A method for managing a plurality of computing machines includes accessing a catalogue memory structure storing a plurality of component signatures, discovering one or more of the software components being instantiated in a software image of each computing machine according to corresponding ones of the component signatures, detecting one or more connections each being established between at least two instantiated software components of different computing machines, receiving a restore command for restoring a target recovery point selected among a plurality of recovery points, and restoring the target recovery point in response to the restore command by restoring the snapshots associated with the target recovery point on corresponding computing machines.

Method and system to discover and manage distributed applications in virtualization environments

A solution is proposed for managing each one of a plurality of computing machines. A corresponding method comprises taking one or more snapshots of the computing machine or part thereof, the snapshots being organized in a snapshot tree of nodes representing the snapshots according to a dependency thereof, expanding the snapshot tree of the computing machine according to each sub-tree of the snapshot tree of each other computing machine having the snapshot of a parent node of the sub-tree matching a graft node of the snapshot tree of the computing machine, the sub-tree being appended to the graft node, selecting a snapshot of the other computing machines represented by a selected node of the snapshot tree of the computing machine, and restoring the selected snapshot on the computing machine.

Sharing of snapshots among multiple computing machines

A method for managing computing machines. The method includes accessing a catalog storing component signatures for discovering corresponding software components and, for each software application, an indication of the software components belonging to the software application and connection signatures for detecting corresponding connections between the software components, discovering the software components instantiated in a software image according to the corresponding component signatures, detecting the connections each one being established between instantiated software components of different computing machines according to the corresponding connection signatures, associating each software image with a software deployment of the software application of each established connection of the software image, receiving a restore command for restoring a target recovery point selected among recovery points, each recovery point comprising a previously taken snapshot of each software image of the software deployments being overlapped, and restoring the target recovery point by restoring the snapshots on the corresponding computing machines.

A method, an eBook, and an apparatus. The method includes calculating, by a processor, a usage metric describing a timing at which an eBook has been displayed for viewing by a user. The method further includes selectively deteriorating, by the processor, a look of the eBook for a secondary market based on the usage metric of the eBook.

Selectively deteriorate eBook for secondary market

A computer implemented method for deploying, in a distributed virtual environment, a multi-component software product is disclosed. The method may include requesting and receiving product installation parameters, which may include virtual machine IDs corresponding to subsets of the product installation parameters. The method may also include copying software product installation files and parameters onto a first virtual machine, halting the first virtual machine, cloning the first virtual machine to a second virtual machine and setting virtual machine IDs on the virtual machines. The method may also include starting the virtual machines and identifying, based on virtual machine IDs, subsets of the product installation parameters. The method may also include deploying, based on subsets of the product installation parameters, the software product by installing first and second components of the software product on the first and second virtual machines, respectively.
