and initiates storage of each part within a respective storage provider. The mapping facilitates this by correlating each of the multiple parts to a corresponding storage provider which may be different than the storage provider that stores a different part of the same file. The system then initiates storage of the multiple parts of the file in each of their corresponding storage provider in accordance with the mapping, and using a storage-provider-facing API. Similarly, retrieval and/or editing of a partial file may be accomplished by referencing the mapping, and using the same API issued to the appropriate storage provider. Each storage provider is capable of interfacing with the system using this same API.Type: GrantFiled: September 15, 2017Date of Patent: December 28, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Peng Li, Raghunath Ramakrishnan, Baskar Sridharan, Christopher William Douglas, Virajith Jalaparti, Sriram Rao, Sri Sai Kameswara Pavan Kumar Kasturi, Karthick Krishnamoorthy, Chakrapani Bhat Talapady, Krishna Pradeep Reddy Tamma

Patent number: 10936367Abstract: Described herein is a system and method for ranking and/or taking an action regarding execution of jobs of a shared computing cluster based upon predicted user impact. Information regarding previous executions of a plurality of jobs is obtained, for example, from job execution log(s). Data dependencies of the plurality of jobs are determined. Job impact of each of the plurality of jobs as a function of the determined data dependencies is calculated. User impact of each of the plurality of jobs as a function of the determined data dependencies, the calculated job impact, and time is calculated. The plurality of jobs are ranked in accordance with the calculated user impact. An action is taken in accordance with the ranking of the plurality of jobs. The action can include automatic scheduling of the jobs and/or providing information regarding the rankings to a user.Type: GrantFiled: January 22, 2019Date of Patent: March 2, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Carlo Aldo Curino, Konstantinos Karanasos, Subramaniam Venkatraman Krishnan, Christopher William Douglas, Sriram S Rao, Andrew F Chung

Patent number: 9876878Abstract: Embodiments are directed to progressively migrating source computer nodes where the source computer nodes perform a computer-implemented service. In one embodiment, a computer system determines that execution of the performed service is to be migrated from the source computer nodes to target computer nodes. The computer system groups the source computer nodes into multiple source subgroups, where each source subgroup includes at least one source computer node. The computer system then schedules creation of target subgroups of target nodes. These target subgroups include at least one source computer node and, themselves, correspond to a source subgroup. The computer system activates a first target subgroup corresponding to a first source subgroup, and deactivates the first source subgroup. In this manner, the first target subgroup replaces the first source subgroup. Still further, the target subgroups are scheduled to be created only after the first source subgroup has been deactivated.Type: GrantFiled: January 20, 2017Date of Patent: January 23, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Kishore Chaliparambil, Carlo Curino, Kannababu Karanam, Subramaniam Venkatraman Krishnan, Christopher William Douglas, Sriram Rao, Mostafa Elhemali, Chuan Liu
