SSL Connection Failover in Web Clusters and its Evaluation

Abstract

It is important for enterprises to continuously provide web service. Failover cluster is a popular technology to provide web service without interruption. Although we have many well-established methodologies of failover for Hyper Text Transfer Protocol (HTTP), they can’t be applied in case of cryptographic channel. Then, keeping an encryption session between clusters, we design to migrate the session from one to others. Moreover, we evaluate it from the viewpoint of performance.
