Cloud Computing Transformation Considering Operational Efficiency

Companies that have their own IT center built and operated an on-premise system. But recently, cloud computing is considered to secure system reliability and reduce management costs. IT resources can be efficiently utilized and paid for. 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. 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, and security was also enhanced. Cloud computing is a service unit through which both operational efficiency and functionality can be satisfied.
