A 500ms latency spike in a distributed system could be a slow RDS query, a Lambda cold start, a downstream API timeout, or a CloudWatch Logs ingestion delay. Finding the cause requires correlated logs, traces, and metrics — not grep.

A technical deep dive into EC2 performance optimization for API workloads — covering instance family selection, Graviton vs x86 economics, network tuning, EBS configuration, and Linux kernel parameters that directly impact throughput and tail latency.
