    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: Embodiments of the present invention include systems and methods for controlling input-output (IO) requests of a plurality of virtual machines to a datastore. The method includes: monitoring, for each virtual machine, a throughput of IO to a datastore for a preset time interval; identifying a peak value of the throughput; calculating a value of input-output-per-second (IOPS) using the peak value; and setting the value of IOPS as an IOPS limit for a corresponding virtual machine.

    Abstract: 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 code of the application that was tested in a test environment. The production code paths are compared to the test code paths to identify a set of first test gaps for the application. Each first test gap specifies a respective production code path that is not included in the test code paths. Test gap data specifying the first test gaps for the application can be provided for presentation to a user.
