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.

System and method for event-driven live migration of multi-process applications

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.

System and method for hybrid kernel and user-space checkpointing using a character device

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.

Method and system for providing coordinated checkpointing to a group of independent computer applications

A system, method, and computer readable medium for hybrid kernel-mode and user-mode checkpointing of multi-process applications. 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.

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.

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.

System and method for hybrid kernel- and user-space incremental and full checkpointing

Providing streaming of one or more applications from streaming servers onto one or more clients. The computer readable medium includes computer-executable instructions for execution by a processing system. The applications are contained within one or more isolated environments, and the isolated environments are streamed from the servers onto clients. 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 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.

System and method for streaming application isolation

A system includes a multi-process application that runs. A multi-process application runs on primary hosts and is checkpointed by a checkpointer comprised of at least one 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.

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.

A system and method for storage checkpointing to a group of independent computer applications. The system has a storage disk that stores files; a storage access interface to access the storage disk; and a computer. The computer runs the group of independent computer applications and utilizes the files stored on the storage disk. A file system on the server accesses the files stored on the storage disk. An operating system and at least one device driver can be called by the file system, and at least one buffer buffers first data written to the storage disk and second data read from the storage disk.

Method and system for providing storage checkpointing to a group of independent computer applications

An operation comprising one or more of loading one or more primary applications and including said one or more primary applications in a synchronization point, halting execution of said one or more primary applications upon arriving at said synchronization point, triggering a migration of said one or more primary applications to one or more backup applications, wherein said migration starts when the execution of said one or more primary applications are halted at said synchronization point.
