Determining tenant priority based on resource utilization in separate time intervals and selecting requests from a particular tenant based on the priority
Examples relate to accessing resources across multiple tenants. One example enables determination, from a list of requests, a request to perform which accesses a resource, responsive to a determination that the resource on a server is available for use for an application. The request to be performed may be determined, for example, by determining a first priority score for a first tenant associated with a first request based on usage of the resource by the first tenant, wherein the first tenant comprises a first set of users, determining a second priority score for a tenant associated with a second request based on usage of the resource by the second tenant, wherein the second tenant comprises a second set of users, and, responsive to the first priority score being lower than the second priority score, selecting the first request as the request to be performed.

scaling the first metric based on a first multiplier;
determining a second metric representing an amount of usage of the resource by the first tenant during a second time interval other than the first time interval;
scaling the second metric based on a second multiplier other than the first multiplier; and
calculating the first priority score based on the scaled first metric and the scaled second metric; and
determining a second priority score for a second tenant of the plurality of tenants associated with a second request of the list of requests based on usage of the resource by the second tenant, the second tenant comprising a second set of users; and
responsive to the first priority score and the second priority score, selecting the first request as the request to be performed.
2. The storage medium of claim 1 , wherein the instructions to determine the first priority score comprise instructions to:
calculate the first priority score further based on a number of users in the first set of users.

4. The storage medium of claim 1 , wherein the instructions to determine the first priority score comprise instructions to:
calculate the first priority score based on an application priority of the first request, wherein the application priority of the first request indicates an importance of the first request to the application.
5. The storage medium of claim 1 , further comprising instructions executable by the processor to:
receive the first request to access the application from the first tenant;
determine whether the resource to be accessed by the first request is available to perform the first request; and
responsive to the resource not being available to perform the first request, place the first request in the list of requests.
6. The storage medium of claim 5 , further comprising instructions executable by the processor to:
perform the first request responsive to determining that the resource to be accessed by the first request is available to perform the first request.
7. The storage medium of claim 1 , wherein the instructions further comprise instructions to:
vary the first and second multipliers according to time such that the scaled first metric has more influence on the first priority score than the scaled second metric, wherein the first time interval occurs more recently than the second time interval.
8. The storage medium of claim 1 , wherein the instructions further comprise instructions to select the first request based on the first priority score being less than the second priority score.
9. A system comprising:
a processor; and
a memory to store instructions that, when executed by the processor, cause the processor to:
determine, responsive to a resource on a server becoming available for use via an application, a request for the server to perform from a list of requests, wherein the server performing the request comprises the application accessing the resource;
wherein determining the request comprises:
determining a first priority score for a first tenant of a plurality of tenants associated with a first request of the list of requests, wherein the first tenant comprises a first set of users and determining the first priority score comprises:
determining a first metric representing an amount of usage of the resource by the first tenant during a first time interval;
scaling the first metric based on a first multiplier;
determining a second metric representing an amount of usage of the resource by the first tenant during a second time interval other than the first time interval;
scaling the second metric based on a second multiplier other than the first multiplier; and
calculating the first priority score based on the scaled first metric and the scaled second metric;
determining a second priority score for a second tenant of the plurality of tenants, wherein the second priority score is associated with a second set of requests of the list of requests based on usage of the resource by the second tenant, and the second tenant comprises a second set of users; and
responsive to the first priority score and the second priority score, selecting the first request as the request to be performed.
10. The system of claim 9 , wherein the memory further stores instructions that, when executed by the processor, cause the processor to determine, responsive to a second resource on the server becoming available for use via the application, a second request to perform from a second list of requests, wherein the second request comprises a request to access to the second resource.
11. The system of claim 9 , wherein the memory further stores instructions that, when executed by the processor, cause the processor to:
receive the first request to access the application from the first tenant;
determine whether the resource to be accessed by the first request is available to perform the request; and
responsive to the resource not being available to perform the first request, place the first request in the list of requests.
12. The system of claim 9 , wherein the instructions, when executed by the processor, further cause the processor to:
vary the first and second multipliers according to time such that the scaled first metric has more influence on the first priority score than the scaled second metric, wherein the first time interval occurs more recently than the second time interval.
13. A method comprising:
responsive to a resource on a server becoming available for use via an application, determine a request for the server to perform using the application from a list of requests, wherein performing the request comprises accessing the resource,
wherein determining the request from the list of requests comprises:
determining a respective priority score for each tenant of a plurality of tenants, wherein the respective priority score is associated with a request in the list of requests based on usages of the resource by the each tenant in respective time intervals, wherein determining the respective priority score for the each tenant comprises, for a given tenant of the plurality of tenants:
determining a first metric representing an amount of usage of the resource by the given tenant during a first time interval;
scaling the first metric based on a first multiplier;
determining a second metric representing an amount of usage of the resource by the given tenant during a second time interval other than the first time interval;
