DevOps Dictionary

Karpenter is an open source tool that automatically adjusts the number of nodes in a Kubernetes cluster based on workload demands. It helps keep clusters responsive to changes by adding nodes when more resources are needed and removing them when they are not, which reduces unnecessary costs and resource waste. Without Karpenter, clusters might run with too few or too many nodes, leading to slower performance and inefficient resource use, since node management would remain manual and less responsive.
