Systems, methods, and apparatuses for implementing a scheduler and workload manager with snapshot and resume functionality

Non-transitory computer readable storage media having instructions stored thereupon that, when executed by a system having at least a processor and a memory therein, the instructions cause the system to perform operations including:

• allocating a cache within the memory of the system to store information on behalf of a compute resource discovery engine and a workload discovery engine and a scheduler;
• identifying, via the compute resource discovery engine, a plurality of computing resources available to execute workload tasks and updating the cache specifying the identified computing resources;
• identifying, via the workload discovery engine, pending workload tasks to be scheduled for execution from one or more workload queues and updating the cache with the identified workload tasks;
• and
• executing a scheduler via the processor of the system, wherein the scheduler performs at least the following operations:
• retrieving information from the cache specifying the one or more computing resources available to execute workload tasks and specifying the plurality of workload tasks to be scheduled for execution;
• determining, based on the information from the cache, that a sub-set of the plurality workload tasks are serviceable by identical snapshots of a provisioned computing resource;
• initiating a snapshotting process to generate a snapshot of the provisioned computing resource and force delaying the sub-set of the plurality workload tasks until the snapshot is complete;
• and
• scheduling each of the sub-set of the plurality workload tasks for execution on a different computing resource utilizing replicated copies of the completed snapshot.

A system to implement a scheduling service, wherein the system comprises:

• a processor and a memory to execute instructions at the system;
• a cache allocated within the memory of the system to store information on behalf of a compute resource discovery engine and a workload discovery engine and a scheduler;
• wherein the compute resource discovery engine is to identify a plurality of computing resources available to execute workload tasks and update the cache specifying the identified computing resources;
• wherein the workload discovery engine is to identify pending workload tasks to be scheduled for execution from one or more workload queues and update the cache with the identified workload tasks;
• and
• wherein the scheduler is to retrieve information from the cache specifying the one or more computing resources available to execute workload tasks and specifying the plurality of workload tasks to be scheduled for execution;
• wherein the scheduler is further to determine, based on the information from the cache, that a sub-set of the plurality workload tasks are serviceable by identical snapshots of a provisioned computing resource;
• wherein the scheduler is further to initiate a snapshotting process to generate a snapshot of the provisioned computing resource and force delaying the sub-set of the plurality workload tasks until the snapshot is complete;
• and
• wherein the scheduler is to schedule each of the sub-set of the plurality workload tasks for execution on a different computing resource utilizing replicated copies of the completed snapshot.
