Abstract:
A system, method, and computer readable medium for asynchronous live migration of applications between two or more servers. The computer readable medium includes computer-executable instructions for execution by a processing system. Primary applications runs on primary hosts and one or more replicated instances of each primary application run on one or more backup hosts. Asynchronous live migration is provided through a combination of process replication, logging, barrier synchronization, checkpointing, reliable messaging and message playback. The live migration is transparent to the application and requires no modification to the application, operating system, networking stack or libraries.
Abstract:
A method and system of checkpointing single process application groups and multi-process application groups. In an exemplary embodiment, the method may include creating at least one full checkpoint for each application in an application group, and creating at least one incremental application checkpoint for each application in the application group. Further, each of the at least one incremental application checkpoint may be automatically merged against a corresponding full application checkpoint. Further, checkpointing may be synchronized across all applications in the application group. In the exemplary embodiment, each application may use both fork( ) and exec( ) in any combination.
Abstract:
A computer readable medium and method providing checkpointing to Windows application groups, the computer readable medium having computer-executable instructions for execution by a processing system. The computer-executable instructions may be for launching an application and creating one or more application threads, receiving a checkpoint signal by an application thread, and entering a checkpoint Asynchronous Procedure Call (APC) handler at IRQL APC_LEVEL, the APC handler disposed in a kernel module, acquiring an ETHREAD block and user-mode context for the application thread, and examining an execution state of the one or more application threads at a time of the checkpoint signal.
Abstract:
A system, method, and computer readable medium for usage billing of one or more hosted applications serving one or more clients. The hosted applications are contained within one or more isolated environments or run without isolated environments. The system may include usage billing based on one or more of resources open, amount of data flowing through resources, number of open files, number of transactions, number of concurrent users, number of processes, CPU utilization and memory usage, The system may further include a management interface where administrators may add, remove and configure isolated environments, configure client policies and credentials, and force upgrades. If using isolated environments, the isolated environments may be isolated from other applications and the host operating system on the clients and applications within the isolated environments may run without performing an application-installation on the client.
Abstract:
A system, method, computer program, and/or computer readable medium for providing application isolation and live migration to one or more applications and their associated resources. The computer readable medium includes computer-executable instructions for execution by a processing system. The computer-executable instructions may be for creating a new isolated environment, for creating a copy of an isolated environment, live migrating applications within and between isolated environments, and for deploying an isolated environment Further, the instructions may be for launching one or more applications within one or more isolated environment, for terminating one or more applications within one or more isolated environments, for configuring resource mappings, exceptions and policies, for triggering a live migrate, and for delivery of one or more applications within isolated environments over the network.

Abstract:
A system and method thereof for performing loss-less migration of an application group. In an exemplary embodiment, the system may include a high-availability services module structured for execution in conjunction with an operating system, and one or more computer nodes of a distributed system upon which at least one independent application can be executed upon. The high-availability services module may be structured to be executable on the one or more computer nodes for loss-less migration of the one or more independent applications, and is operable to perform checkpointing of all state in a transport connection.

Abstract:
Providing streaming of applications from streaming servers onto clients. The applications are contained within isolated environments, and the isolated environments are streamed from the servers onto clients. The system may include the option of running both in on-line and off-line. When on-line, the system may include authentication of the streaming servers and authentication of clients and credentialing of the isolated environments and applications the clients are configured to run. The system may further include encrypted communication between the streaming servers and the clients. When off-line, the system may include the ability to run already installed isolated environments without requiring credentialing. The system may further include a management interface where administrators may add, remove and configure isolated environments, configure client policies and credentials, and force upgrades.
