Abstract

Clients access compute resources in a data center organized in logical clusters. A cluster level quota governs access to the compute resources, regardless of the location of the resources which can be part of multiple computers or part of multiple data centers. The cluster level quota can manage allocation and usage of storage, memory, and CPU resources in multi-tenant data center environments. A user requests a computing resource from a logical compute cluster in a data center of host machines hosting virtual machines. According to permissions associated with the user for the logical compute cluster and a cluster quota, the system grants access to the computing resource to the user in response to the request when the cluster quota permits an expected use of the computing resource according to the request.

Claims

1. A method comprising:

receiving, by a processing device, a request to access a computing resource in a data center comprising a plurality of host machines hosting a plurality of virtual machines;

identifying a logical compute cluster associated with the computing resource, permissions associated with accessing the logical compute cluster, and a plurality of different concurrently enforced cluster quotas for the logical compute cluster, wherein the logical compute cluster comprises at least one of a subset of the plurality of virtual machines or the plurality of host machines;

identifying, in view of the request, a first set of the plurality of different concurrently enforced cluster quotas applicable to the request; and

upon determining that the first set of the plurality of different concurrently enforced cluster quotas permits an expected use of the computing resource according to the request, granting, by the processing device, access to the computing resource to the user in response to the request.

2. The method of claim 1, wherein the computing resource comprises at least one of memory, processor, storage, virtual machine, or network bandwidth.

3. The method of claim 1, wherein the cluster quota is associated with a user group.

4. The method of claim 1, further comprising:

recording the request and associated use of the computing resource in a log.

5. The method of claim 1, further comprising:

monitoring usage of the computing resource;

determining that usage of the computing resource is within a threshold of a maximum usage indicated by the first set of the plurality of different concurrently enforced cluster quotas; and

sending an alert that usage of the computing resources is within the threshold.

6. The method of claim 1, further comprising:

monitoring usage of the computing resource;

determining that the usage of the computing resource exceeds a maximum usage indicated by the first set of the plurality of different concurrently enforced cluster quotas; and

sending an alert that usage of the computing resource exceeds the maximum usage.

7. The method of claim 6, further comprising:

denying an additional request for the computing resource until the usage is below the maximum usage.

8. The method of claim 6, further comprising:

determining that the usage of the computing resource is within a grace limit; and

sending a notification indicating that the usage of the computing resource is within the grace limit.

9. A system comprising:

a memory to store a plurality of different concurrently enforced cluster quotas; and

a processing device operatively coupled to the memory, the processing device to;

receive a request for compute resources in a logical cluster within a data center, wherein the user is associated with the logical cluster, and wherein the logical cluster is associated with the plurality of different concurrently enforced cluster quotas;

calculate an expected resource quantity to satisfy the request;

determine that the logical cluster has sufficient available compute resources to satisfy the request in view of the expected resource quantity;

identify, in view of the request, a first set of the plurality of different concurrently enforced cluster quotas applicable to the request;

determine that the first set of the plurality of different concurrently enforced cluster quotas allows usage of the expected resource quantity in the logical cluster; and

grant access to the computing resource in the logical cluster in response to the request.

10. The system of claim 9, wherein the first set of the plurality of different concurrently enforced cluster quotas is associated with a grace limit allowing resource usage beyond a maximum indicated by the identified at least one of the plurality of different concurrently enforced cluster quotas.

11. The system of claim 10, the processing device to:

determine that the expected resource quantity exceeds the first set of the plurality of different concurrently enforced cluster quotas and is within the grace limit;

generate a notification that the expected resource quantity exceeds the first set of the plurality of different cluster quotas; and

grant access to the computing resource under the grace limit.

12. The system of claim 9, wherein the access is granted to a user that is different from an administrator who created the plurality of different concurrently enforced cluster quotas.

13. The system of claim 9, wherein the plurality of different cluster quotas indicate separate respective compute resource quotas for different compute resource types.

14. The system of claim 9, wherein the request is associated with an event that consumes the compute resources.

15. A non-transitory computer-readable storage medium comprising instructions which, when executed by a processing device, cause the processing device to:

receive, by the processing device, a request from to access a computing resource in a logical cluster in a data center, wherein the logical cluster is associated with a plurality of different concurrently enforced cluster quotas;

identify, in view of the request, a first set of the plurality of different concurrently enforced cluster quotas applicable to the request;

identify, by the processing device, that fulfilling the request would exceed the first set of the plurality of different cluster quotas;

send a notification indicating that fulfilling the request would exceed the first set of the plurality of different concurrently enforced cluster quotas;

receive a response to the notification; and

fulfill the request in view of the response.

16. The non-transitory computer-readable storage medium of claim 15, wherein the response comprises an instruction to expand the first set of different concurrently enforced cluster quotas.

17. The non-transitory computer-readable storage medium of claim 15, wherein the response comprises an instruction to reduce an amount of the computing resource requested.

18. The non-transitory computer-readable storage medium of claim 15, wherein the response comprises an authorization to delay fulfillment of the request until fulfilling the request would be within the first set of the plurality of different concurrently enforced cluster quotas.

19. The non-transitory computer-readable storage medium of claim 15, wherein to fulfill the request, the processing device is further to fulfill a first portion of the request and denying a second portion of the request.

20. The non-transitory computer-readable storage medium of claim 15, wherein the request relates to an event for which computing resources are required.
