A server receives from a client device that is executing a client application a request to initiate a remote application in the server. The server instantiates an instance of the remote application. The server intercepts draw commands associated with the remote application instance. The server provides the draw commands to the client to cause the client application to render portion(s) of output based on the draw commands. The server receives an input event from the client application. The server provides the client one or more draw commands based on the input event to cause the client application to render portion(s) of output based on those draw commands.

Application remoting across a network using draw commands

A remote browsing session is initiated between a remote browser client executing on a client device and a remote browser host executing on a remote browser server. The remote browser host receives from the client device, encrypted remote browser data of remote browser data that affects the remote browser session. The remote browser client does not have access to a decryption key for the encrypted remote browser data. The encrypted remote browser data is decrypted to reveal the remote browser data. The remote browser host is configured with the remote browser data. The remote browser host manages updates to the remote browser data during the remote browsing session. Periodically, updates to the remote browser data are encrypted and transmitted to the remote browser client for storage.

Persisting encrypted remote browser data at a local browser for use in a remote browser

A client device instantiates an isolator application. A request to instantiate a remote application in a server device is sent by the isolator application instance. The isolator application instance receives, from the remote application instance, draw commands and position information that correspond to the draw commands. The isolator application instance renders one or more portions of output based on the draw commands and the position information.

Remoting application across a network using draw commands with an isolator application

A server receives from a client device that is executing a web browser application a request to initiate a remote application in the server. The server instantiates an instance of the remote application. The server intercepts draw commands associated with the remote application instance. The server provides the draw commands to the client to cause the web browser application to render portion(s) of output based on the draw commands. The server receives an input event from the web browser application. The server provides the client one or more draw commands based on the input event to cause the web browser application to render portion(s) of output based on those draw commands.

Web browser remoting across a network using draw commands

A remote browsing session is initiated between a remote browser client executing on a client device and a remote browser host executing on a remote browser server. The remote browser host receives from the client device, encrypted remote browser data of remote browser data that affects the remote browser session. The remote browser client does not have access to a decryption key for the encrypted remote browser data. The encrypted remote browser data is decrypted to reveal the remote browser data including data for one or more cookies. The remote browser host is configured with the remote browser data. The remote browser host manages updates to the remote browser data during the remote browsing session including updates to one or more cookies. Periodically, updates to the remote browser data are encrypted and transmitted to the remote browser client for storage.

Methods, systems, and techniques for application isolation by remote-enabling applications are provided. Example embodiments provide an Adaptive Rendering Application Isolation System ('ARAIS'), which transparently and dynamically enables applications to run in an isolated execution environment yet be rendered locally in a manner that minimizes the amount of data to be transferred and the latency caused by expensive computation and/or by overburdening available bandwidth by remoting rendering using draw commands over rendering using pixel pushing or other techniques. In one embodiment, the ARAIS includes an orchestrator server which comprises remoting level determination logic and rules engine, pre-computed graphics libraries, connection support logic, data repositories for objects such as a render cache, whitelists, blacklists, client privileges, and application information, and one or more secure containers running remote application instances. These components cooperate to deliver isolation-ready technology to client applications.

Application remoting using network vector rendering

Methods, systems, and techniques for application isolation by remote-enabling applications are provided. Example embodiments provide an Adaptive Rendering Application Isolation System ('ARAIS'), which transparently and dynamically enables applications to run in an isolated execution environment yet be rendered locally via a local isolator application having one or more cohesive application-isolation interfaces in a manner that facilitates providing the ARAIS indications of user actions that are otherwise lost and executing functions that are otherwise unavailable during fully secure isolation sessions absent one or more cohesive application-isolation interfaces. In one embodiment, the ARAIS includes an orchestrator server which comprises remoting level determination logic and rules engine, pre-computed graphics libraries, connection support logic, data repositories for objects such as a render cache, whitelists, blacklists, client privileges, and application information, and one or more secure containers running remote application instances. These components cooperate with the one or more cohesive application-isolation interfaces of the isolation application to provide isolation sessions with a user experience that is typically available only during non-isolation sessions.
