Emerging cloud-centric networks span from edge clouds to large-scale datacenters with shared infrastructure among multiple tenants and applications with high availability, isolation, fault tolerance, security, and energy efficiency demands. Live migration (LiMi) plays an increasingly critical role in these environments by enabling seamless application mobility covering the edge-to-cloud continuum and maintaining these requirements. This survey presents a comprehensive survey of recent advancements that democratize LiMi, making it more applicable to a broader range of scenarios and network environments both for virtual machines (VMs) and containers, and analyzes LiMi’s technical underpinnings and optimization techniques. It also delves into the issue of connections handover, presenting a taxonomy to categorize methods of traffic redirection synthesized from the existing literature. Finally, it identifies technical challenges and paves the way for future research directions in this key technology.

实现容器实时迁移的大众化，增强未来网络 - 一项调查


新兴的以云为中心的网络涵盖从边缘云到大型数据中心，在多个租户和应用程序之间共享基础设施，具有高可用性、隔离性、容错性、安全性和能效要求。实时迁移 （LiMi） 通过实现涵盖边缘到云连续体的无缝应用程序移动性并维护这些要求，在这些环境中发挥着越来越重要的作用。本调查全面调查了 LiMi 的最新进展，这些进展使 LiMi 大众化，使其更适用于更广泛的场景和网络环境，包括虚拟机 （VM） 和容器，并分析了 LiMi 的技术基础和优化技术。它还深入探讨了连接切换问题，提出了一个分类法，用于对从现有文献中合成的流量重定向方法进行分类。最后，它确定了技术挑战，并为该关键技术的未来研究方向铺平了道路。
