Abstract: To enhance the flexibility and resource utilization of tourism retail platforms, shorten resource expansion/contraction time and fault recovery time, this paper designed a platform upgrade plan based on containerized technology. The paper implemented synchronous promotion of business and technology through the parallel strategy of research and development tasks, divided the giant stone application into multiple microservice applications and designed a containerized upgrade and deployment method that was compatible with multiple architectures, and implemented template-based deployment and gradual traffic switching through containerized deployment. Practice has proven that the platform upgrade plan has little impact on business research and development, supports rapid upgrades of hybrid architecture applications, and has the characteristics of low cost and smooth migration.
