节点池是集群中全都具有相同配置的一组节点。默认情况下，Hybrid 会将所有 pod 都分配给默认节点池；不过，您可以创建专用节点池，并采用分配资源的方式为其分配 Hybrid 组件。
通常，如果 pod 具有不同的资源要求，您可以定义专用节点池。例如，apigee-cassandra pod 需要永久性存储空间，而其他 Apigee Hybrid pod 则不需要。因此，我们建议您为 Cassandra 创建有状态节点池，为其余的 Hybrid 运行时服务创建无状态节点池。如需了解详情，请参阅配置专用节点池。

By\ndefault, hybrid assigns all pods to the default node pool; however, you can create dedicated\nnode pools and assign hybrid components to them as a way of distributing resources.\n\n\nTypically, you define dedicated node pools when you have pods with differing resource\nrequirements. For example, the `apigee-cassandra` pods require persistent storage, while\nthe other Apigee hybrid pods do not. For this reason, we recommend that you create\na stateful node pool for Cassandra and a stateless node pool for the rest of the hybrid\nruntime services. See [Configure dedicated node pools](/apigee/docs/hybrid/v1.5/configure-dedicated-nodes) for\ndetails.\n\n\nThe following section lists configurations for both stateful and stateless node pools.\n\nMinimum configurations\n----------------------\n\n\nUse these minimum configurations when setting up your cluster:\n\n| **Note:** For **production** environments, we recommend a minimum of two clusters.\n\nScaling the configuration\n-------------------------\n\n\nIf you need to scale your initial configuration based on additional capacity or throughput needs,\nsee the following topics:\n\n- [Configuring Cassandra for production](/apigee/docs/hybrid/v1.5/cassandra-production)\n- [Scaling Cassandra pods](/apigee/docs/hybrid/v1.5/cassandra-scaling)\n- [Configuring dedicated node pools](/apigee/docs/hybrid/v1.5/configure-dedicated-nodes)\n- [Scale and autoscale runtime services](/apigee/docs/hybrid/v1.5/scale-and-autoscale)"]]
