Cloud computing stores data and program in the Internet of Things instead of computer hardware, allowing remote connection and information extraction. Transforming manual manufacturing system in the traditional manufacturing industry to a Cloud computing-enabled automation system will be an advantage in a sense that cloud manufacturing may connect the management to the plant site in the manufacturing industry. The manufacturing sector could utilize data that being generated from the automation system to resolve relevant issues such as assets feasibility, energy efficiency application, products traceability, flexible manufacturing and utilization, as well as environment and security management. Advanced corporate data analysis and Cloud related technologies will also facilitate the growth of Cloud applications. The transmission and connection integration technology shall be the critical development focus; the maturity of such technology will also affect its development timetable.
