Abstract

A method for managing service resources of a group of host machines is provided. Each host machine provides services for a corresponding set of data compute nodes (DCNs). The method receives service distribution configuration for a set of entities comprising at least one of a tenant, a service, and a provider. The method identifies a set of host machines on which a set of DCNs for the set of entities operate. The method determines an amount of resources to be assigned to each entity of the set of entities. The method communicates with the set of host machines to modify a set of resource pools available on each host machine.

Claims

1. A method for managing resources consumed by service machines executing on host computers, the method comprising:

receiving a service distribution configuration for a set of service machines executing on a set of host computers to perform a service for data messages associated with a first set of data compute nodes (DCNs) of a first tenant and for data messages associated with a second set of DCNs of a second tenant, the service distribution configuration specifying data regarding an allocation of at least one resource on the set of host computers that should be available to the set of service machines for the data messages of the first set of DCNs of the first tenant;

identifying the set of host computers on which the set of service machines execute to provide the service for the data messages of the first set of DCNs;

identifying an allocation of an amount of said resource for use by the identified set of service machines to process data messages of the first set of DCNs; and

communicating said identified allocated amount of the resource with the identified set of host computers to ensure that the set of service machines do not consume more than the allocated amount of the resource for the data messages of the first set of DCNs.

2. The method of claim 1, wherein the plurality of host computers operates in a datacenter, wherein the service distribution configuration identifies a distribution for resources between a plurality of different tenants of the datacenter.

3. The method of claim 1, wherein the service distribution configuration identifies a distribution for resources between different service providers operating on the plurality of host computers.

4. The method of claim 1, wherein the service distribution configuration identifies a distribution for resources between a set of host services and a set of third party services.

5. The method of claim 4, wherein the third party services operate as security DCNs on the host computers.

6. The method of claim 1, wherein identifying an allocation of an amount of resources to be assigned comprises proportionally determining the amount for each host computer in the set of host computers based on a number of DCNs operating on the host computer for each tenant with DCNs operating on the host computer.

7. The method of claim 1, wherein identifying an allocation of an amount of resources to be assigned comprises determining the amount for each host computer in the set of host computers based on a weight value assigned to each tenant with DCNs operating on the host computer.

8. The method of claim 1, wherein identifying an allocation of an amount of resources to be assigned comprises assigning, for each host computer in the set of host computers, a minimum amount of resources for each of a subset of the set of tenants with DCNs operating on the host computer, and distributing the remaining resources across the DCNs of remaining tenants with DCNs operating on the host computer.

9. The method of claim 1, wherein the allocated resource comprises a memory resource of a host computer.

10. The method of claim 1, wherein the allocated resource comprises a processing resource of a host computer.

11. A non-transitory machine readable medium storing a program which when executed by a set of processing units manages resources consumed by service machines executing on host computers, the program comprising sets of instructions for:

receiving a service distribution configuration for a set of service machines executing on a set of host computers to perform a service for data messages associated with a first set of data compute nodes (DCNs) of a first tenant and for data messages associated with a second set of DCNs of a second tenant, the service distribution configuration specifying data regarding an allocation of at least one resource on the set of host computers that should be available to the set of service machines for the data messages of the first set of DCNs of the first tenant;

identifying the set of host computers on which the set of service machines execute to provide the service for the data messages of the first set of DCNs;

identifying an allocation of an amount of said resource for use by the identified set of service machines to process data messages of the first set of DCNs; and

communicating said identified allocated amount of the resource with the identified set of host computers to ensure that the set of service machines do not consume more than the allocated amount of the resource for the data messages of the first set of DCNs.

12. The non-transitory machine readable medium of claim 11, wherein the plurality of host computers operates in a datacenter, wherein the service distribution configuration identifies a distribution for resources between a plurality of different tenants of the datacenter.

13. The non-transitory machine readable medium of claim 11, wherein the service distribution configuration identifies a distribution for resources between different service providers operating on the plurality of host computers.

14. The non-transitory machine readable medium of claim 11, wherein the service distribution configuration identifies a distribution for resources between a set of host services and a set of third party services.

15. The non-transitory machine readable medium of claim 14, wherein the third party services operate as security DCNs on the host computers.

16. The non-transitory machine readable medium of claim 11, wherein the set of instructions for identifying an allocation of an amount of resources to be assigned comprises a set of instructions for proportionally determining the amount for each host computer in the set of host computers based on a number of DCNs operating on the host computer for each tenant with DCNs operating on the host computer.

17. The non-transitory machine readable medium of claim 11, wherein the set of instructions for identifying an allocation of an amount of resources to be assigned comprises a set of instructions for determining the amount for each host computer in the set of host computers based on a weight value assigned to each tenant with DCNs operating on the host computer.

18. The non-transitory machine readable medium of claim 11, wherein the set of instructions for identifying an allocation of an amount of resources to be assigned comprises sets of instructions for:

assigning, for each host computer in the set of host computers, a minimum amount of resources for each of a subset of the set of tenants with DCNs operating on the host computer; and

distributing the remaining resources across the DCNs of remaining tenants with DCNs operating on the host computer.

19. The non-transitory machine readable medium of claim 11, wherein the allocated resource comprises a memory resource of a host computer.

20. The non-transitory machine readable medium of claim 11, wherein the allocated resource comprises a processing resource of a host computer.
