Description: A worker node is a machine in Kubernetes that runs applications and services. In the context of Kubernetes, worker nodes are typically virtual machines or physical servers used to run the containers that make up the applications deployed in a Kubernetes cluster. These nodes are responsible for carrying out processing and storage tasks, and they communicate with the Kubernetes control plane to receive instructions on how to manage the containers. Each worker node has a Kubernetes agent, known as kubelet, which manages the containers on that specific node. Additionally, nodes can be scaled up or down based on demand, allowing for efficient resource management. The flexibility and scalability of worker nodes are crucial for the performance and availability of cloud applications, enabling organizations to quickly adapt to changing market needs and optimize their operational costs.
