Abstract

An apparatus, method and system to enable dynamic replication of Web servers across a wide area in response to access patterns by Web clients as well as in response to customer requests. The method for dynamically replicating one or more parent nodes on a network in response to a user request by a policy manager. The policy manager transmits the user request to an event module. The event module transmits the user request to a data consistency module, wherein the data consistency module maintains integrity of the data on the parent node. The event system communicates with a resource management module to ensure proper utilization of network resources, and transmits the routing request to a request routing module for appropriately balancing the network load. The request routing module is capable of providing optimal routing based on the network resources.

Claims

1-6. -6. (canceled)

7. A method of initiating a replication event on a computer network, comprising:

obtaining a user request message;

determining the fixed resource requirements for all existing applications on the network;

parsing the user request message;

comparing the user request to current setting for the user;

determining appropriate action in response to the user request; and

acting upon user request message.

8. The method of claim 7, wherein the user request is for creation of a new application node.

9. The method of claim 8, further comprising:

comparing the parsed user request to a resource usage list for determining availability of adequate resources;

determining the fixed resource requirement;

creating an installation bill of materials for the application node being added;

generating a user account;

copying files for the application in the installation bill of materials;

obtaining local replacement for tokens used in the bill of materials; and

reconfiguring files for local node.

10. The method of claim 9, wherein creating an installation bill of materials comprises:

determining the appropriate directory for installation;

obtaining the machine specifics;

parsing the file type;

noting and replacing machine specific entries with tokens; and

appending custom entries to the existing bill of materials.

11. The method of claim 7, wherein the user request is for deletion of an existing application node.

12. The method of claim 11, further comprising:

determining whether a process is running on the existing application node;

forcing an update in the data consistency module of the data to be deleted from the existing application node;

reporting unavailability of the existing application node being deleted;

deleting application files from the application node; and

reporting unavailability of data from the application node being deleted to all modules in the network.

13. The method of claim 7, wherein the user request is for turning on of an existing application node that is off.

14. The method of claim 7, wherein the user request is for turning off of an existing application node that is on.

15. The method of claim 7, wherein the user request is for changing the priority levels of an existing application.
