Cloud computing enables the evolution of modern software application design. Applications based on microservice architecture are an example. Meanwhile, multiclouds are widely accepted by enterprise as an infrastructure strategy; however, challenges remain. The autonomous and distributable nature of modern applications, as well as the complexity of multicloud infrastructure, often make universal application deployment management impractical. This phenomenon may further hinder application quality and efficiency. Therefore, deployment resource control and topology discovery in the multicloud infrastructure environment is an intriguing area of cloud computing research. This paper proposes a framework to manage application deployment in the multicloud environment. The framework uses a policy-based deployment control to automatically select and provide deployment resources from the multicloud infrastructure, and it subsequently uses topology discovery to visualize and verify the actual deployment. The proposed framework design is introduced in the paper, and a proof-of-concept prototype is implemented. Experiments in empirical scenarios are conducted. The experimental results indicate that the proposed framework is effective in controlling deployment resources and presenting actual deployment across clouds.

云计算使现代软件应用程序设计得以发展。基于微服务架构的应用程序就是一个例子。同时，多云已被企业广泛接受为基础架构策略。然而，挑战依然存在。现代应用程序的自治性和可分发性以及多云基础架构的复杂性，常常使通用应用程序部署管理变得不切实际。这种现象可能会进一步阻碍应用程序的质量和效率。因此，多云基础架构环境中的部署资源控制和拓扑发现是云计算研究的一个有趣的领域。本文提出了一个框架，用于管理多云环境中的应用程序部署。该框架使用基于策略的部署控制来自动从多云基础架构中选择并提供部署资源，并且随后使用拓扑发现来可视化并验证实际部署。本文介绍了提出的框架设计，并实现了概念验证原型。在经验场景中进行实验。实验结果表明，该框架在控制部署资源和呈现跨云实际部署方面是有效的。
