Cluster
Noun · Development
Definitions
A group of machines or processes that work together as a coordinated unit to provide compute capacity, storage, scheduling, or fault tolerance. Clusters are common in orchestration platforms, databases, analytics systems, and high-availability services where one node alone is not enough.
In plain English: A group of machines or processes working together as one system.
Example: "The search cluster needed rebalancing because two nodes were holding most of the shards and becoming hotspots during traffic spikes."
