【Abstract】 This pares and analyses the technical characteristics and the solutions of the puting adopted in some current representative enterprises. It summaries that puting is puting platform that support for virtualization, dynamic-resource-pool and high availability, including the low-layer infrastructure and the application based on it. From this paper, readers prehend the current status and future trends of puting. Through the integration on both Eucalyptus system - an open-source puting platform - and Liferay system - an open-source content management system-, the detailed build process of the application-specific cloud platform is described, especially, creating the linux-based service-customized amazon machine image file (AMI) by the xen virtual tools in the virtualization-based
