[Abstract]:Cloud computing strategy provides users with a unified and standardized way to complete cloud computing resource scheduling, cloud computing resource monitoring, cloud computing security and other operations. Cloud computing strategies are usually formulated by senior enterprise leaders, cloud computing system administrators, cloud computing experts, and other roles that master the details of cloud platform system services. Ordinary users need the help of these advanced roles to define and use cloud computing strategies. As a result, current cloud systems manage cloud computing services and resources through strategies that lack agility. In view of the above problems, this paper studies how ordinary users can define strategies more conveniently in cloud systems, and concludes that the biggest difficulty of user-defined cloud computing strategies is that users lack the knowledge of the underlying service details of cloud systems. In order to solve this problem, this paper abstracts the main services and resources in the infrastructure namely service cloud platform based on OpenStack platform into a data model that users can easily understand and describe, and proposes a policy definition method based on data model. In order to complete the research content, this paper first studies cloud computing and policy definition related technologies. OpenStack is the most popular open source cloud computing platform at present. This paper introduces the whole structure of OpenStack and the core services in OpenStack. Then, this paper will analyze the disadvantage of OpenStack policy service which is difficult for users to use in practical application, and put forward the concept of OpenStack data model in view of this problem. By studying the core services of OpenStack, this paper defines computing, network and storage resources as five basic OpenStack data models, and studies three kinds of data models: resource association, authentication association and security group association. In this paper, OpenStack data model is applied to policy service, and a test example shows that the policy definition method based on OpenStack data model is easier to understand and define. Finally, this paper designs and implements the OpenStack policy generation system, and applies the policy definition method based on the OpenStack data model to the actual scenario, which provides a more convenient way for the user-defined cloud computing policy.
