This paper describes the deployment of the IBM WebSphere Application Server (WAS) software in a set of virtual machines on VMware ESX at the Ohio Mutual Insurance Group (OMIG). This deployment has been in place for more than two years and it serves the needs of 200 users within the larger company and 2400 outside users among its affiliates outside the company. The performance of the virtualized WebSphere-based systems is seen to be very satisfactory for their users. The response times for the applications on the virtualized systems are better than those previously seen in the purely physical implementation.
