Inference Server
System Analysis
Normal Behavior
Client applications dispatch prediction requests over gRPC or HTTP. The inference server queues requests within a microsecond window to form dynamic batches, forwards them to model instances allocated on CPU or GPU accelerators, executes tensor operations, and returns predictions.
Failure Behavior
If GPU memory runs out (OOM), batch queue timeouts expire, or host accelerator drivers desynchronize, the inference server drops prediction requests, enters crash loops, or fails Kubernetes readiness probes, interrupting live application predictions.

Why use a dedicated inference server instead of a standard Flask or FastAPI wrapper?
A dedicated inference server (such as Triton or vLLM) implements dynamic batching, C++ tensor scheduling, and GPU memory management. A simple Python web wrapper processes requests sequentially or suffers from Python GIL contention, resulting in 5x-20x lower throughput and vulnerability to CUDA OOM crashes under load.
What is dynamic batching in model serving?
Dynamic batching groups multiple independent client requests arriving within a configured latency threshold (e.g. 5ms) into a single batch for tensor execution. This amortizes GPU memory transfer overhead and drastically multiplies server throughput without noticeable client latency.
