Inference performance bottlenecks on Lambda
WHAT IT TESTS: serverless ML serving limits. OUTLINE: cold starts loading the model, memory and CPU limits, no GPU, and package size dominate; mitigate with provisioned concurrency, loading the model once outside the handler, smaller models, and right-sized…
WHAT IT TESTS: whether you know serverless constraints for inference and how to mitigate them. ANSWER OUTLINE: bottlenecks include cold-start latency from initializing the runtime and loading a large model, constrained memory and CPU with no native GPU, deployment package and layer size limits, and per-invocation model loading. Mitigate with provisioned concurrency to keep instances warm, loading the model once in the init phase outside the handler, using smaller or quantized models, increasing memory to gain proportional CPU, and storing…
