英文摘要： Compared with the traditional applications, cloud applications usually have the characteristics such as high availability, reliability, maintainability, autonomy, and interoperability across clouds, and can be visited by multiple Internet access means as needed. The development, operating, and maintenance environments of cloud platform layers can provide more convenient services and facilities at a higher level of abstraction for developing, operating, and maintaining cloud applications, and the services and facilities provide scalable run-time resources as needed and offer support for the characteristics the of cloud applications such as availability and reliability. The characteristics of cloud applications and new types of cloud platforms bring new scientific problems for developing, operating, and maintaining cloud applications. To take the development, operation, and maintenance of cloud applications as the research object, in this grant proposal we plan to study the modeling and model transformation technologies from the aspects of theory and practice, closely together with new development of related disciplines. To be more specific, (1) we are going to put forward a modeling concept system and further study an extended modeling language in order to provide a theory and technology foundation for modeling
