Managing resource allocation in a software-defined system
Resource allocation can be managed in a software-defined system. For example, a computing device can receive, for a container in a software-defined system, a container limit specifying a maximum value for the container. The computing device can receive, for the container, one or more benefit functions that assign a weight for the resource in the software-defined system. The computing device can determine a value for a resource is less than the container limit. In response to determining the value for the resource is less than the container limit, the computing device can allocate the resource to the container based on the weight from the one or more benefit functions.
1. A system comprising:
a processor; and
a memory including instructions that are executable by the processor for causing the processor to:
receive, for a first container in a software-defined system, a container limit specifying a maximum value for obtaining resources for executing the first container;
receive, for the first container, one or more benefit functions that assign a weight to a resource corresponding to an expected performance benefit for the first container using the resource in the software-defined system;
determine that the weight for the resource is greater than a threshold;
determine a first value for using the resource for the first container outside of a container group is less than the container limit;
assign the first container and a second container to the container group;
determine a second value for using the resource for the first container in the container group is less than the first value for using the resource for the first container outside of the container group;
in response to determining the second value is less than the first value, allocate the resource to the first container in the container group; or
determine a third value for using the resource for the first container in the container group exceeds the first value for using the resource for the first container outside of the container group;
in response to determining the first value for using the resource for the first container is less than the container limit, the weight for the resource is greater than the threshold, and that the third value exceeds the first value, allocate the resource to the first container outside of the container group; and
in response to allocating the resource to the first container, activate the first container to execute using the resource.
2. The system of claim 1 , wherein the memory further includes instructions that are executable by the processor for causing the processor to:
determine the first value for using the resource for the first container exceeds the container limit; and
in response to determining the first value exceeds the container limit, deactivate the first container.
3. The system of claim 2 , wherein the memory further includes instructions that are executable by the processor for causing the processor to:
determine a subsequent value for using the resource for the first container is less than the container limit; and
in response to determining the subsequent value is less than the container limit, reactivate the first container.
4. The system of claim 1 , wherein the memory further includes instructions that are executable by the processor for causing the processor to adjust the first value for using the resource for the first container based on an availability of the resource among a plurality of resources in the software-defined system.
5. The system of claim 1 , wherein the one or more benefit functions comprise a static function, a dynamic function that assigns the weight for each resource based on additional resources associated with the first container, or a machine-learning function, and wherein the weight represents an expected performance enhancement provided to the first container by the resource.
6. A computer-implemented method comprising:
receiving, for a first container in a software-defined system, a container limit specifying a maximum value for obtaining resources for executing the first container;
receiving, for the first container, one or more benefit functions that assign a weight to a resource corresponding to an expected performance benefit for the first container using the resource in the software-defined system;
determining that the weight for the resource is greater than a threshold;
determining a first value for using the resource for the first container outside of a container group is less than the container limit;
assigning the first container and a second container to the container group;
determining a second value for using the resource for the first container in the container group is less than the first value for using the resource for the first container outside of the container group;
in response to determining the second value is less than the first value, allocating the resource to the first container in the container group; or
determining a third value for using the resource for the first container in the container group exceeds the first value for using the resource for the first container outside of the container group;
in response to determining the first value for using the resource for the first container is less than the container limit, the weight for the resource is greater than the threshold, and that the third value exceeds the first value, allocating the resource to the first container outside of the container group; and
in response to allocating the resource to the first container, activating the first container to execute using the resource.
7. The method of claim 6 , further comprising:
determining the first value for using the resource for the first container exceeds the container limit; and
in response to determining the first value exceeds the container limit, deactivating the first container.
8. The method of claim 7 , further comprising:
determining a subsequent value for using the resource for the first container is less than the container limit; and
in response to determining the subsequent value is less than the container limit, reactivating the first container.
9. The method of claim 6 , further comprising adjusting the first value for using the resource for the first container based on an availability of the resource among a plurality of resources in the software-defined system.
10. The method of claim 6 , wherein the one or more benefit functions comprise a static function, a dynamic function that assigns the weight for each resource based on additional resources associated with the first container, or a machine-learning function, and wherein the weight represents an expected performance enhancement provided to the first container by the resource.
11. A non-transitory computer-readable medium comprising program code that is executable by a processor for causing the processor to:
receive, for a first container in a software-defined system, a container limit specifying a maximum value for obtaining resources for executing the first container;
receive, for the first container, one or more benefit functions that assign a weight to a resource corresponding to an expected performance benefit for the first container using the resource in the software-defined system;
determine that the weight for the resource is greater than a threshold;
determine a first value for using the resource for the first container outside of a container group is less than the container limit;

determine a second value for using the resource for the first container in the container group is less than the first value for using the resource for the first container outside of the container group;
in response to determining the second value is less than the first value, allocate the resource to the first container in the container group; or

in response to allocating the resource to the first container, activate the first container to execute using the resource.
12. The non-transitory computer-readable medium of claim 11 , further comprising program code that is executable by the processor for causing the processor to adjust the first value for using the resource for the first container based on an availability of the resource among a plurality of resources in the software-defined system.
