Session transfer and suspension in a remote access application framework
Systems and method for providing for suspension and transfer of remote access sessions. In accordance with the methods, a request to suspend a session may be received at a server tier. The server tier prepares a URL that may be used at a later time by a client to resume the session. The URL is communicated to a client tier from which the request was received and, thereafter, a connection between the client tier and the server tier is closed. At a subsequent time, a request may be received to resume the session at the URL. After receipt of the request to resume the session, a connection with the requesting client tier is established by the server tier, and the session is resumed.
1. A method for migrating a virtual machine from a first server to a second server, the virtual machine being accessible by a client computing device over a network, the method comprising:
suspending the virtual machine at the first server;
saving application state information associated with an application executing on the virtual machine when suspending the virtual machine;
moving the virtual machine from the first server to the second server;
updating a mapping of a Uniform Resource Locator (URL) used to resume the virtual machine to an address associated with the second server; and
subsequent to the updating, receiving a request from the client computing device at the URL to resume the virtual machine.
2. The method of claim 1 , wherein the URL includes a data structure representing a session between the client computing device and the virtual machine.
3. The method of claim 2 , further comprising using the URL to associate the client computing device to the virtual machine.
4. The method of claim 1 , further comprising saving application-related information associated with the virtual machine when moving the virtual machine to the second server.
5. The method of claim 1 , further comprising resuming the application using the application state information.
6. The method of claim 1 , further comprising authenticating the request at the URL using a password provided by the client computing device.
7. A method to migrate a virtual machine, comprising:
suspending a virtual machine at a first server, the virtual machine executing an application that is remotely accessed by a client device over a network;
moving the virtual machine from the first server to a second server, the second server being accessible by the client device over the network;
updating a mapping associated with a Uniform Resource Locator (URL) used to resume the virtual machine to an address associated with the second server; and
subsequent to the updating, receiving a request from the client computing device at the URL to resume the virtual machine and to resume the application using saved application-related information associated with the application.
8. The method of claim 7 , wherein the URL is a data structure representing a session between the client computing device and the application executing on the virtual machine.
9. The method of claim 8 , further comprising using the URL to associate the client computing device to the application executing on the virtual machine.
10. The method of claim 9 , further comprising resuming the application using application state information.
11. The method of claim 7 , further comprising authenticating the request at the URL using a password provided by the client computing device.
12. A tangible computer readable media containing computer-executable instructions that when executed by a computing device perform migration of a virtual machine from a first server to a second server, the virtual machine being accessible by a client computing device over a network, the instructions performing a method comprising:
suspending the virtual machine at the first server;
saving application state information associated with an application executing on the virtual machine when suspending the virtual machine;
moving the virtual machine from the first server to the second server;
updating a mapping of a Uniform Resource Locator (URL) used to resume the virtual machine to an address associated with the second server; and
subsequent to the updating, receiving a request from the client computing device at the URL to resume the virtual machine.
13. The computer readable media of claim 12 , wherein the URL includes a data structure representing a session between the client computing device and the virtual machine.
14. The computer readable media of claim 13 , further comprising instructions for using the URL to associate the client computing device to the virtual machine.
15. The computer readable media of claim 12 , further comprising instructions for resuming the application using the application state information.
16. The computer readable media of claim 12 , further comprising instructions for authenticating the request at the URL using a password provided by the client computing device.
