Datadog provides cloud-based monitoring and observability software that lets engineering teams track the performance, uptime and security of the applications and infrastructure they run, particularly for companies operating in the cloud rather than their own data centers. Its platform pulls together metrics, logs and traces from many different parts of a customer's technology stack into one place, replacing a patchwork of separate monitoring tools that engineering teams previously had to juggle. Datadog sells primarily through a usage-based pricing model that scales with how much infrastructure and data volume a customer is monitoring, so its revenue grows as customers expand their cloud footprint. The company competes with a mix of specialized monitoring startups and the native monitoring tools built into major cloud platforms like AWS, Azure and Google Cloud.
