Abstract

A method and system for building an elastic cloud web server farm. The method includes registering a web application on a serving cloud and copying the web application to a distributed store. A load of the web application is specified, and a plurality of nodes is added for the web application based on the load. A web server corresponding to a node of the plurality of nodes is then initialized. A web request is received from a user and a web server is selected from a list of available web servers to process the web request. The web request is further transmitted to the web server. A web response, based on the web request, is transmitted back to the user. The system includes a central registry, a distributed store, a process coordinator, one or more web servers, and a router.

Claims

1. A method of building an elastic cloud web server farm, the method comprising:

registering a web application on a serving cloud;

copying the web application to a distributed store;

specifying a load of the web application;

adding a plurality of nodes for the web application based on the load;

initializing a web server corresponding to a node of the plurality of nodes;

receiving a web request from a user;

selecting the web server from a list of available web servers to process the web request;

transmitting the web request to the web server; and

transmitting a web response, based on the web request, to the user.

2. The method as claimed in claim 1 and further comprising:

processing a plurality of web applications simultaneously.

3. The method as claimed in claim 1, wherein specifying the load comprises one of

dynamically handling an increase in the load by increasing number of web servers required for the web application;

and

dynamically handling a decrease in the load by decreasing number of the web servers required for the web application.

4. The method as claimed in claim 1, wherein the plurality of nodes is added in a central registry.

5. The method as claimed in claim 4 and further comprising:

mapping the web application to the web server corresponding to the node.

6. The method as claimed in claim 5, wherein the mapping is performed by the central registry.

7. The method as claimed in claim 1, wherein initializing the web server comprises:

determining a port from a predetermined range of ports; and

registering an identifier with the central registry, the identifier being defined with a hostname and port.

8. The method as claimed in claim 1 and further comprising:

maintaining the list of available web servers by a central registry.

9. The method as claimed in claim 1, wherein the web request is retransmitted to another web server from the list of available web servers to handle failure of the web server.

10. The method as claimed in claim 1, wherein registering a web application comprises

packaging the web application using WebARchive.

11. A computer program product stored on a non-transitory computer-readable medium that when executed by a processor, performs a method of building an elastic cloud web server farm, comprising:

registering a web application on a serving cloud;

copying the web application to a distributed store;

specifying a load of the web application;

adding a plurality of nodes for the web application based on the load;

initializing a web server corresponding to a node of the plurality of nodes;

receiving a web request from a user;

selecting the web server from a list of available web servers to process the web request;

transmitting the web request to the web server; and

transmitting a web response, based on the web request, to the user.

12. The computer program product as claimed in claim 11 and further comprising:

processing a plurality of web applications simultaneously.

13. The computer program product as claimed in claim 11, wherein specifying the load comprises one of

dynamically handling an increase in the load by increasing number of web servers required for the web application;

and

dynamically handling a decrease in the load by decreasing number of the web servers required for the web application.

14. The computer program product as claimed in claim 11, wherein the plurality of nodes is added in a central registry.

15. The computer program product as claimed in claim 14 and further comprising:

mapping the web application to the web server corresponding to the node.

16. The computer program product as claimed in claim 15, wherein the mapping is performed by the central registry.

17. The computer program product as claimed in claim 11, wherein initializing the web server comprises:

determining a port from a predetermined range of ports; and

registering an identifier with the central registry, the identifier being defined with a hostname and port.

18. The computer program product as claimed in claim 11 and further comprising:

maintaining the list of available web servers by a central registry.

19. The computer program product as claimed in claim 11, wherein the web request is retransmitted to another web server from the list of available web servers to handle failure of the web server.

20. The computer program product as claimed in claim 11, wherein registering a web application comprises

packaging the web application using WebARchive.

21. A system for building an elastic cloud web server farm, the system comprising:

a central registry that maintains a list of available web servers;

a distributed store that stores a plurality of web applications;

a process coordinator that

registers a web application on a serving cloud;

copies the web application to the distributed store;

specifies a load of the web application;

adds a plurality of nodes for the web application based on the load;

one or more web servers, each web server comprising;

a map web engine that

initializes a web server corresponding to a node of the plurality of nodes;

a router that

receives a web request from a user;

selects the web server from the list of available web servers to process the web request;

transmits the web request to the web server; and

transmits a web response, based on the web request, to the user.

22. The system as claimed in claim 21, wherein the system is built on a cloud computing platform.
