Lab: ship a monitored deployment

Stand up two model-server replicas behind an nginx gateway with Prometheus and Grafana, load-test it, find the concurrency where your SLO breaks, kill a replica on purpose, and make an alert fire.

In this lab you build the whole operational loop from this course: replicas, a gateway, metrics, dashboards, a load test, an alert and deliberate failures. By the end you will have a number, "the concurrency at which p95 TTFT crosses our SLO", and evidence that a replica failure causes a blip, not an outage.

Time: about an hour. You need: Docker with Compose, and a model: either a GPU with a 7 to 8B GGUF, or a small 1 to 3B GGUF on CPU (slower, but all the signals still appear). Use the load tester from concurrency and load testing.
