System, apparatus and method for cloud resource allocation

A cloud resource allocation apparatus, comprising:

• a storage, storing an orchestrator and providing a waiting queue and a running queue, wherein the orchestrator comprises a resource manager and a job scheduler;
• and
• a processor, coupled to the storage, configured to:
• obtain a plurality of node resource information respectively reported by a plurality of worker nodes through the resource manager;
• and
• parse a job profile of a job request obtained from the waiting queue through the job scheduler and decide to execute a direct resource allocation or an indirect resource allocation for a job to be handled requested by the job request based on the node resource information and the job profile;
• wherein in response to deciding to execute the direct resource allocation, the processor is configured to:
• find a first worker node having an available resource matching the job profile among the worker nodes through the job scheduler;
• dispatch the job to be handled to the first worker node through the resource manager;
• and
• put the job to be handled into the running queue through the job scheduler;
• wherein in response to execute the indirect resource allocation, the processor is configured to:
• through the job scheduler, find a second worker node having a low priority job among the worker nodes, notify the second worker node so that the second worker node backs up an operation mode of the low priority job, and then release resource used by the low priority job;
• put another job request corresponding to the low priority job into the waiting queue through the job scheduler in response to receiving a resource release notification from the second worker node through the resource manager;
• dispatch the job to be handled to the second worker node through the resource manager;
• and
• put the job to be handled into the running queue through the job scheduler.

A cloud resource allocation method, comprising:

• executing the following through a cloud resource allocation apparatus:
• obtaining a plurality of node resource information respectively reported by a plurality of worker nodes;
• and;
• parse a job profile of a job request obtained from a waiting queue and deciding to execute a direct resource allocation or an indirect resource allocation for a job to be handled requested by the job request based on the node resource information and the job profile;
• wherein deciding to execute the direct resource allocation comprises:
• finding a first worker node having an available resource matching the job profile among the worker nodes;
• dispatching the job to be handled to the first worker node;
• and
• putting the job to be handled into a running queue;
• wherein executing the indirect resource allocation comprises:
• finding a second worker node having a low priority job among the worker nodes, notify the second worker node so that the second worker node backs up an operation mode of the low priority job, and then release resource used by the low priority job;
• putting another job request corresponding to the low priority job into the waiting queue in response to receiving a resource release notification from the second worker node;
• dispatching the job to be handled to the second worker node;
• and
• putting the job to be handled into the running queue.
