Abstract

Described embodiments provide systems and methods for routing service requests. The system includes a first network of computing devices including a server hosting a service. The system includes a release router in the first network, the release router configured to receive a request for the service, the request forwarded to the release router responsive to resolving a hostname specified in the request using a DNS mapping the hostname to the release router, the hostname associated with the service hosted by the server. The release router is configured to identify a relay agent registered with the release router for debugging the service, the relay agent executed by a test platform in a second network, and to forward the request to the test platform in the second network, wherein the test platform resolves the hostname specified in the request using a local DNS mapping the hostname to a localhost address.

Claims

1. A method of routing service requests, the method comprising:

receiving, by a release router in a first network, a request for a service hosted by a server in the first network, the request forwarded to the release router responsive to resolving a uniform resource locator (“

URL”

) hostname specified in the request using a Domain Name System (“

DNS”

) mapping the URL hostname to the release router, the URL hostname associated with the service hosted by the server;

identifying, by the release router, a relay agent registered with the release router for debugging the service, the relay agent executed by a test platform in a second network; and

forwarding, by the release router, the request to the test platform in the second network, wherein the test platform resolves the URL hostname specified in the request using a local DNS mapping the URL hostname to a localhost address.

2. The method of claim 1, wherein the test platform is a computing device hosting a test instance of the service and configured for debugging the service.

3. The method of claim 1, comprising checking, by the release router, a set of routing rules for debug service requests and identifying the relay agent based on the set of routing rules.

4. The method of claim 3, comprising updating the set of routing rules based on a registration for one of:

the test platform, the relay agent, or a test instance of the service hosted by the test platform.

5. The method of claim 1, further comprising forwarding the request to the test platform in the second network, by the release router, via a service bus external to the second network, wherein the relay agent is registered with the service bus to receive the request.

6. The method of claim 5, further comprising configuring the service bus to forward, to the second network, requests directed to resource identifiers specifying a name for the service, wherein the URL of the received request specifies the name for the service.

7. The method of claim 5, wherein the service bus is situated in the first network.

8. The method of claim 1, further comprising:

receiving, by the release router in the first network, a second request for the service hosted by the server in the first network;

checking, by the release router, a set of routing rules; and

forwarding the second request to the server in the first network responsive to the set of rules.

9. The method of claim 1, wherein the release router is a proxy for the server and hosted on a computing device in the first network.

10. A system for routing service requests, the system comprising:

a first network of computing devices including a server hosting a service; and

a release router in the first network configured to;

receive a request for the service hosted by the server in the first network, the request forwarded to the release router responsive to resolving a uniform resource locator (“

URL”

) hostname specified in the request using a Domain Name System (“

DNS”

) mapping the URL hostname to the release router, the URL hostname associated with the service hosted by the server;

identify a relay agent registered with the release router for debugging the service, the relay agent executed by a test platform in a second network; and

forward the request to the test platform in the second network, wherein the test platform resolves the URL hostname specified in the request using a local DNS mapping the URL hostname to a localhost address.

11. The system of claim 10, wherein the test platform is a computing device hosting a test instance of the service and configured for debugging the service.

12. The system of claim 10, the release router further configured to check a set of routing rules for debug service requests and to identify the relay agent based on the set of routing rules.

13. The method of claim 12, the release router further configured to update the set of routing rules based on a registration for one of:

the test platform, the relay agent, or a test instance of the service hosted by the test platform.

14. The system of claim 10, the release router further configured to forward the request to the test platform in the second network via a service bus external to the second network, wherein the relay agent is registered with the service bus to receive the request.

15. The system of claim 14, wherein the service bus is configured to forward, to the second network, requests directed to resource identifiers specifying a name for the service, and wherein the URL of the received request specifies the name for the service.

16. The system of claim 14, wherein the service bus is situated in the first network.

17. The system of claim 10, the release router further configured to:

receive a second request for the service hosted by the server in the first network;

check a set of routing rules; and

forward the second request to the server in the first network responsive to the set of rules.

18. The system of claim 10, wherein the release router is a proxy for the server and hosted on a computing device in the first network.

19. A non-transitory computer-readable medium storing instructions that cause a processor executing the instructions for a release router in a first network to:

receive a request for a service hosted by a server in the first network, the request forwarded to the release router responsive to resolving a uniform resource locator (“

URL”

) hostname specified in the request using a Domain Name System (“

DNS”

) mapping the URL hostname to the release router, the URL hostname associated with the service hosted by the server;

identify a relay agent registered with the release router for debugging the service, the relay agent executed by a test platform in a second network; and

forward the request to the test platform in the second network, wherein the test platform resolves the URL hostname specified in the request using a local DNS mapping the URL hostname to a localhost address.

20. The non-transitory computer-readable medium of claim 19, further storing instructions that cause the processor executing the instructions to:

check a set of routing rules for debug service requests, the set of routing rules maintained based on a registration for one of;

the test platform, the relay agent, or a test instance of the service hosted by the test platform; and

identify the relay agent based on the set of routing rules.
