Node Pools

Node Pool Overview

A node pool consists of one or more nodes with identical configurations within a cluster. Node pools have the following advantages:

• Resource isolation: Different types of workloads can be assigned to separate node pools to keep resources isolated. For example, CPU-intensive workloads and I/O-intensive workloads can be placed in distinct pools to optimize performance.
• Flexibility: Node pools can be configured and managed based on application needs. For example, if certain applications require GPUs, a dedicated GPU node pool can be created to meet those specific requirements.
• Scalability: Node pools can be independently scaled to accommodate workload fluctuations. For example, during peak hours, nodes can be added to specific pools.
• Fault isolation: If a node pool experiences failures, the impact is contained within that pool, minimizing disruptions to the rest of the cluster.
