Analysis of Load-Balancing of Web Cluster Based on TLS Session Sharing

TLS (Transport Layer Security) is one of the most popular protocols to provide a secure channel between the client and Web server; however, the high overhead of which degrades the server performance considerably. Existing load-balancing schemes for TLS Web system can improve the performance of the system, but the balance of loads is very difficult for the features of TLS, which results in degrading total system's performance caused by existing load-balancing schemes for TLS Web system. In this paper, TLS Handshake and Session Resumption will run at the whole cluster. TLS session was broadcasted to all of the servers in the cluster when it is generated in a server and which will be reused in all servers. Finally, a new load-balancing cluster is proposed to share TLS session in cluster, and which can effectively improve the performance of TLS web cluster.
