Airflow is a Python-based workflow orchestrator, also known as a workflow management system (WMS). According to Prefects docs, the server only stores workflow execution-related data and voluntary information provided by the user. Another challenge for many workflow applications is to run them in scheduled intervals. As you can see, most of them use DAGs as code so you can test locally , debug pipelines and test them properly before rolling new workflows to production. Benefits include reducing complexity by coordinating and consolidating disparate tools, improving mean time to resolution (MTTR) by centralizing the monitoring and logging of processes, and integrating new tools and technologies with a single orchestration platform.
