Abstract
Containerization technology, as a significant innovation in the field of cloud computing, provides applications with a consistent runtime environment through lightweight virtualization, demonstrating substantial advantages in improving resource utilization and simplifying application deployment and management. This paper aims to explore the current application status, challenges faced, and future development directions of containerization technology in cloud computing environments. Based on a systematic review of existing literature and technical analysis of mainstream container platforms such as Docker and Kubernetes, combined with practical application scenarios, this study delves into key technological aspects including container orchestration, network communication, and storage management. The research reveals that containerization technology significantly enhances the flexibility and scalability of cloud services but also presents challenges concerning security and stability. Particularly in multi-tenant environments, the effectiveness of container isolation mechanisms becomes an urgent issue to address. This paper proposes a multi-level security policy-based container isolation fr amework that effectively strengthens the isolation between containers; it also designs an adaptive traffic scheduling algorithm targeting container network performance optimization, achieving intelligent allocation of network resources. Research findings indicate that this fr amework and algorithm can substantially improve the overall performance and security of container platforms, providing theoretical basis and technical support for the widespread application of containerization technology in the cloud computing domain. Furthermore, this paper looks ahead to the future trends in container technology, emphasizing the importance of standardization, cross-platform compatibility, and intelligent operations and maintenance, offering reference directions for related research.
