Described embodiments provide systems, methods, and computer readable media for generating environment descriptors. A device having at least one process may identify a plurality of feature vectors. Each vector may describe a corresponding access to an application hosted on a server in one of a plurality of network environments and having a corresponding performance metric. The device may provide a performance model using the plurality of feature vectors and the corresponding performance metrics. The performance model may be used to determine expected performance metrics for at least a first network environment. A first environment descriptor of the expected performance metrics may be generated for at least the first network environment. The first environment descriptor of the expected performance metrics may be used to assess a measured performance metric or a second environment descriptor of a second network environment.

Method for computing environment specific baselines for metrics of user experience

Described embodiments provide systems and methods for zone selection for distributed services. A device records latency data measured for interactions between each of a plurality of clients and a service hosted by servers in two or more zones. The device directs network communications from each of the plurality of clients to respective servers hosting the service based on zones assigned to each of the plurality of clients. The device assigns clients to zones based on the recorded latency data. For example, the device identifies a grouping for a client, determines whether the recorded latency data indicates that latency for clients in the grouping is increasing faster than a threshold rate, and selects, responsive to the determination, a zone indicated by a selected set of recorded latency data as lowest in latency.

Heuristics for selecting nearest zone based on ICA RTT and network latency

Systems, methods and computer program products for performing software regression testing are provided. A sitemap comprising a hierarchy of nodes is displayed on a display, each node representing a block of source code for a program. An indication of a user selection of a plurality of nodes in the hierarchy is received. Responsive to receiving the indication, a lowest node of the nodes that is located at a lowest level of the hierarchy is determined and identified as a user selected node. A list of test cases to test the source code represented by the user selected node is displayed. Responsive to receiving an indication of a selection of one of the test cases in the list of test cases displayed, a message having an indication to execute the one of the test cases in the list of test cases displayed is transmitted, to a server device via a network.

Automated selection of test cases for regression testing

Embodiments provide backup up databases using a checkpoint mechanism without requiring saving of transaction logs by: taking a backup snapshot of the database; exposing an iSCSI disk using the snapshot backup as a target by encapsulating the snapshot in a virtual disk; creating a read/write differencing disk for the exposed iSCSI disk; replaying transaction logs onto the iSCSI disk; and streaming the contents of the virtual disk to a storage medium to create a saveset.

Logless backup of databases using internet SCSI protocol

Embodiments provide granular recovery of virtual machine backups by generating the virtual machine backups comprising virtual disks that are configured as iSCSI targets; exposing, with an iSCSI server, the virtual disks as a logical unit number to an iSCSI client; performing SCSI read operations from the virtual disk using defined application program interfaces (APIs); and mounting a backup save set comprising the virtual disk files as a local disk on a computer where data recover is to be performed. Embodiments also emulate virtual disk storage as an iSCSI target by exposing the virtual disk as a logical unit number to an iSCSI client and mounting a backup save set as a local disk in an iSCSI server executing a backup process defining a granularity for data restore operations.

Cross-platform instant granular recovery for virtual machine backups

Information identifying a set of changed blocks on a volume of a client are received. The changed blocks are blocks of the volume that have changed since a previous backup of the client. The set of changed blocks are filtered to identify a subset of changed blocks that are associated with a particular file. The subset of changed blocks is streamed to a backup storage server for storage as an incremental virtual hard disk file. The incremental virtual hard disk file is associated to a full backup virtual hard disk file, where the full backup virtual hard disk file is a full backup of a previous version of the particular file.
