Abstract

A method for facilitating the uploading of web applications to a cloud computing environment utilizes hashes or fingerprints of each file in a web application. Prior to submitting all the files of a web application to the cloud computing environment for deployment, fingerprints of each file in the web application are transmitted to the cloud computing environment to assess whether the cloud computing environment may already possess the file as a result of receiving it from previously uploaded web applications.

Claims

1. A method for receiving a web application for deployment in a cloud computing environment, the method comprising the steps of:

receiving a list of hash values from a development environment, wherein each hash value corresponds to a file in a web application package to be submitted to the cloud computing environment;

comparing the list of hash value with a local list of hash values corresponding to locally stored files from previously submitted web applications;

identifying a subset of files in the web application package, wherein each file in the subset does not have a corresponding entry in the local list of hash values;

requesting the subset of files from the development environment; and

receiving the subset of files.

2. The method of claim 1, further comprising the step of storing the received subset of files in a local storage.

3. The method of claim 2, wherein the local storage is a network storage array network.

4. The method of claim 2, further comprising the step of updating the local list of hash values with hash value entries for the received subset of files.

5. The method of claim 1, wherein the list of hash values further comprises a corresponding list of file sizes for each file in the web application package, the local list of hash values further comprises a corresponding list of file sizes for each file stored in the local storage, and wherein the comparing step further comprises comparing the file sizes in the list of hash values with the file sizes in the local list of hash values.

6. The method of claim 1, wherein the web application package is a WAR file.

7. The method of claim 1, wherein the development environment is an IDE.

8. A computer-readable storage medium including instructions that, when executed on a computer processor, causes the computer processor to receive a web application for deployment in a cloud computing environment, by performing the steps of:

receiving a list of hash values from a development environment, wherein each hash value corresponds to a file in a web application package to be submitted to the cloud computing environment;

comparing the list of hash value with a local list of hash values corresponding to locally stored files from previously submitted web applications;

identifying a subset of files in the web application package, wherein each file in the subset does not have a corresponding entry in the local list of hash values;

requesting the subset of files from the development environment; and

receiving the subset of files.

9. The computer-readable storage medium of claim 8, further comprising instructions to perform the step of storing the received subset of files in a local storage.

10. The computer-readable storage medium of claim 9, wherein the local storage is a network storage array network.

11. The computer-readable storage medium of claim 9, further comprising instructions to perform the step of updating the local list of hash values with hash value entries for the received subset of files.

12. The computer-readable storage medium of claim 8, wherein the list of hash values further comprises a corresponding list of file sizes for each file in the web application package, the local list of hash values further comprises a corresponding list of file sizes for each file stored in the local storage, and wherein the comparing step further comprises comparing the file sizes in the list of hash values with the file sizes in the local list of hash values.

13. The computer-readable storage medium of claim 8, wherein the web application package is a WAR file.

14. The computer-readable storage medium of claim 8, wherein the development environment is an IDE.

15. A method for submitting a web application for deployment in a cloud computing environment, the method comprising the steps of:

generating a list of hash values, wherein each hash value corresponds to a file in a web application package to be submitted to the cloud computing environment;

transmitting the list of hash values to the cloud computing environment;

receiving a subset of files in the web application package, wherein each file in the subject has not been stored in the cloud computing environment, based upon a comparison by the cloud computing environment of the transmitted list of hash value with a second list of hash values maintained by the cloud computing environment and corresponding to files stored by the cloud computing environment in a local storage, wherein the stored files are received from previously submitted web applications; and

providing the subset of files to the cloud computing environment.

16. The method of claim 15, wherein the list of hash values further comprises a corresponding list of file sizes for each file in the web application package, the second list of hash values further comprises a corresponding list of file sizes for each file stored in the local storage, and the comparison further comprises comparing the file sizes in the list of hash values with the file sizes in the second list of hash values.

17. The method of claim 15, wherein the web application package is a WAR file.

18. The method of claim 15, performed in an IDE.

19. The method of claim 15, wherein the providing step comprises transmitting references to the subset of files to the cloud computing environment.

20. The method of claim 19, wherein the references are URLs.
