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 admission-control layer built in this article consists of a local quota ledger and a four-leaf decision tree, and it runs before any request leaves the machine.
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.
