Abstract

A web service management process includes receiving, by a job server, a request for a web service, sending a request to register a job corresponding to the web service to an administrative service application, and creating, via the administrative service application, a job proxy resource for the job. The job proxy resource is configured to monitor execution of the job. A uniform resource identifier of the job proxy resource is sent to the job server. The process also includes sending, by the job server, information about job lifecycle events, progress, and a request for a current state of administrator actions on a job proxy of the job to the administrative service application. The administrative service application modifies the current state of the job proxy via commands received from an administrative client. The process further includes transmitting the current state of the job proxy to the job server.

transmitting the current state of the job, via the administrative service application, to the one of the plurality of job servers, wherein each of the plurality of job servers are configured to communicate with the administrative service application via an application programming interface;

wherein each of the plurality of job servers are configured to periodically request the current state of the job proxy resource from the administrative service application; and

wherein upon determining the current state of the job proxy resource is not normal, placing the proxy job resource in an aborted state and notifying the administrative service application of the aborted state, the administrative service application providing the administrative client with access to the current state.

2. The method of claim 1, further comprising:

receiving, by the administrative service application, a request from the administrative client for currently running jobs executing on the plurality of job servers that include the one of the plurality of job servers subject to the request for a web service;

3. The method of claim 2, further comprising:

responsive to receiving the request to modify a state of at least one currently running job proxies of the currently running jobs, the method includes;

modifying a state of the job proxy resource of the job to ‘

abort-requested;

’ and

upon receiving a request from the one of the plurality of job servers for the current state of the job;

transmitting, via the administrative service application, the state of the job proxy resource of the job to the one of the plurality of job servers;

modifying the state of the job proxy to ‘

aborted’

by the one of the plurality of job servers; and

notifying a client system that initially requested the web service of the aborted state of the job.

4. The method of claim 3, wherein the request from the administrative client to modify a state of at least one of the currently running jobs is transmitted to the administrative service application via an administrative user interface.

5. The method of claim 1, wherein the application programming interface is a representational state transfer service.

6. A system for providing web service management, comprising:

a load balancer;

a plurality of job servers configured to execute requests for a web service;

an administrative client system computer; and

a monitor computer system executing an administrative service application in communication with each of the plurality of job servers and the administrative client system, the system implementing a method, comprising;

receiving, by the load balancer, a request for the web service and forwarding the request for the web service to one of the plurality of the job servers;

sending a request to register a job corresponding to the web service to the administrative service application;

creating, via the administrative service application, a job proxy resource for the job, the job proxy resource configured to monitor execution of the job, and sending a uniform resource identifier of the job proxy resource to the one of the plurality of job servers;

configuring a uniform resource identifier of the administrative service application on the one of the plurality of job servers, the one of the plurality of job servers sending the request to the administrative service application to register the job via the uniform resource locator;

sending, by the one of the plurality of job servers, information about job lifecycle events and progress and a request for a current state of administrator actions on a job proxy of the job to the administrative service application via the uniform resource identifier and the job proxy resource, the administrative service application modifying the current state of the job proxy via commands received from an administrative client; and

transmitting the current state of the job proxy, via the administrative service application, to the job servers, wherein each of the plurality of job servers are configured to communicate with the administrative service application via an application programming interface;

wherein each of the plurality of job servers are configured to periodically request the current state of the job proxy resource from the administrative service application; and

wherein upon determining the current state of the job proxy resource is not normal, placing the proxy job resource in an aborted state and notifying the administrative service application of the aborted state, the administrative service application providing the administrative client with access to the current state.

7. The system of claim 6, wherein the method further comprises:

receiving, by the administrative service application, a request from the administrative client for currently running jobs executing on the plurality of job servers that include the one of the plurality of job servers subject to the request for a web service;

returning a list of the currently running jobs to the administrative client; and

receiving, at the administrative service application, a request from the administrative client to modify a state of at least one currently running job proxy of the currently running jobs.

8. The system of claim 7, wherein the method further comprises:

responsive to receiving the request to modify a state of at least one of the currently running job proxies, the method includes;

modifying a state of the job proxy resource of the job to ‘

abort-requested;

’ and

upon receiving a request from the one of the plurality of job servers for the current state of the job proxy;

transmitting, via the administrative service application, the state of the job proxy resource of the job to the one of the plurality of job servers;
