Datadog

Datadog delivers a unified observability platform (SaaS) for cloud-scale applications, providing real-time monitoring and analytics across your entire technology stack.

Datadog is your single pane of glass for operational visibility: it aggregates metrics, traces, and logs from over 600 integrations (AWS, Kubernetes, etc.) into one platform. The core strength lies in unified monitoring, specifically Application Performance Monitoring (APM), Infrastructure Monitoring, and Log Management. You deploy the Datadog Agent to hosts, containers, and serverless environments, collecting high-resolution data in real-time. This allows teams to quickly correlate frontend user experience (RUM) with backend performance issues (APM), identifying bottlenecks and resolving incidents fast. The platform’s customizable dashboards and intelligent alerting ensure you shift from reactive firefighting to proactive system optimization.
