The invention discloses a PaaS cloud implementation method based on containers. The method comprises following steps: saving configuration information of all containers and providing disposition; a deployment strategy ensuring that multiple containers under the same APP are scattered across different hosts; performing management on the host and containers and one physical cluster being corresponding to multiple projects, etc.. Therefore, the introduction of containers into the cloud computing basic resource delivery to provide PaaS layer services is realized, reducing waste of resources caused by the traditional PaaS products using virtual machines, increasing disposition efficiency and reducing exploitation and test period for users; the method is a lightweight VM solution scheme based on process containers, realizing a resource isolation and quota of an application program grade; Compared with the traditional cloud infrastructure system implementation, the container-based cloud service system has lower cost of overall ownership, higher resource utilization and is more stable and reliable, which further enhances the virtualization efficiency, improves resource utilization, accelerates enterprise devops process, and provides fast and effective support services for applications.
