移动云，发展最快的云 目前，移动云的公有云IaaS+PaaS市场份额国内排名第七，增速全球第一。私有云份额位列第5、政务云已进入行业前3。目前移动云已经为百万企业客户提供服务，并拥有1200多家生态合作伙伴。移动云秉承“5G时代，你身边的智慧云”理念，以云原生开源技术及标准为基础，充分发挥自身产品与技术创新优势，联合产业生态，为客户提供全栈云原生产品家族，帮助客户应用敏捷、业务智能，安全可信，面向未来持续演进。 2022年，移动云计划打造一款多集群管理平台，用于对底层的多个超大规模集群提供一个运维、管理的入口。具体来说，当时主要面临两个问题： 1. 多集群检索 2. 兼容不同版本的Kubernetes 在考虑了多种不同的解决方案之后，移动云选择了Clusterpedia。“首先，clusterpedia使用简单并且稳定。”李莉说，“因为Clusterpedia是一个比较新的项目，我们一开始是抱着尝试的态度。但通过实践证明，Clusterpedia完全能够承担起生产的重任，它至今稳定的工作着。”另外，该团队表示，Clusterpedia内部对版本兼容处理非常严谨，客户端完全不用改代码，甚至不用升级client-go，这个特点帮助他们减少了很升级多成本。 “Clusterpedia改善了我们在多集群中查询的体验” — 李莉，云原生团队leader 在引入Clusterpedia之前，没有一个合适的多集群资源检索工具，随着业务的增长，数据中心的规模在不断的扩大，快速在多集群中检索到一个特定的资源是一个急需解决的问题。“我们需要在一个面板上能检索到所有K8s集群上的资源，”李莉说，“此前，我们要详细记录每个K8s集群上运行着哪些应用，然后再基于这个记录去对应的K8s集群上查找，而现在，我们可以基于Clusterpedia做到快速的多集群资源检索，极大地提升了多集群资源查找效率”。 “Clusterpedia同时也解放了我们的运维人员，它给我们的运维人员提供了一个统一的面板，让我们的运维人员在排查问题时不再为多集群之间的切换而烦恼。” 李莉说，“Clusterpedia节省了我们的运维人员至少50%的运维时间。” “同时，Clusterpedia除了为多集群提供了一个强有力的资源检索工具，它还提供了多集群资源的Watch功能。基于此，我们实现了对多集群资源状态事件的统一汇聚，从而实现了对多集群资源状态监控和处理。” “此外，我们基于Clusterpedia成功的对一些产品组件进行了多集群能力改造，我们使用client-go的informer监控Clusterpedia的APIServer从而感知任意集群工作负载的状态，并进行相应的事件处理” “用户希望能够不改动任何代码，像是在单集群那样使用多集群，他们使用client-go、kubectl与Kubernetes交互。”李莉说，“Clusterpedia与原生Kubernetes api完全兼容，我们对Clusterpedia进行了一些小的改造，让它能够承担起多集群APIServer的角色。” “Clusterpedia是一个优秀的开源项目，我们在享受它带来的便利的同时，也一直在思考能为社区做些什么。” — 李莉，云原生团队leader “Clusterpedia是我们在CNCF发现的宝藏，在对社区索取的同时，我们也积极的参与到了对社区的贡献当中，”李莉说，“上文中提到的多集群资源的Watch功能，就是基于我们的业务需求，设计、研发、并最终回馈给社区的。在今后的工作中，我们期待和Clusterpedia社区有更深入的合作。我们计划研究一套多集群解决方案，可以让应用像运行在单集群上一样运行在多集群上，除了对多集群资源的读操作外，还有对多集群资源的增删改，另外还会涉及到多集群资源调度，多集群网络，多集群监控等领域。我们期待和社区一起成长。”
