Description: A node manager is an essential component in container orchestration systems, such as Docker Swarm and Kubernetes. Its primary function is to manage the state and health of nodes within a cluster, ensuring that all containers run efficiently and that resources are distributed appropriately. This component monitors the performance of each node, detecting failures and making decisions about task rescheduling in case a node becomes inoperative. Additionally, the node manager is responsible for communication between nodes, facilitating coordination and load balancing. Its relevance lies in the ability to maintain high availability and resilience of the system, which is crucial in production environments where service continuity is fundamental. In summary, the node manager is a pillar in container orchestration architectures, allowing developers and system administrators to effectively manage their applications in distributed containers.
