nowadays due to the high demand for cloud services a load balance mechanism for software defined networking (SDN) in a cloud environment appears to solve the availability and latency issues in the HTTP server. This paper presents a load balance mechanism that has been applied for a software defined networking (SDN) in a cloud environment for the HTTP server which received 6 million requests in total with 400 requests per time. The server will not respond to any further requests that have been transmitted from the client because it is overload. hence the solution is to apply a load balancing mechanism to measure the same parameters after applying load balance. In this scenario, HAproxy has been applied to the cloud environment and all of these 6 million requests with 4 connections per time have been received successfully, the HTTP server's traffic can be distributed among the pool of servers instead of one server this would. Eventually, The HAproxy is giving a good response time with no requests dropped after 6 million requests coming at the same time that help to enhance the availability and improve the latency of HTTP requests by having an HTTP load balancer.
