Abstract

An embodiment may involve a computational instance disposed within a remote network management platform. The computational instance may contain queues and facilitate the execution of applications. Communication between the computational instance and a managed network may involve: (i) selecting, by a particular application, a particular output queue; (ii) writing, by the particular application, a unit of work generated by the particular application to the particular output queue; (iii) providing, by particular output queue, the unit of work to a particular proxy server application; (iv) retrieving, by a particular input queue, a result from the particular proxy server application, where the result represents an outcome of the particular proxy server application carrying out the unit of work, and where the particular input queue is associated with the particular output queue; and (v) retrieving, by the particular application, the result from the particular input queue.

First claim

What is claimed is:

1. A system comprising:
one or more server computing devices configured to host a computational instance and disposed within a remote network management platform, wherein the remote network management platform is configured to manage a managed network via the computational instance, wherein the computational instance maintains a plurality of queues and executes a plurality of applications, wherein each of the plurality of applications is configured to communicate with one or more of a plurality of proxy server applications executing within the managed network by way of one or more of the plurality of queues, the communication comprising:
selecting, by a particular application of the plurality of applications, a particular output queue of the plurality of queues;
writing, by the particular application, a unit of work generated by the particular application to the particular output queue;
providing, by the particular output queue, the unit of work to a particular proxy server application of the plurality of proxy server applications;
retrieving, by a particular input queue of the plurality of queues, a result from the particular proxy server application, wherein the result represents an outcome of the particular proxy server application carrying out the unit of work, and wherein the particular input queue is associated with the particular output queue; and
retrieving, by the particular application, the result from the particular input queue.

2. The system of claim 1 , wherein there is a one-to-one relationship between the plurality of proxy server applications and the plurality of queues, and wherein each queue of the plurality of queues is configured to use a respectively dedicated proxy server application of the plurality of proxy server applications to communicate with the plurality of applications.

3. The system of claim 1 , wherein there is a one-to-one relationship between the plurality of applications and the plurality of queues, and wherein each of the plurality of applications uses a respectively dedicated queue of the plurality of queues to communicate with the plurality of proxy server applications.

4. The system of claim 1 , wherein each of the plurality of queues is associated with a respective priority, and wherein writing the unit of work generated by the particular application in the particular output queue is based on matching a priority of the unit of work with the respective priority associated with the particular output queue.

5. The system of claim 4 , wherein a time at which the particular output queue provides the unit of work to the particular proxy server application is based on the respective priority associated with the particular output queue.

6. The system of claim 1 , wherein the particular input queue is configured to retrieve a plurality of results from the particular proxy server application, wherein the plurality of results do not include duplicate results from the particular proxy server application.

7. The system of claim 1 , wherein the particular input queue is configured to retrieve a plurality of results from the particular proxy server application, wherein the plurality of retrieved results include merged results of partially-overlapping results into a smaller number of results.

8. The system of claim 1 , wherein the particular input queue is configured to retrieve the result from the particular proxy server application, wherein the result is split into two or more results in response to detection of the result exceeding a predetermined size limit, wherein the two or more split results do not exceed the predetermined size limit.

9. A method comprising:
selecting, by a particular application of a plurality of applications, a particular output queue of a plurality of queues, wherein a computational instance disposed within a remote network management platform maintains the plurality of queues and executes the plurality of applications, wherein each of the plurality of applications is configured to communicate, by way of one or more of the plurality of queues, with one or more of a plurality of proxy server applications executing within a managed network, wherein the remote network management platform manages the managed network via the computational instance;
writing, by the particular application, a unit of work generated by the particular application to a particular output queue of the plurality of queues;
provide, by the particular output queue, the unit of work to a particular proxy server application of the plurality of proxy server applications;
retrieving, by a particular input queue of the plurality of queues, a result from the particular proxy server application, wherein the result represents an outcome of the particular proxy server application carrying out the unit of work, and wherein the particular input queue is associated with the particular output queue; and
retrieving, by the particular application, the result from the particular input queue.

10. The method of claim 9 , wherein there is a one-to-one relationship between the plurality of proxy server applications and the plurality of queues.

11. The method of claim 10 , wherein each queue of the plurality of queues is configured to use a respectively dedicated proxy server application of the plurality of proxy server applications to communicate with the plurality of applications.

12. The method of claim 9 , wherein there is a one-to-one relationship between the plurality of applications and the plurality of queues.

13. The method of claim 12 , wherein each of the plurality of applications uses a respectively dedicated queue of the plurality of queues to communicate with the plurality of proxy server applications.

14. The method of claim 9 , wherein each of the plurality of queues is associated with a respective priority, and wherein writing the unit of work generated by the particular application in the particular output queue is based on matching a priority of the unit of work with the respective priority associated with the particular output queue.

15. The method of claim 14 , wherein a time at which the particular output queue provides the unit of work to the particular proxy server application is based on the respective priority associated with the particular output queue.

16. The method of claim 9 , wherein the particular input queue is configured to retrieve a plurality of results from the particular proxy server application, wherein the plurality of retrieved results include merged results of partially-overlapping results into a smaller number of results.

17. The method of claim 9 , wherein the particular input queue is configured to retrieve the result from the particular proxy server application, wherein the result is split into two or more results in response to detection of the result exceeding a predetermined size limit, wherein the two or more split results do not exceed the predetermined size limit.

18. An article of manufacture comprising a tangible, non-transitory, computer-readable medium, having stored thereon program instructions that, upon execution by a computing system, cause the computing system to perform operations comprising:
selecting, by a particular application of a plurality of applications, a particular output queue of a plurality of queues, wherein a computational instance disposed within a remote network management platform maintains the plurality of queues and executes the plurality of applications, wherein each of the plurality of applications is configured to communicate, by way of one or more of the plu
