Abstract

Systems and methods are presented for providing resources by way of a platform as a service in a distributed computing environment to perform a job. Resources of the system, job performing on the system, and schedulers of the jobs performing on the system are decoupled in a manner that allows a job to easily migrate among resources. It is contemplated that the migration of jobs from a first pool of resource to a second pool of resource is performed by the system without human intervention. The migration of a job may utilize different schedulers for the different resources. Further, it is contemplated that a pool of resources may automatically allocate additional or fewer resources in response to a migration of a job.

Claims

1. A computer-implemented method for providing resources in a distributed computing environment, comprising:

receiving a work item from a user;

creating a job from the work item;

automatically, with a processor and memory, allocating at least a first virtual machine to a first pool;

scheduling the job on the first pool;

initiating the job on the first pool;

reassigning the job to a second pool comprised of at least a second virtual machine; and

initiating the job on the second pool.

2. The method of claim 1, wherein the scheduling of the job on the first pool is performed, at least in part utilizing a first scheduler that is not utilized to schedule the job on the second pool.

3. The method of claim 1 further comprising detecting a failure in the first pool.

4. The method of claim 3, wherein the reassigning of the job is in response to the detected failure within the first pool.

5. The method of claim 1, wherein the reassigning of the job allows for a continuation of the job on the second pool.

6. The method of claim 1, wherein the reassigning of the job is in response to a load balancing determination of the first pool.

7. The method of claim 1, wherein the reassigning of the job migrates the job from the first pool to the second pool.

8. The method of claim 1, wherein the reassigning is managed by a high-level location service in communication with one or more task location services associated with the first pool.

9. The method of claim 1, wherein the reassigning the job allows for migration of the job from the first pool to the second pool without user intervention.

10. The method of claim 1, wherein the second virtual machine is in a different geographic location from the first virtual machine.

11. The method of claim 1, wherein the second virtual machine is in a different task tenant from the first virtual machine.

12. The method of claim 1, wherein the scheduling the tasks for the job on the first pool is comprised of running at least one task on a virtual machine associated with the first pool.

13. The method of claim 1, wherein the first pool is comprised of two or more task tenants.

14. The computer-storage media of claim 1, wherein the second virtual machine is allocated to the second pool based, in part, on a specification associate with the work item.

15. The computer-storage media of claim 1, wherein the first virtual machine and the second virtual machine utilize different physical processors.

16. One or more computer-storage media storing computer-useable instructions that, when executed by a computing device having a processor and memory, perform a method for providing resources in a distributed computing environment, comprising:

scheduling, with a first scheduler, a job on a first pool of resource in the distributed computing environment;

initiating the job on the first pool;

determining, without a user intervention, the job is to migrate from the first pool to a second pool within the distributed computing environment;

automatically scheduling, with a second scheduler using a processor and memory, the job on the second pool; and

initiating the job on the second pool.

17. The computer-storage media of claim 16, wherein the first pool and the second pool are selected by a high-level location service that is in communication with a task location service associated with the first scheduler and in communication with a task location service associated with the second scheduler.

18. The computer-storage media of claim 16, wherein the determination that the job is to migrate is based, at least in part, on a load balancing determination of the first pool or in response to a failure of one or more components utilized by the first pool.

19. The computer-storage media of claim 16, wherein a portion of tasks associated with the job migrate to the second pool while another portion of the tasks continue to be scheduled on the first pool.

20. A computer-implemented method for providing resources in a distributed computing environment, comprising:

receiving, at a task location service, a work item from a user associated with a task account in the distributed computing environment;

automatically allocating, with a pool server associated with the task location service, a first virtual machines of the distributed computing environment to a first pool;

scheduling a first job on the first pool, wherein the first job is comprised of one or more tasks associated with the work item;

automatically determining, based on a load balancing evaluation of the first pool, the job is to migrate to a second pool within the distributed computing environment;

migrating at least one task associated with the work item to the second pool; and

scheduling the at least one task on one or more resource of the second pool.
