Abstract: In order to solve the problems of insufficient resource utilization, complex design of high availability architecture, and difficulty in horizontally expanding computing capacity in the Infrastructure as a Service (IaaS) mode, this paper used a domestic Linux operating system as the cloud foundation to build a privatized container cloud platform with multi tenant, high availability, and scalability characteristics. The platform greatly improved business availability and resource utilization, while also improved business availability and resource utilization by deploying through privatization, could achieve the maximum protection of enterprise network security and data privacy. The paper used the Kubernetes container orchestration tool to implement lightweight container deployment and management of information systems and applications, provided a technical practice path for the building of enterprise level data centers. At the same time, it provided a solution for minimizing resource consumption for enterprise stock information systems and application migration to the cloud.
