From maintenance to innovation: Checking in on Checkout.com’s Cloud Composer 3 migration

Checkout.com migrated from self-managed Apache Airflow to Google Cloud's Managed Service for Apache Airflow (Gen 3), reducing operational friction, simplifying dependency management, and improving developer velocity. This resulted in improved reliability, cost efficiency, and scalability. The company offloaded infrastructure responsibility and took advantage of Google Cloud's managed scalability. The results were immediate and measurable across three areas: reliability, cost, and developer velocity. The migration allowed the team to focus on building pipelines instead of server management, patching, and incident response.
