active node

An active node is an operational node that actively participates in processing tasks, serving requests, and executing workloads within a distributed system.

Key characteristics include maintaining a healthy operational state (powered on and connected), processing workloads through computations or request handling, ensuring availability to handle incoming tasks, providing responsive performance, participating in cluster operations such as data replication, load balancing, and failover, and being continuously monitored for health and performance metrics.

Common use cases include high availability clusters where active nodes provide redundancy and resilience, load-balanced environments that distribute workload across nodes, distributed computing frameworks for parallel processing, fault-tolerant systems enabling seamless failover, and scalable architectures that dynamically adjust active nodes based on demand.
