A mechanism is provided for deploying software applications in a cloud computing environment. An administrator is provided an interface for allowing a software application that is designed for a single tenant to be used by a plurality of users. An aspect of the invention is to provide a mechanism for quickly and easily giving multi-user qualities to a single tenant application like autoCAD. As such, multiple users can access the application without the need to download and install a version locally on their system. The system is able to determine the period of time for which an application is in use for a given user, because every application is run on a resource that is part of the cloud environment. Therefore, it is possible for the application provider to charge for the application in a usage-based model—e.g., by the hour, or day—without any re-engineering of the existing application.

A method for selecting a communication protocol for a virtual desktop instance in a service provider environment may include providing to a client computing device, access to a virtual desktop instance running on a server computer using a first communication channel associated with a first communication protocol. A request for functionality from a user of the device is detected, the requested functionality being unsupported by the first communication protocol. A second communication protocol from a plurality of available communication protocols may be selecting based on the requested functionality. The second communication protocol may support the requested functionality. A user authorization for using the second communication protocol can be verified. Upon successful verification, a second communication channel is established between the server computer and the device using the second communication protocol for performing the functionality, while maintaining access to the virtual desktop instance using the first communication channel.

Using multiple protocols in a virtual desktop infrastructure

Systems and methods are described for a connection service that identifies connections for providing a data flow between a client computing device and a target computing device. A client computing device can send an API-based connection request to various servers hosting the connection service. The connection service processes the requests to determine a routing path for the connection. Advantageously, the connection service determines various routing paths and further identifies a connection for the data stream using that routing path. Finally, a control service provides control and relays requests to initiate data flows for resources configured for a data flow (e.g., a remote desktop session).

Connection service with network routing

Systems and methods are described for a connection service that identifies routing paths for providing a data flow between a client computing device and a target computing device. A client computing device can send an API-based connection request to various servers hosting the connection service. The connection service processes the requests to determine a routing path for the connection. Advantageously, the connection service selects a routing path from a plurality of available routing paths if a client computing device is associated with a network address translator. The connection service may provide an externally addressable network address if it determines that no such address is available for routing of a data flow.

Systems, methods, and computer-readable storage media are disclosed for roaming profiles and application compatibility in multi-user systems. In an embodiment, a user profile exists on a plurality of client computers. Each client computer executes a roaming profile client that intercepts a change to an application's settings. The roaming profile client sends this change to a roaming profile server that stores it. When the user profile logs on to a second client computer, the roaming profile server sends an indication of the change to a second roaming profile client on the second client computer. This roaming profile client alters the settings for the application on the second client computer such that, when the user session executes the application on the second client computer, the application reflects the change.

Roaming profiles and application compatibility in multi-user systems

A mechanism is provided for presenting a software application to a plurality of users in a cloud computing environment. For example, an application that was designed for use by a single user is provided in a cloud based platform without re-architecting the application. Using a web-based interface, multiple cloud users may launch and execute the application. The various instances of the application are provided to the cloud users as if the application were designed as a multi-user application.

Multi tenant access to applications

An invention is disclosed for conducting a remote presentation session with a client that uses a web browser to conduct the session. In embodiments, a proxy server exists between the remote presentation server and the client. The proxy server establishes a HTTP session with the client and a remote presentation session with the client. The server generates graphics encoded with a remote presentation protocol and sends them to the proxy, which re-encodes them as video and sends them to the client for display in the web browser. The client captures user input at the web browser and sends it to the proxy, which encodes it with the remote presentation protocol and sends it to the server to be processed.

Web-browser based desktop and application remoting solution

In various embodiments, a remote client is allowed to access at least a part of a connection service located on alternate sources other than the primary remote presentation server. In some embodiments, the remote presentation virtual channels may be split into multiple connections with the purpose of allowing better flow control. Some embodiments may be implemented in a virtual machine environment for cases in which the data to be transferred through a data channel is located in the host virtual machine partition but the remote endpoint is located on the guest virtual machine partition.

Multi-link remote protocol

A method includes determining if a server supporting an application and a client having remote desktop access to the server are on a same physical computing device. Upon determining that the server and the client are on the same physical computing device, graphics data related to the application is stored from the server to shared memory that is accessible by the server and by the client. Information to enable the client to retrieve the graphics data stored by the server in the shared memory is communicated from the server to the client.

Selective use of shared memory for remote desktop application

Systems, methods, and computer-readable storage media are disclosed for virtualized eco-friendly remote presentation session roles. In an embodiment, a connection broker monitors the servers of a server farm, and, based upon characteristics of remote presentation sessions served by VMs executing on those servers, directs VMs on those servers to be migrated between servers, changed from sleeping to running or vice versa, or other operations that may improve the performance of the server farm as a whole.

Virtualized management of remote presentation sessions using virtual machines having load above or below thresholds

A method for offloading remote terminal services processing tasks to a peripheral device that would otherwise be performed in a computer system's processor and memory. In one embodiment, the disclosed method is utilized in a layered network model, wherein computing tasks that are typically performed in network applications are instead offloaded to a peripheral such as a network interface card (NIC).

Hardware acceleration for remote desktop protocol

In various embodiments, methods and systems are disclosed for integrating a remote presentation protocol with a datagram based transport. In one embodiment, an integrated protocol is configured to support lossless or reduced loss transport based on Retransmission (ARQ) combined with Forward Error Correction (FEC). The protocol involves encoding and decoding of data packets including feedback headers and FEC packets, continuous measurement of RTT, RTO and packet delay, dynamically evaluating loss probability to determine and adjust the ratio of FEC, congestion management based on dynamically detecting increase in packet delay, and fast data transmission rate ramp-up based on detecting a decrease in packet delay.
