Minimum cluster configurations
This topic describes minimum cluster configurations for Apigee hybrid. These minimum configurations apply to all of the supportedKubernetes platforms.
About node pools
A node pool is a group of nodes within a cluster that all have the same configuration. By default, hybrid assigns all pods to the default node pool; however, you can create dedicated node pools and assign hybrid components to them as a way of distributing resources.
Typically, you define dedicated node pools when you have pods with differing resource requirements. For example, theapigee-cassandra pods require persistent storage, while the other Apigee hybrid pods do not. For this reason, we recommend that you create a stateful node pool for Cassandra and a stateless node pool for the rest of the hybrid runtime services. SeeConfigure dedicated node pools for details.
The following section lists configurations for both stateful and stateless node pools.
Minimum configurations
Use these minimum configurations when setting up your cluster:
| Configuration | Stateful node pool | Stateless node pool |
|---|---|---|
| Number of nodes | 3 (per region) | 3 (per region) |
| CPU | 4 | 4 |
| RAM | 15 | 15 |
| Default label name | apigee-data | apigee-runtime |
| Storage | dynamic | Managed with theApigeeDeployment CRD |
Scaling the configuration
If you need to scale your initial configuration based on additional capacity or throughput needs, see the following topics:
- Configuring Cassandra for production
- Scaling Cassandra pods
- Configuring dedicated node pools
- Scale and autoscale runtime services
