Abstract

Systems and methods for testing and deploying an update are provided. A first server can execute a current version of an application in a production environment. A client communication from a client to the first server can be identified. The client communication can be transmitted to a second server in the production environment. The second server can be executing an updated version of the application. A first response to the client communication from the first server and a second response to the client communication from the second server can be received. The first response from the first server can be compared with the second response from the second server to determine whether the updated version of the application is compatible with the production environment.

Claims

determining whether the updated version of the application is compatible with the production environment in view of the identified difference, wherein the updated version is determined to be compatible with the production environment when the identified difference is allowable under a comparing rule set; and

transmitting, by the processing device, to the client either the first response or the second response in view of the determination of whether the updated version of the application is compatible with the production environment, wherein the second response is transmitted to the client in response to determining that the updated version of the application is compatible.

2. The method of claim 1, further comprising:

intercepting the client communication from the client; and

replicating the client communication from the client.

3. The method of claim 1, further comprising:

determining that the updated version of the application is incompatible with the production environment when the identified difference between the first response from the first server and the second response from the second server is impermissible under the comparing rule set.

4. The method of claim 1, further comprising:

prompting a system administrator of the difference between the first response from the first server and the second response from the second server;

obtaining compatibility input from the system administrator; and

deactivating the first server in the production environment when the compatibility input from the system administrator indicates that the difference between the first response from the first server and the second response from the second server is allowable.

5. The method of claim 1 further comprising, updating the current version of the application to the updated version of the application, wherein the updating comprises:

deactivating the first server in response to determining that the updated version of the application is compatible with the production environment; and

activating the second server.

6. The method of claim 1 further comprising:

receiving a plurality of responses from the first server and a plurality of responses from the second server;

comparing the plurality of responses from the first server with the plurality of responses from the second server to determine whether the updated version of the application is compatible with the production environment; and

deactivating the first server in the production environment when the updated version of the application is compatible with the production environment.

7. The method of claim 1 further comprising:

receiving a plurality of updates to the application;

placing the plurality of updates to the application in an update queue; and

installing each of the plurality of updates to the second server.

8. A system, comprising:

a memory; and

a processing device, operatively coupled with the memory, to;

receive a client communication from a client in a production environment;

transmit the client communication to a first server and to a second server, the first server being in the production environment and comprising a current version of an application and the second server comprising an updated version of the application;

receive a first response to the client communication from the first server and a second response to the client communication from the second server;

compare the first response from the first server with the second response from the second server to identify a difference;

determining whether the updated version of the application is compatible with the production environment in view of the identified difference, wherein the updated version is determined to be compatible with the production environment when the identified difference is allowable under a comparing rule set; and

transmit to the client either the first response or the second response in view of the determination of whether the updated version of the application is compatible with the production environment, wherein the second response is transmitted to the client in response to determining that the updated version of the application is compatible.

9. The system of claim 8, the processing device further to:

intercept the client communication from the client; and

replicate the client communication from the client.

10. The system of claim 8, wherein the processing device further to:

determine that the updated version of the application is incompatible with the production environment when the identified difference between the first response from the first server and the second response from the second server is impermissible under the comparing rule set.

11. The system of claim 8, wherein the processing device is further to:

prompt a system administrator of the difference between the first response from the first server and the second response from the second server;

obtain compatibility input from the system administrator; and

deactivate the first server in the production environment when the compatibility input from the system administrator indicates that the difference between the first response from the first server and the second response from the second server is allowable.

12. The system of claim 8, wherein the processing device is further to:

update the current version of the application to the updated version of the application;

deactivate the first server in response to determining that the updated version of the application is compatible with the production environment; and

activate the second server.

13. The system of claim 12, wherein the current version of the application is updated using a patch, wherein the patch comprises script for installing the patch.

14. The system of claim 8, wherein the processing device further to:

receive a plurality of updates to the application;

place the plurality of updates to the application in an update queue; and

install each of the plurality of updates to the second server.

15. A non-transitory computer readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

receive a client communication from a client in a production environment;

transmit the client communication to a first server and to a second server, the first server being in the production environment and comprising a current version of an application and the second server comprising an updated version of the application;

receive a first response to the client communication from the first server and a second response to the client communication from the second server;

compare, by the processing device, the first response from the first server with the second response from the second server to identify a difference;

determine, by the processing device, whether the updated version of the application is compatible with the production environment in view of the difference, wherein the updated version of the application is compatible with the production environment when the identified difference is allowable under a comparing rule set; and
