Secured computing system

At a work scheduling computing device, a method, comprising:

• receiving a work request from a client device;
• validating the work request to determine that the work request is authorized;
• in response to determining that the work request is authorized, encrypting the work request to form a signed work request and depositing the signed work request in a work depository for discovery by an authorized local agent;
• receiving a polling query from the authorized local agent, the polling query polling for work compatible with a work context of the authorized local agent;
• and
• sending a response to the polling query identifying a job within the work context.

A local agent computing device, comprising:

• a processor;
• and
• memory holding instructions executable by the processor to:
• send to a remote work scheduling computing device a work context of the local agent computing device, the work context describing a set of work that the local agent is configured to execute;
• in response to sending the work context, receive a location of a remote work depository;
• send a polling query to the location of the remote work depository, the polling query querying the remote work depository for work compatible with the work context;
• receive a response to the polling query from the remote work depository identifying a job within the work context, the job being requested by a computing device other than the remote work scheduling computing device;
• and
• execute the job.
