Abstract

Methods may provide peak load processing on a computer system. A method may include receiving at a remote computer system a request from a local computer system, coupled to the remote computer system by a network, to replicate at the remote computer system a local instance of an application executing on the local computer system that is subject to user requests received at the local computer system. The method may further include replicating on the remote computer system a remote instance of the application and redirecting user requests from the local computer system to the remote computer system. The method may further include executing on the remote computer system the remote instance of the application, including processing with the remote instance of the application user requests redirected from the local computer system to the remote instance of the application.

Claims

1. A method comprising:

receiving at a remote computer system a request from a local computer system, coupled to the remote computer system by a network, to replicate at the remote computer system a local instance of an application executing on the local computer system that is subject to user requests received at the local computer system;

replicating on the remote computer system a remote instance of the application;

redirecting user requests from the local computer system to the remote computer system; and

executing on the remote computer system the remote instance of the application, including processing with the remote instance of the application user requests redirected from the local computer system to the remote instance of the application.

2. The method according to claim 1, further comprising monitoring the execution of the remote instance of the application, and in response to reaching an operation threshold, sending to the local computer system an indication related to the reaching of the operation threshold.

3. The method according to claim 1, further comprising providing the local computer system with data associated with the remote instance of the application.

4. The method according to claim 1, further comprising sending to the local system responses produced by the application to the received user requests for redirection to the users that submitted the corresponding user requests.

5. The method according to claim 1, wherein replicating on the remote computer system a remote instance of the application running on the local system includes initiating termination of the execution of the local instance of the application, and receiving a copy of the application and configuration of the local instance of the application after the local instance of the application has terminated.

6. The method according to claim 1, where the local computer system is coupled to the Internet, associated with a domain having a DNS entry providing access by users, and wherein redirecting user requests from the local computer system to the remote computer system includes dynamically assigning the domain to a DNS entry of the remote computer system.

7. The method according to claim 1, wherein replicating on the remote computer system a remote instance of the application includes replicating a data base of the local computer system on the remote computer system.

8. A method comprising:

executing at a local computer system a local instance of an application;

receiving at the local computer system user requests for use of the application;

processing with the local instance of the application a first portion of the received user requests; and

sending to a remote computer system, operatively coupled to the local computer system by a network, a second portion of the received user requests.

9. The method according to claim 8, further comprising monitoring the processing of the received user requests at the local computer system, and wherein the second portion of the received user requests are sent to the remote computer system in response to the reaching of an operation threshold.

10. The method according to claim 8, further comprising, prior to sending the second portion of the received user requests, terminating the executing of the local instance of the application at the local computer system, and wherein sending to the remote computer system the second portion of the received user requests includes sending all of the user requests to the remote computer system while the local instance of the application is terminated.

11. The method according to claim 8, further comprising receiving at the local computer system data associated with the remote instance of the application.

12. The method according to claim 8, further comprising receiving from the remote computer system responses to user requests sent to the remote computer system, and sending the received responses to the users that submitted the corresponding user requests.

13. The method according to claim 8, further comprising sending a copy of the application and configuration of the local instance of the application to the remote computer system, and prior to sending to the remote computer system the second portion of the received user requests, receiving an indication from the remote computer system that a remote instance of the application has been provisioned at the remote computer system.

14. The method according to claim 8, further comprising providing access by the remote computer system to a data base of the local computer system.
