Abstract

Systems and computer program products may provide peak load processing on a computer system. A first computer system may include a processor and a memory storage device operatively coupled to the processor. The memory storage device may store instructions that are executed by the processor to receive from a second computer system coupled to the first computer system by a network, a request to replicate at the first computer system a first instance of an application executing on the second computer system, replicate on the first computer system the first instance of the application and execute the first instance of the application on the first computer system, including processing user requests related to the application received from the second computer system.

execute the instance of the application on the first computer system, including processing user requests related to the application received from the second computer system.

2. The first computer system according to claim 1, wherein the memory storage device further stores instructions that are executed by the processor to provide the second computer system with data associated with execution of the instance of the application on the first computer system.

3. The first computer system according to claim 1, wherein the memory storage device further stores instructions that are executed by the processor to send responses produced by the application on the first computer system to the received user requests to the second computer system for redirection to the users that submitted the corresponding user requests.

4. The first computer system according to claim 1, wherein the memory storage device further stores instructions that are executed by the processor to provide resources of the first computer system for use by a developer in developing the application, and after the application is developed, downloading the application to the second computer system.

5. The first computer system according to claim 1, wherein the memory storage device further stores instructions that are executed by the processor to initiate termination of the execution of the instance of the application on the first computer system, and receive a copy of the application and configuration of the instance of the application on the second computer system after the instance of the application on the first computer system has terminated.

6. The first computer system of claim 1, further comprising receiving new user requests from the second computer system and executing the new user requests on the first computer system, the new user requests received after receiving the application information, wherein the first computer system and the second computer system are connected through a router accessed at an Internet Protocol (“

IP”

) address and each of the first computer system and the second computer system include a subnet address such that the new user requests received on the IP address and intended for the second computer system are forwarded to the first computer system.

7. The first computer system of claim 6, wherein at least a portion of requests received by the first computer system prior to receiving the application are executed on the second computing system.

8. The first computer system of claim 6, wherein the first computer system and the second computer system are located in different Internet Protocol (“

IP”

) domains.

9. The first computer system of claim 1, wherein the operating system for the second computer system comprises a Linux operating system.

10. The first computer system of claim 1, wherein the instance of the application is executed within an operating system container on the first computer system, the first computer system comprising a plurality of operating system containers executing an operating system for the first computer system.

11. The first computer system of claim 1, wherein the network coupling the first computer system and the second computer system comprises a bandwidth limitation such that an amount of data sent from the second computer system to the first computer system for a predetermined period of time does not exceed the bandwidth limitation.

12. The first computer system of claim 1, wherein the operating system container on the first computer system is bridged to a local subnet of the second computer system, the operating system container receiving an Internet Protocol (“

IP”

) address associated with an IP domain for the second computer system.

13. A computer program product for sharing load on an application, the computer program product including a plurality of computer executable instructions stored on a non-transitory computer readable medium, wherein the instructions are executed by a computer to:
