云计算PaaS(platformasaservice,平台即服务)平台是互联网领域近几年来非常热的技术方向,不仅可以为用户提供开发环境、开发平台和硬件资源,还可以提高硬件资源的利用率,降低业务运营成本。然而,在提供服务的过程中,缺乏一种有效的机制来约束服务提供商的行为。文章为实现云计算PaaS平台下对应用的监测,提出了拓扑管理的概念。应用拓扑可以监测应用与资源的关系,资源拓扑可以监测资源与应用的关系,两者从不同的角度实现对应用的监测。文章采用哈希数组保存拓扑信息,采用消息总线的“发布-订阅”模式传递消息,实现拓扑信息的获取,将结果使用网页进行展示。本系统可以使服务提供商清晰地掌握系统中应用与资源的关系以及资源情况,有效提高资源利用率,因此,系统可以提升服务质量,进而保障用户利益。应用拓扑展示和资源拓扑展示可以及时反映系统中应用与资源的关系,从两种不同的角度展示出来,给云计算提供者管理应用提供了很大的方便。
雲計算PaaS(platformasaservice,平檯即服務)平檯是互聯網領域近幾年來非常熱的技術方嚮,不僅可以為用戶提供開髮環境、開髮平檯和硬件資源,還可以提高硬件資源的利用率,降低業務運營成本。然而,在提供服務的過程中,缺乏一種有效的機製來約束服務提供商的行為。文章為實現雲計算PaaS平檯下對應用的鑑測,提齣瞭拓撲管理的概唸。應用拓撲可以鑑測應用與資源的關繫,資源拓撲可以鑑測資源與應用的關繫,兩者從不同的角度實現對應用的鑑測。文章採用哈希數組保存拓撲信息,採用消息總線的“髮佈-訂閱”模式傳遞消息,實現拓撲信息的穫取,將結果使用網頁進行展示。本繫統可以使服務提供商清晰地掌握繫統中應用與資源的關繫以及資源情況,有效提高資源利用率,因此,繫統可以提升服務質量,進而保障用戶利益。應用拓撲展示和資源拓撲展示可以及時反映繫統中應用與資源的關繫,從兩種不同的角度展示齣來,給雲計算提供者管理應用提供瞭很大的方便。

Cloud computing PaaS (platform as a service) platform draws wide attentions in recent years. Not only does it provide environment and resources for users, it also improves the utilization of hardware resources and reduces business operation costs. However, there is lack of mechanism to constrain the behavior of providers. In order to ifll the gap, the concept of topology management was brought up. In one hand, the application topology can monitor the relationship between applications and resources, in another hand, resource topology can monitor the relationship between resources and applications, both of them can realize monitoring of applications from different angles. We use a hash array to store topology information, and the message bus publish-subscribe model to pass the messages. After that, we can achieve the topology information, and then demonstrate the results in Web pages. To sum up, the PaaS platform driven by Cloud Foundry designed and implemented in this paper runs well. It presents the resource pool information and the relationship between application and resources clearly. Thus, the system can improve the quality of services and protect the interests of users. Application topology display and resource topology display can duly relfect the relationship between resources and application of the system, both of them display from different angles can provides great convenience to the cloud provider to manage application.
