Abstract

A method for use in a datacenter for load balancing services. A native registry is operated to provide a naming service storing service access information for services active in a network. On a node, an instance of a service is provided, and the native registry is updated with access information for the service. The method includes providing a content switch with a node controller such as on a network device. The method includes obtaining, with the node controller, service configuration information for the service from the native registry that includes the service access information. The node controller activates the service on the network by configuring the content switch based on the obtained service configuration information. The method includes the service node publishing a service definition for the service that includes the service access information and other information such as a service name, an IP address, and a load balancing algorithm.

Claims

1. A method of providing services in a computer network, comprising:

providing a native registry in memory of the computer network, the native registry comprising a naming service, storing service access information for services available in the computer network;

on a node of the computer network, providing an instance of a service;

updating securely the native registry with a set of service access information for the service associated with the provided service instance;

providing a content switch in the computer network that is loaded with a node controller;

for the service, obtaining service configuration information from the native registry including at least a portion of the service access information; and

asynchronously operating the content switch node controller to activate the service on the computer network including configuring the content switch based on the obtained service configuration information.

2. The method of claim 1, prior to the updating of the native registry, operating the node of the computer network to publish a service instance definition on the computer network including the set of service access information.

3. The method of claim 2, wherein the service instance definition includes a service name and wherein the content switch node controller associates an IP address with the service based on the service name.

4. The method of claim 2, wherein the service instance definition is published to a virtual registry service of the computer network and a service instance associated with the service instance definition performs the updating using information available in the virtual registry service.

5. The method of claim 2, wherein the service definition comprises a load balancing algorithm for the service and wherein the content switch node controller activating the service further comprises creating a service group configuration including the service based on the load balancing algorithm.

6. The method of claim 2, wherein the service definition includes an IP address and a port for the service instance associated with the service.

7. The method of claim 1, wherein the content switch node controller listens on the computer network for service discovery updates indicating a new service being added to the native registry or a modification to a previously active service and, in response to one of the service discovery updates, accessing the native registry for service configuration information associated with a service name provided in the one of the service discovery updates.

8. The method of claim 7, further comprising repeating the providing an instance, the updating of the native registry, the obtaining service configuration information, and the operating of the content switch node controller steps for the new service being added to the computer network including synchronizing changes between a computer infrastructure and a switching or routing environment.

9. A computer system adapted for providing and managing services, comprising:

a native registry providing a naming service for services in the computer system;

a plurality of service instances provided on nodes of the computer system, wherein the service instances publish the services and the native registry stores service access information based on the publishing of the services including associate a subset of the service access information with a name associate with each of the services; and

a content switch with a node controller, the content switch node controller acting to access the native registry to obtain configuration information including the service access information for the published services, to configure a service access IP address, port, and protocol for each of the published services that is associated with the service name, and to activate the published services for access on the computer system.

10. The system of claim 9, wherein the content switch node controller listens for service discovery updates in the computer system and, in response, accesses the native registry for the configuration information and to update configuration of the content switch.

11. The system of claim 9, wherein the publishing of the services includes providing a service definition to the native registry that includes at least a service name and an IP address.

12. The system of claim 11, wherein the service definition further comprises a port, protocol, and naming information for the service instance on one of the nodes.

13. The system of claim 11, wherein the system further comprises a service registry storing service information for each of the services including a load balancing algorithm and health check information and wherein the content switch node controller accesses the service registry to obtain the stored service information and, in response, the content switch node controller to configure the content switch to control access to the services using the load balancing algorithms and the health check information.

14. The system of claim 9, wherein the publishing by the service instances includes providing a subset of a service definition to a virtual registry service of the computer system and wherein the native registry updates a set of service access information associated with each of the service instances by the service name based on the provided subset in the virtual registry service.

15. A load balancing method for services, comprising:

defining an IP address in a pool in a service registry;

installing a service instance on a node of a networked system;

from the service instance, publishing a service to a virtual service registry;

updating a native registry comprising a naming service with information for the service available via the virtual service registry; and

operating a content switch to activate the service based on the IP address and the information from the native registry.

16. The method of claim 15, wherein the content switch operates to create a service group configuration based on attributes retrieved from the native registry for the service.

17. The method of claim 15, wherein the IP address is pulled by the content switch from the service registry.

18. The method of claim 15, wherein the native registry is configured with a name for the service and wherein the content switch configures a service access IP address based on the IP address in the pool of the service registry and the service name from the native registry.

19. The method of claim 15, wherein the publishing of the service comprises advertising a subset of a service definition associated with the service instance and wherein the subset includes a service name and a load balancing algorithm for use by the content switch in providing the service.

20. The method of claim 19, wherein the subset further includes health checking information for the service and access information for the service instance.
