Monitor code deployments with Deployment Tracking in Datadog APM

Datadog's Deployment Tracking feature helps teams implement continuous integration and delivery pipelines by providing visibility into the performance of code deployments. It uses a unified `version` tag to aggregate data on infrastructure assets, traces, trace metrics, profiles, and logs, enabling developers to compare the performance of new code against existing live code. This allows for quick rollbacks in case of issues, ensuring minimal customer-facing impact. Deployment Tracking is integrated with Datadog's APM features, providing out-of-the-box graphs that visualize RED (requests, errors, and duration) metrics across versions, making it easier to spot problems before they become serious issues.
