This topic describes minimum cluster configurations for
Apigee hybrid. These minimum configurations apply to all of the supported
Kubernetes 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, the apigee-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. See Configure dedicated node pools for
details.
The following section lists configurations for both stateful and stateless node pools.
Minimum configurations
