Step-by-Step Guide to Becoming an SRE: LLM Monitoring and Canary Deploys
ashishllm · x · 2026-09-18
Replying to a PhonePe SRE's career post, the author lays out a step-by-step path into Site Reliability Engineering with an LLM-serving focus:
- What SREs do: keeping systems alive — deploying an LLM model is one thing; serving thousands of concurrent users without downtime is another.
- Key metrics for deployed LLMs: GPU utilization, per-component p95 latency, throughput, TTFT, inter-token latency, and end-to-end latency.
- Shipping new model versions: use canary deployments — route 5% of traffic first, watch the metrics, scale up if healthy, roll back if not.
A practical reference for engineers targeting the AI infra/SRE track.
