应用的自动化部署是将现有应用向云平台平滑迁移的重要前提，已成为云平台能否成功实施的重要因素。文章从用户实际出发，基于VMware IaaS云平台设计并实现了面向SLA的自动化部署私有云平台。同时，为满足不同用户的特定需求，在平台中引入了服务等级协定（SLA：Service Level Agreement），允许用户自定义QoS需求来申请服务组合，并将多阶段决策算法用于虚拟机的放置策略当中，保证用户的服务水平。最后，通过实验验证了平台的可用性与虚拟机放置算法的有效性。

Application automatic deployment is an important prerequisite for migration existing application to cloud platform and has become an important factor. From the user’s actual needs,we designed and implemented for the automated deployment SLA private cloud platform based on the VMware IaaS cloud platform. Meanwhile ,to meet the specific needs of different users,the platform introduced service level agreements,allowed the user to customize the QoS requirement to apply for service composition. Multi-stage decision algorithm is used for virtual machine placement policy to maintain the service level. Finally,the experiment verifies the usability of the platform and the effectiveness of the virtual machine placement algorithm.
