By exposing app‑specific signals, queue depth, batch latency, WebSocket count, as Prometheus metrics, a custom exporter lets the HorizontalPodAutoscaler react to real workload conditions instead of just CPU or memory. The guide walks through writing the exporter in Go, containerizing it, and wiring it into a cluster for reliable autoscaling.
Job queues do more than throttle throughput, they decide what to do when a scheduled run is still active. Choices like spawning a parallel copy, cancelling the old run, queuing the new task, or dropping it outright each carry subtle reliability risks. Understanding these trade‑offs prevents hidden failures in CI pipelines and data‑processing workloads.
Netflix engineered a streaming‑first topology service that ingests millions of network flow records per second across regions, delivering sub‑second query responses and fresh dependency views. The design tackles hot‑node hotspots, cross‑region aggregation, and memory pressure, showing how real‑time observability can survive at massive scale.
Red Hat shows how to replace costly frontier LLMs with on‑prem open‑source models for incident‑response automation, keeping logs and topology inside the data center. Their agentic AIOps design trims ticket triage from up to 90 minutes per incident to minutes, cutting compliance risk for regulated enterprises.
