Abstract

The present disclosure is directed towards systems and methods of service chain load balancing. A controller intermediary to a client and computing infrastructure identifies a plurality of service chains. Each of the plurality of service chains include a path having an instance of a first service provided by the computing infrastructure and an instance of a second service provided by the computing infrastructure. The controller determines a path weight for each of the plurality of service chains. The path weight indicates a level of efficiency of delivering services in accordance with the service chain. The controller selects, based on a load balancing function and the path weight for each of the plurality of service chains, a service chain from the plurality of service chains to direct network traffic from a client.

Claims20

Dependent claims

A method, comprising:

receiving, by a device from a remote computing environment providing a plurality of services, information on a plurality of service chains responsive to a query by the device to the remote computing environment, wherein each of the plurality of service chains identifies a path at least between an instance of a first service of the remote computing environment and an instance of a second service of the remote computing environment;
identifying, by the device, for each of the plurality of service chains an efficiency level of a service chain for accessing at least the first service and the second service;
receiving, by the device, a request from a client of the plurality of clients to access one or more services of the plurality of services of the remote computing environment;
selecting, by the device, a service chain of the plurality of chains based at least on the efficiency level of each of the plurality of service chains;
and
communicating, by the device, the request via the selected service chain of the remote computing environment.

3 more elements

A system, comprising:

a device comprising one or more processors coupled to memory and configured to:
receive, from a remote computing environment providing a plurality of services, information on a plurality of service chains responsive to a query by the device to the remote computing environment, wherein each of the plurality of service chains identifies a path at least between an instance of a first service of the remote computing environment and an instance of second service of the remote computing environment;
identify for each of the plurality of service chains an efficiency level in using a service chain for accessing at least the first service and the second service;
receive a request from a client of the plurality of clients to access one or more services of the plurality of services of the cloud computing environment;
select a service chain of the plurality of chains based at least on the efficiency level of each of the plurality of service chains;
and
communicate the request to the selected service chain of the remote computing environment.
