Admission Control
A traffic control mechanism in distributed systems that evaluates current resource states and capacity before requests enter the backend processing system, deciding whether to accept new requests. The goal is to prevent system instability caused by overload and resource contention.
Timeline (last 90 days)
The team designed a Lambda dispatcher with admission control, responsible for enforcing the cluster concurrency limit.
Discrete event simulation showed that if a naive direct-dispatch approach were used, the system would lose 65% of jobs.
For scarce resources such as GPUs, proactive concurrency limits are more reliable than reactive retries.
