Abstract:
A system, method, and computer readable medium for providing optimized streaming of one or more applications from streaming servers onto one or more clients. The one or more applications are contained within one or move isolated environments, and the isolated environments are streamed from the servers onto clients. The streaming is optimized using update-caches which are maintained on the streaming server and compared against the client's most recent update-caches. The update-caches are updated when applications are installed, removed or patched inside particular isolated environment and when the operating system is patched or updated. 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. 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. The streamed 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, 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 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.
Abstract:
A system, method, and computer readable medium for providing application isolation to one or more applications and their associated resources. The system may include one or more isolated environments including application files and executables, and one or more interception layers intercepting access to system resources and interfaces. Further, the system may include an interception database maintaining mapping between the system resources inside the one or more isolated environments and outside, and a host operating system. The one or more applications may be isolated from other applications and the host operating system while running within the one or more isolated environments.
Abstract:
A system includes a multi-process application that runs on primary hosts and is checkpointed by a checkpointer comprised of a kernel-mode checkpointer module and one or more user-space interceptors providing at least one of barrier synchronization, checkpointing thread, resource flushing, and an application virtualization space. Checkpoints may be written to storage and the application restored from said stored checkpoint at a later time. Checkpointing may be incremental using Page Table Entry (PTE) pages and Virtual Memory Areas (VMA) information. Checkpointing is transparent to the application and requires no modification to the application, operating system, networking stack or libraries. In an alternate embodiment the kernel-mode checkpointer is built into the kernel.
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, method, and computer readable medium for hybrid kernel-mode and user-mode checkpointing of multi-process applications using a character device. The computer readable medium includes computer-executable instructions for execution by a processing system. A multi-process application runs on primary hosts and is checkpointed by a checkpointer comprised of a kernel-mode checkpointer module and one or more user-space interceptors providing barrier synchronization, checkpointing thread, resource flushing, and an application virtualization space. Checkpoints may be written to storage and the application restored from said stored checkpoint at a later time. Checkpointing is transparent to the application and requires no modification to the application, operating system, networking stack or libraries. In an alternate embodiment the kernel-mode checkpointer is built into the kernel.
Abstract:
A method and system for checkpointing at least one application in an application group. At least one full checkpoint and at least one incremental checkpoint are created for the application in the application group. The at least one incremental application checkpoint is merged against the at least one full application checkpoint, and checkpointing across all applications in the application group is synchronized. A storage checkpoint is taken for at least one of the full checkpoint and the incremental checkpoint, and memory and storage checkpoints are synchronized and consistent.
