摘要：Cloud computing has become a popular topic in many areas. It can publish various resources offered by a number of vendors as services. However, there is no valid technology to manage the resources or services. In this paper, the relations among the resources are classified into four classes: the relations among the resources having the same character, the relations among the variable part and invariable part of a service, the relations among the resources having the same interaction manner, and the relations among the resources that are incompatible but have to interoperate. Then four patterns are proposed to manage the resources in cloud. The motivation, condition, structure, generation and consequence are presented for each pattern. They can be used to improve the availability, scalability and reusability of the resources provided.
