摘　　要：Kubernetes等云原生技术在业界应用时,承载能力有限,无法满足更高可用性要求,且易被云供应商锁定;东数西算等战略的实施运行,需以多集群管理技术为基础,但是传统的云管平台难以满足跨多云应用的服务部署和治理的挑战。提出软件定义的自组织基础设施管理、幂等的分层调度新理念,实现以集群为最小单位的弹性基础设施管理架构,将多个Kubernetes集群组成中心式、去中心式、树状等任意拓扑结构,进行应用的跨云调度及管理。方案基于树状集群结构进行了测试验证,并与其他方案对比,测试结果表明该方案能够满足未来分布式云场景下海量集群组织管理需求,且保持接入新集群不超过1 s,应用的调度延迟不超过200 ms。When cloud-native technologies such as Kubernetes are applied in the industry,their carrying capacity is limited,they cannot meet higher availability requirements,and are easily locked in by cloud providers.The implementation and operation of strategies such as Eastern Data and Western Computing need to be based on multi-cluster management technology.However,traditional cloud management platforms cannot meet the challenges of service deployment and governance across multi-cloud applications.Aiming at the above problems,this paper puts forward a new concept of software-defined self-organizing infrastructure management and idempotent hierarchical scheduling.An elastic infrastructure management architecture with clusters as the smallest unit is designed and implemented,which can make multiple Kubernetes clusters into a multi-cluster organization scheme with any topology structure such as central,decentralized and tree,and carry out cross-cloud scheduling and management of applications.The tree structure is tested and compared with other solutions,which can well meet the huge number clusters organization and management requirements in the future distributed cloud scenario while keep the registration latency of cluster limit to 1 s,scheduler latency limit to 200 ms.
