论文摘要
在过去的几年中，边缘和云计算基础架构的扩散以及越来越多的移动设备促进了许多新型应用的出现。但是，这种复杂性的增加还为服务提供商带来了新的挑战，例如，在运行时相互依存的服务有效管理。一种策略是通过将服务迁移到合适的服务器来动态分配服务。但是，并非每个微服务都可以作为无状态实例部署，从而导致实时迁移技术的次优性能。在这项工作中，我们提出了一种新颖的实时迁移方案，重点是边缘和云环境中的状态微服务，通过利用基础消息传递基础结构来重建服务的状态。这种方法不仅可以在各种微服务部署方案中应用，而且实验评估结果还表明，与停留和拷贝迁移方法相比，停机时间减少了19.92％。
In the last few years, the proliferation of edge and cloud computing infrastructures as well as the increasing number of mobile devices has facilitated the emergence of many novel applications. However, that increase of complexities also creates novel challenges for service providers, for example, the efficient management of interdependent services during runtime. One strategy is to reallocate services dynamically by migrating them to suitable servers. However, not every microservice can be deployed as stateless instances, which leads to suboptimal performance of live migration techniques. In this work, we propose a novel live migration scheme focusing on stateful microservices in edge and cloud environments by utilizing the underlying messaging infrastructure to reconstruct the service's state. Not only can this approach be applied in various microservice deployment scenarios, experimental evaluation results also show a reduction of 19.92% downtime compared to the stop-and-copy migration method.
