Application Updating Method for Legacy Server in Virtual Environment

Abstract

Dedicated hardware and cluster configuration tend to be applied to legacy servers built for infrastructure systems (ex. call control server) to reduce the failure rate. The transition of legacy servers to a virtual environment with common hardware like general information services is being considered, due to the advancement of virtualization and improved performance of common hardware. In conjunction with this, a suitable method is needed for updating applications of servers. This letter suggests methods for updating applications of legacy servers built in a virtual environment.
