System and method for network traffic management and load balancing

Abstract

A method for providing load balancing and failover among a set of computing nodes running a network accessible computer service includes providing a computer service that is hosted at one or more servers comprised in a set of computing nodes and is accessible to clients via a first network. Providing a second network including a plurality of traffic processing nodes and load balancing means. The load balancing means is configured to provide load balancing among the set of computing nodes running the computer service. Providing means for redirecting network traffic comprising client requests to access the computer service from the first network to the second network.; Providing means for selecting a traffic processing node of the second network for receiving the redirected network traffic comprising the client requests to access the computer service and redirecting the network traffic to the traffic processing node via the means for redirecting network traffic. For every client request for access to the computer service, determining an optimal computing node among the set of computing nodes running the computer service by the traffic processing node via the load balancing means, and then routing the client request to the optimal computing node by the traffic processing node via the second network.
