Companies built IT Center and operated an on-premise system because IT is a kind of asset. But the pace of change in management is accelerating and the pressure on cost efficiency in the IT sector is increasing. Cloud computing is considered to secure system reliability and reduce management costs. IT resources can be efficiently utilized and paid for used. Cloud computing for each service unit was considered as a way to meet an efficient utilization of IT resources without compromising existing system reliability when providing new services. Cloud system enables real-time orchestration, and has excellent security. As a hybrid method that implemented cloud computing while maintaining the existing infrastructure, it was possible to operate an uninterrupted system as a result of system construction Therefore, companies were deploying and migrating their intranet services to cloud servers. However, it is also true that cloud migration makes system complexity increase, and system reliability is compromised by the increase of management points especially securities. It is necessary to learn about practice-oriented cloud migration and how to maintain mixed security policies when maintaining on-premises systems is effective.
