Build Node - CI/CD Glossary Definition
A build node is a single machine in a pool of runners that executes CI jobs.
A build node is one compute instance in a fleet of CI runners. Jobs are dispatched to available nodes; adding nodes increases how many jobs can run in parallel.
Scaling nodes
Throughput is bounded by the number of idle nodes. Autoscaling adds nodes when the build queue grows and removes them when it drains, trading responsiveness against cost.
