Cloud computing data centre: SDN controller network balancing load method

Abstract

A load balancing strategy for software defined networking (SDN) in the cloud seems to resolve the availability and latency difficulties in the HTTP server nowadays, thanks to the strong demand for cloud services. In this article, we show how to implement a load balancing system for software defined networking (SDN) in the cloud. The HTTP server handled 6 million requests, with 400 requests per second. Due to overload, the website's server will not reply to any more requests sent by the client. hence, after applying load balance, the same parameters may be measured using a load balancing system. The 6 million requests, each involving four connections, were all successfully accepted by the cloud environment's HA proxy, allowing the traffic from the HTTP server to be dispersed across a pool of servers rather than a single server. Having an HTTP load balancer helps to improve the availability and latency of HTTP requests, and the HA proxy eventually gives an adequate answer time with no requests lost, even after 6 million requests arriving at the same time.
