Research on SLA-based Business Automatic Deployment of Private Cloud Platform

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 (Service-Level Agreement) private cloud platform based on the VMware IaaS (Infrastructure as a Service) 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.
