Enterprises are interested in migrating systems to the cloud due to their scalability, flexibility and apparent cheapness. This paper investigates the benefits and significances of cloud migration in the intelligent environmental protection industry. In the case of the Chihu Lake industrial zone, we proposed and implemented an overall solution to solve the pain points, satisfy the demands and reduce the cost effectively. The implementation result indicates that it can noticeably improve the efficiency of environmental management and pollution control. In addition, the software developed by us not only can monitor the dynamic changes of the environment in real time, but also provide overt interfaces service and various portals for different roles. This work provides new wisdom for the application migration in other fields.
