using Flannel but decided to move to Cilium in late 2018 for a couple of reasons: o support for NetworkPolicies ☐ feature-rich CNI implementation ☐ actively maintained project o healthy, supportive community experience overall ☐ reasonably easy to maintain ~3.5% of DOKS clusters are using {Cilium}NetworkPolicies directly ## • Upgrades have been pretty smooth ☐ moved from Cilium 1.4 initially to 1.8 today

Application-to-Application dependencies ☐ Controllers watch K8s clusters and translate policies into K8s NetworkPolicies to be enforced in the clusters ☐ There are also other enforcers to enforce L4 policies on -

Service Mesh 自动在 Service Mesh control plane 和应用程序命名空间中创建和管理多个 NetworkPolicies 资源。这是为了确保应用程序和 control plane 可以相互通信。 如果要禁用自动创建和管理 NetworkPolicies 资源，例如为了强制执行公司安全策略，您可以编辑 ServiceMeshControlPlane，将 spec.security 单租赁部署模型 在 Istio 中，租户是为一组部署的工作负载共享共同访问权限和特权的用户组。您可以使用租户在不同的团队之间提供一定程度的隔离。您可以使用 istio.io 或服务资源的 NetworkPolicies、AuthorizationPolicies 和 exportTo 注解来隔离对不同租户的访问。 从 Red Hat OpenShift Service Mesh 版本 1.0 开始，单租户、集群范围的 14.6. 了解网络策略 Red Hat OpenShift Service Mesh 自动在 Service Mesh control plane 和应用程序命名空间中创建和管理多个 NetworkPolicies 资源。这是为了确保应用程序和 control plane 可以相互通信。 例如，如果您已将 OpenShift Container Platform 集群配置为使用 SDN 插件，Red
