For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\n\nThis topic describes minimum cluster configurations for\nApigee hybrid. These minimum configurations apply to all of the supported\n[Kubernetes platforms](/apigee/docs/hybrid/supported-platforms).\n\nAbout node pools\n----------------\n\n\nA node pool is a group of nodes within a cluster that all have the same configuration. 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)"]]
