Abstract

Systems, methods, and software described herein facilitate the management of virtual clusters in a large-scale processing environment. In one implementation, a method of operating a control node includes receiving a request to configure a virtual cluster with one or more data processing nodes, and identifying a tenant associated with the request. The method further provides identifying a namespace for the tenant, and identifying internet protocol (IP) addresses for the one or more data processing nodes. The method also includes generating namespace to IP address pairs for the one or more data processing nodes based on the namespace and the IP addresses, and configuring a domain name system (DNS) for the virtual cluster with the namespace to IP address pairs.

First claim

What is claimed is:

1. A method to operate a control node of a large-scale processing environment, the method comprising:
identifying a first tenant associated with a first request to configure a virtual cluster with one or more data processing nodes, wherein the first tenant represents an organization that shares the physical resources of the large-scale processing environment;
identifying a namespace for the first tenant;
identifying internet protocol (IP) addresses for the one or more data processing nodes;
generating namespace to IP address pairs for the one or more data processing nodes based on the namespace and the IP addresses;
configuring a domain name system (DNS) for the virtual cluster with the namespace to IP address pairs, wherein the DNS is associated with the first tenant.

2. The method of claim 1 wherein the one or more data processing nodes comprise one or more virtual machines or one or more containers.

3. The method of claim 1 further comprising:
identifying a second request to remove a data processing node from the virtual cluster;
identifying a namespace to IP address pair for the data processing node; and
removing the namespace to IP address pair for the data processing node from the DNS for the virtual cluster.

4. The method of claim 1 wherein the request to configure the virtual cluster with the one or more data processing nodes comprises an expand request to add the one or more data processing nodes to a preexisting virtual cluster, and wherein configuring the DNS for the virtual cluster with the namespace to IP address pairs comprises adding the namespace to IP address pairs to a preexisting DNS.

5. The method of claim 1 wherein the request to configure the virtual cluster with the one or more data processing nodes comprises a new cluster request to configure a new virtual cluster with the one or more data processing nodes.

6. The method of claim 1 further comprising initiating the one or more data processing nodes on at least one host computing system in the large-scale processing environment.

7. The method of claim 1 further comprising configuring the one or more data processing nodes with an IP address for the DNS.

8. The method of claim 1 further comprising:
receiving a second request to configure a second virtual cluster with at least one data processing node;
identifying a second tenant associated with the second request;
identifying a second namespace for the second tenant;
identifying secondary IP addresses for the at least one data processing node;
generating second namespace to IP address pairs for the at least one data processing node based on the second namespace and the secondary IP addresses; and
configuring a second DNS for the second virtual cluster with the second namespace to IP address pairs.

9. The method of claim 1 wherein identifying the IP addresses for the one or more data processing nodes comprises identifying, from a set of available IP addresses allocated to the large-scale processing environment, available IP addresses for the one or more data processing nodes.

10. An apparatus to manage a large-scale processing environment, the apparatus comprising:
one or more computer readable media;
a processing system operatively coupled to the one or more computer readable media; and
program instructions stored on the one or more computer readable media, that when executed by the processing system, direct the processing system to:
identify a first tenant associated with a first request to configure a virtual cluster with one or more data processing nodes, wherein the first tenant represents an organization that shares the physical resources of the large-scale processing environment;
identify a namespace for the first tenant;
identify internet protocol (IP) addresses for the one or more data processing nodes;
generate namespace to IP address pairs for the one or more data processing nodes based on the namespace and the IP addresses; and
configure a domain name system (DNS) for the virtual cluster with the namespace to IP address pairs, wherein the DNS is associated with the first tenant.

11. The apparatus of claim 10 wherein the one or more data processing nodes comprise one or more containers.

12. The apparatus of claim 10 wherein the processing instructions further direct the processing system to:
identify a second request to remove a data processing node from the virtual cluster;
identify a namespace to IP address pair for the data processing node; and
remove the namespace to IP address pair for the data processing node from the DNS for the virtual cluster.

13. The apparatus of claim 10 wherein the request to configure the virtual cluster with the one or more data processing nodes comprises an expand request to add the one or more data processing nodes to a preexisting virtual cluster, and wherein to configure the DNS for the virtual cluster with the namespace to IP address pairs, the program instructions direct the processing system to add the namespace to IP address pairs to a preexisting DNS.

14. The apparatus of claim 10 wherein the request to configure the virtual cluster with the one or more data processing nodes comprises a new cluster request to configure a new virtual cluster with the one or more data processing nodes.

15. The apparatus of claim 10 wherein the program instructions further direct the processing system to initiate the one or more data processing nodes on at least one host computing system in the large-scale processing environment.

16. The apparatus of claim 10 wherein the program instructions further direct the processing system to configure the one or more data processing nodes with an IP address for the DNS.

17. The apparatus of claim 10 wherein the program instructions further direct the processing system to:
receive a second request to configure a second virtual cluster with at least one data processing node;
identify a second tenant associated with the second request;
identify a second namespace for the second tenant;
identify secondary IP addresses for the at least one data processing node;
generate second namespace to IP address pairs for the at least one data processing node based on the second namespace and the secondary IP addresses; and
configure a second DNS for the second virtual cluster with the second namespace to IP address pairs.

18. The apparatus of claim 10 wherein, to identify the IP addresses for the one or more data processing nodes, the program instructions direct the processing system to identify, from a set of available IP addresses allocated to the large-scale processing environment, available IP addresses for the one or more data processing nodes.

19. A system for managing virtual clusters in a large-scale processing environment, the system comprising:
one or more host computing systems;
a control node configured to:
identify a tenant associated with a request to configure a virtual cluster with one or more data processing nodes, wherein the tenant represents an organization that shares the physical resources of the large-scale processing environment;
identify a namespace for the tenant;
identify internet protocol (IP) addresses for the one or more data processing nodes;
generate namespace to IP address pairs for the one or more data processing nodes based on the namespace and the IP addresses; and
configuring a domain name system (DNS) for the virtual cluster with the namespace to IP address pairs, wherein the DNS is associated with the first tenant.
