What CircleCI is
CircleCI runs build, test and deployment pipelines defined in a YAML file in your repository. It is a focused CI product rather than part of a wider suite, and it shows in configuration flexibility and speed.

By centralizing all your metrics into one platform, Datadog allows teams to detect performance issues, troubleshoot outages, and optimize their systems in real-time. It is the premier choice for organizations running complex, microservices-based architectures in the cloud.
