网络可扩展性和性能 阿里云目前在全球拥有 30 个数据中心和 89 个可用区，客户遍布全球。他们提供的 Kubernetes 托管服务（ACK）管理着数万个集群，其中最大的集群拥有超过 10,000 个节点。 在 Kubernetes 托管服务建立初期，阿里云使用 Flannel 作为网络组件。但随着平台的发展，他们意识到需要更复杂的解决方案来扩展平台并满足客户需求。 为应对这些挑战，他们开发了自己的 CNI 插件 Terway，以解决扩展难题。然而，使用 Terway 时，pod 网络流量仍需经过主机网络协议栈，随着集群规模扩大，这带来了更多的延迟。为解决延迟问题，他们转向 IPVLAN，使流量从 pod 端口直接进入 VPC，跳过主机网络协议栈。但这种方法并不适合 Kubernetes 服务，因为容器流量不再经过主机，无法被 kube-proxy 的规则转发。他们意识到，需要另一种解决方案来处理服务之间的流量。 “我们最初使用并修改了 Flannel，以通过 VPC 路由而不使用 overlay 网络。然而，这种做法带来了一些缺点：网络仍然不在同一层面，Flannel 还在集群中提供了第二个 CIDR…
