6. The method of claim 4 , wherein the priority associated with the first application is based on application type.

7. The method of claim 1 , wherein each of the one or more applications is associated with a corresponding default amount of resources.

8. The method of claim 1 , wherein determining the system resource allocation for the one or more applications of the data storage system further comprises:

determining a total amount of available resources for the data storage system; and

determining an amount of resources needed for the one or more core functionalities of the data storage system, wherein the system resource allocation for the one or more applications is based on the determined total amount of available resources for the data storage system and the determined amount of resources needed for the one or more core functionalities of the data storage system.

9. The method of claim 1 , wherein scaling the number of virtualization resource units allocated to the first application comprises:

determining that a surplus of resources is available for the one or more applications;

selecting the first application from the one or more applications; and

scaling the first application based on whether the surplus of resources is sufficient to scale the first application based on the resource ratio associated with the first application.

10. The method of claim 1 , further comprising scaling the number of virtualization resource units allocated to the first application and one or more other applications including:

determining that a surplus of resources is available for the first application and the one or more other applications;

allocating the surplus of resources among the first application and the one or more other applications; and

scaling the first application and the one or more other applications based on the allocated surplus of resources.

11. The method of claim 1 , wherein scaling the number of virtualization resource units allocated to the first application comprises:

receiving a request to launch the first application of the one or more applications;

provisioning a first amount of resources for the first application; and

allocating a second amount of resources for the first application.

12. The method of claim 11 , wherein a scaled version of the first application is comprised of a plurality of additional virtualization resource units, wherein the plurality of additional virtualization resource units are hosted on a same storage node as the plurality of virtualization resource units of the first application.

13. The method of claim 11 , wherein a scaled version of the first application is comprised of a plurality of additional virtualization resource units, wherein the plurality of additional virtualization resource units are hosted on one or more different storage nodes than one or more storage nodes hosting the first application.

14. The method of claim 1 , wherein the data storage system is comprised of a plurality of storage nodes, wherein the first application of the one or more applications is comprised of a plurality of virtualization resource units.

15. The method of claim 14 , wherein the plurality of virtualization resource units are hosted across one or more of the plurality of storage nodes.

16. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

monitoring system resource utilizations by one or more core functionalities of a data storage system;

based at least in part on the monitored system resource utilizations, determining a system resource allocation for one or more applications of the data storage system, wherein the one or more applications includes a first application that is comprised of a plurality of layers, wherein each layer of the plurality of layers of the first application is comprised of one or more corresponding virtualization resource units, wherein the one or more corresponding virtualization resource units at each of the plurality of layers of the first application is expressed as a resource ratio; and

based at least in part on the determined system resource allocation, scaling a number of virtualization resource units allocated to the first application to maintain the resource ratio of the first application, wherein the number of virtualization resource units allocated to the first application is based on a multiple of the resource ratio of the first application, wherein scaling the number of virtualization resource units allocated to the first application comprises increasing or decreasing a total number of the one or more corresponding virtualization resource units associated with each of the plurality of layers of the first application to maintain the resource ratio of the first application.

17. The computer program product of claim 16 , wherein scaling the number of virtualization resource units allocated to the first application comprises:

receiving a request to launch the first application;

determining a priority associated with the first application; and

scaling the first application based on the determined priority.

18. The computer program product of claim 16 , wherein the virtualization resource units are virtual machines or virtualization containers.

19. A system, comprising:

a processor configured to:

monitor system resource utilizations by one or more core functionalities of a data storage system;

based at least in part on the monitored system resource utilizations, determine a system resource allocation for one or more applications of the data storage system, wherein the one or more applications includes a first application that is comprised of a plurality of layers, wherein each layer of the plurality of layers of the first application is comprised of one or more corresponding virtualization resource units, wherein the one or more corresponding virtualization resource units at each of the plurality of layers of the first application is expressed as a resource ratio; and

based at least in part on the determined system resource allocation, scale a number of virtualization resource units allocated to the first application to maintain the resource ratio of the first application, wherein the number of virtualization resource units allocated to the first application is based on a multiple of the resource ratio of the first application, wherein to scale the number of virtualization resource units allocated to the first application, the processor is configured to increase or decrease a total number of the one or more corresponding virtualization resource units associated with each of the plurality of layers of the first application to maintain the resource ratio of the first application; and
