Hybrid cloud is an emerging cloud deployment model that integrates public and private clouds. The key technology in building a hybrid cloud environment is the method of integration of different types of clouds. However, research on cloud integration technology and related solutions is lacking. Therefore, the adoption of hybrid cloud environment has been delayed. In this paper, we propose a hybrid CSB (cloud service broker) architecture, which supports hybrid cloud construction by extending the concept of CSB to solve this problem. This paper focuses on service recommendation and integration functions, which are the most important functions of hybrid CSB, and suggests a recommendation method considering user requirements and private cloud environments; further, it describes the process of integrating different types of clouds using an integration script. The recommendation and integration method proposed in this paper can be used as a base technology for building a user-centric hybrid cloud environment.
