A method for recording and replaying execution of an application running on a computer system using a program module is provided. The method includes recording events which result from the execution of the application including a non-deterministic event, wherein the program module deterministically records the non-deterministic event, saving the recorded events for deterministic replay of the recorded execution, restoring the saved recorded events, and deterministically replaying the recorded execution of the application.

Methods, systems; and media for application fault containment are provided. In accordance with some embodiments, a method for application fault containment is provided, the method comprising: determining a plurality of applications associated with a processing device; isolating each of the plurality of applications into an application container; receiving a user selection of one of the plurality of applications; and creating the application container of a container type for the user selected application in response to receiving the user selection; wherein, upon determining that the container type is a persistent container, configuring the created application container to maintain state information across executions of the user selected application, and wherein, upon determining that the container type is an ephemeral container, configuring the created application container to be removed after a single execution of the user selected application.

A method and system are provided for executing an application remotely on a server computer for a client computer in a computer network. The server receives at user input from the client computer associated with the application, and executes the application. The server processes display commands of the application to generate display primitives, and translates the display primitives into lower level display commands defining display updates using semantic information of the display primitives. The lower level display commands are selected from a predetermined set of lower level display commands. The lower level display commands are aggregated and ordered into one or more command queues. Each command queue is associated with a given display region. The server computer transmits the lower level display commands in the one or more command queues over the network to the client computer. The client computer is capable of translating the lower level display commands into hardware calls for causing the client computer to display the display updates.
