Cloudcraft is a real-time cloud infrastructure modeling solution that enables users to visualize their cloud infrastructures and create dynamic architecture models. It provides insights into configurations, cost, and inter-service interactions. The tool automatically updates diagrams when the infrastructure changes. Datadog has recently acquired Cloudcraft, aiming to integrate its real-time observability data with Cloudcraft's capabilities to provide robust, dynamic architecture diagrams for customers. This integration will support cloud migrations, container adoptions, and other architectural changes.
