Application Performance Monitoring: traces, logs, metrics in one platform
Datadog and New Relic dominate enterprise observability: real-time monitoring of application performance, infrastructure, and user experience across distributed systems. Career path: SRE L2 (dashboards, alerts, $130-170k) β L3 (cost optimization, custom metrics, $170-220k) over 2-3 months. Cost: $15-60/host + sampling strategies critical. Lives next to Prometheus, OpenTelemetry, Grafana Cloud, Honeycomb, Splunk.
Datadog and New Relic are commercial all-in-one observability platforms providing real-time application performance monitoring (APM), infrastructure monitoring, log aggregation, and distributed tracing in a single interface. Career progression: SRE L2 (dashboards, alerts, monitoring playbooks, $130-170k) β L3 (cost optimization, custom metrics, $170-220k) over 2-3 months. Cost is critical: both platforms charge per host/metric/GB of logs ingestedβbills can explode from $5k to $50k+/month without sampling strategies. Datadog dominates market share (25%+) with superior integrations (500+) and APM UI; New Relic offers simpler pricing and faster onboarding. In 2026, commercial APM tools are standard at companies >$50M revenue; startups often use open-source Prometheus/Grafana before graduating to paid platforms. Both platforms ingest the same open standards (OpenTelemetry, Prometheus formats), so skills transfer between them. The learning curve is shallow (2-3 months) because the UI is self-documenting; depth comes from understanding cost optimization and alert rule design.
