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. A system for dynamically replicating one or more parent nodes on a network in response to a user request, comprising:

a server coupled to the computer network and including a processor operative for executing machine-readable instructions;

a memory storing machine-readable instructions; and

one or more modules comprising machine-readable instructions stored in the memory that, when executed by the processor, perform the method of;

receiving a user request by a policy manager, said user request for replicating a parent node;

transmitting the user request to an event module by the policy manager for replicating the parent node;

transmitting the user request to a data consistency module, wherein the data consistency module maintains integrity of the data on the parent node;

initiating replication of software on the parent node to a new child node;

communicating with a resource management module to ensure proper utilization of network resources; and

transmitting a routing request to a request routing module for appropriately balancing network load, wherein the request routing module provides optimal routing based on the network resources.

2. The system of claim 1, wherein said request routing module communicates with a network monitoring module to initiate monitoring of the child node.

3. The system of claim 2, wherein said network monitoring module communicates network changes to the policy manager, such that in response the policy manager adjusts future replication requests in accordance with availability of the network resources.

4. The system of claim 3, wherein the resource management module communicates with a billing module, said billing module utilizing information communicated by said resource management module to bill customers for usage of the network.

5. The system of claim 4, wherein the policy manager is coupled to a customer configuration module, said customer configuration module enabling the customers to configure their usage criteria.

6. The system of claim 5, wherein said application replication module is coupled to the configuration management module, the configuration management module providing appropriate values to the configuration files of the software being replicated.

7. A non-transitory computer-readable storage medium having computer-executable instructions, the computer-executable instructions, when executed on a server including a computer processor coupled to a network comprising more than one node, perform steps for dynamically replicating one or more nodes on a network in response to a user request, comprising:

receiving at the server a user request by a policy manager, said user request for replicating a parent node;

transmitting the user request from the server to an event module by the policy manager for replicating the parent node;

transmitting the user request from the server to a data consistency module, wherein the data consistency module maintains integrity of the data on the parent node;

initiating replication within the server of software on the parent node to a new child node;

communicating between the server and a resource management module to ensure proper utilization of network resources; and

transmitting a routing request from the server to a request routing module for appropriately balancing network load, wherein the request routing module provides optimal routing based on the network resources.

8. The computer-readable storage medium of claim 7, wherein said request routing module communicates with a network monitoring module to initiate monitoring of the child node.

9. The computer-readable storage medium of claim 8, wherein said network monitoring module communicates network changes to the policy manager, such that in response the policy manager adjusts future replication requests in accordance with availability of the network resources.

10. The computer-readable storage medium of claim 9, wherein the resource management module communicates with a billing module, said billing module utilizing information communicated by said resource management module to bill customers for usage of the network.

11. The computer-readable storage medium of claim 10, wherein the policy manager is coupled to a customer configuration module, said customer configuration module enabling the customers to configure their usage criteria.

12. The computer-readable storage medium of claim 11, wherein said application replication module is coupled to the configuration management module, the configuration management module providing appropriate values to the configuration files of the software being replicated.
