Publication number: 20190281110Abstract: Techniques for migrating virtual desktop sessions in a sticky session environment are disclosed. A load balancer can select a first server to service requests sent by a client, and select a second server to store session data associated with the requests. The load balancer can cause the first server to initiate a transmission of the session data to the second server. The load balancer can forward the requests to the second server in response to determining that a load-related event has occurred. A method, system, and computer-readable medium are provided.Type: ApplicationFiled: May 29, 2019Publication date: September 12, 2019Inventors: Prashant KUMAR, Vineet Kumar SINHA, Prasenjit SARKAR, Anoop SHUKLA, Hrishikesh DALVI

Patent number: 10348812Abstract: Techniques for managing session data in a computer system having a plurality of servers establishing sessions with clients. Communications from any particular client are forwarded to the server assigned to handle that client. A load balancer may determine that any particular session for any particular client should be moved between servers, based on load balancing criteria. In this case, the load balancer causes session data for the server assigned to the client to be transferred to a different server. Acknowledgment signals are sent between the servers and load balancer to indicate completion status. Load balancer maintains backup data at secondary servers which can be brought online when a primary server becomes unresponsive. A method, system, and computer-readable medium are provided.Type: GrantFiled: October 16, 2015Date of Patent: July 9, 2019Assignee: VMware Inc.Inventors: Prashant Kumar, Vineet Kumar Sinha, Prasenjit Sarkar, Anoop Shukla, Hrishikesh Dalvi

Patent number: 10241897Abstract: Systems and techniques are described for identifying test gaps. A described technique includes identifying production code paths for an application. Each production code path specifies a respective sequence of code of the application that was executed in a production environment. Test code paths are identified for the application. Each test code path specifies a respective sequence of the application that was tested in a test environment.

Patent number: 9672029Abstract: Test case priorities are automatically determined based on the execution path of a software application that includes priority tags. By embedding the priority tags in the source code of the software application, the consistency and reliability of the test case priorities is improved compared to conventional, primarily manual approaches to determining test case priorities. Further, efficiency is increased by providing run-time feedback regarding test cases that facilitates identification of the highest priority test cases and corresponding test suite optimizations.Type: GrantFiled: September 16, 2014Date of Patent: June 6, 2017Assignee: VMware, Inc.Inventors: Vineet Kumar Sinha, Prasenjit Sarkar, Rishi Kant Sharda

Patent number: 9612935Abstract: A computer implemented method for testing the resiliency of a software application. The computer implemented method can test the resiliency of a software application by monitoring the program state of the software application and trigger a shutdown request when the specified program state has been reached. The shutdown request can be transmitted to the application software and executed to shut down one or more functionalities of the software application. In some examples, the method can specify the functionality to shut down and the program state which the shutdown occurs can be specified in an application configuration file.Type: GrantFiled: February 2, 2015Date of Patent: April 4, 2017Assignee: VMware, Inc.Inventors: Vineet Kumar Sinha, Prasenjit Sarkar, Sree Ranga Sudha T K, Prashant Kumar, Anoop Shukla

Patent number: 9313263Abstract: Techniques for assigning applications to datastores in a virtual machine environment are disclosed. In an embodiment, applications exhibiting different I/O data access patterns are assigned to datastores by collecting data related to the input-output operations performed by the applications, analyzing the collected data to identify corresponding data access patterns, and assigning applications to datastores based on the identified data access patterns. In this way, applications can be segregated by data access pattern onto separate datastores. For example, random I/O apps and sequential I/O apps can be assigned to different datastores. Additionally, if random I/O apps are found to be comingled with sequential I/O apps on the same datastore, then data associated with the applications can be migrated as necessary to achieve segregation. In an embodiment, random I/O apps and sequential I/O apps are segregated onto datastores that rotate independent of each other.Type: GrantFiled: January 29, 2014Date of Patent: April 12, 2016Assignee: VMware, Inc.Inventors: Prasenjit Sarkar, Vineet Kumar Sinha
