                Machine Learning workflows
                in Apache Airflow

                Digital workflow management is growing in importance

                Today's day-to-day business activities are fully intertwined with digital processes. The number of those digital processes and their implementation as workflows is increasing rapidly, not least because of the growing importance of machine learning applications. Nowadays, analyses and forecasts are only started manually in the prototype state; a productive system relies on automation. Here, the choice of the workflow management platform is a key factor for long-term success.

                The challenge is that these digital processes must be centrally managed and organized. Especially for business-critical processes, reliable execution and flexibility in the workflow design are essential. In addition to pure execution, great importance is also attached to the monitoring and optimization of workflows and error management. Ideally, the processes are also designed in such a way that they can be easily scaled up. 

                Only if both the technical and professional side of the users is involved, acceptance and a sustainable integration of digital processes into the daily work routine can be achieved. The execution as workflows should therefore be as simple and comprehensible as possible.

                Digital workflows with the open source platform Apache Airflow

                Workflow

                Creating advanced workflows in Python

                In Apache Airflow the workflows are created with the programming language Python. The entry hurdle is low. In a few minutes you can define even complex workflows with external dependencies to third party systems and conditional branches.

                Schedule, execute and monitor workflows

                The program-controlled planning, execution and monitoring of workflows runs smoothly thanks to the interaction of the components. Performance and availability can be adapted to even your most demanding requirements.

                Robust orchestration of third-party systems

                Already in the standard installation of Apache Airflow numerous integrations to common third party systems are included. This allows you to realize a robust connection in no time. Without risk: The connection data is stored encrypted in the backend.
                Scaling

                Ideal for the Enterprise Context

                The requirements of start-ups and large corporations are equally met by the excellent scalability. As a top level project of the Apache Software Foundation and with its origins at Airbnb, the economic deployment on a large scale was intended from the beginning.

                A glance at the comprehensive intuitive web interface

                A major advantage of Apache Airflow is the modern, comprehensive web interface. With role-based authentication, the interface gives you a quick overview or serves as a convenient access point for managing and monitoring workflows.

                The orchestration of third-party systems is realized through numerous existing integrations.

                Flexibility by customization

                The adaptability is given by numerous plugins, macros and individual classes. Since Airflow is completely based on Python, the platform is theoretically changeable up to the basics. Adapt Apache Airflow to your current needs at any time.

                Truly scalable

                Scaling with common systems like Celery, Kubernetes and Mesos is possible at just any time. In this context a lightweight containerization can be installed.

                20_HG_R_Kosten

                Completely free of charge

                The workflow management platform is quickly available without license fees and with minimal installation effort. You can always use the latest versions to the full extent without any fees.

                Benefit from a whole community

                As the de facto standard for workflow management, the Airflow Community not only includes users, but the platform also benefits from dedicated developers from around the world. Current ideas and their implementation in code can be found online.

                State-of-the-art workflow management with Apache Airflow 2.0

                The new major release of Apache Airflow offers a modern user interface and new functions:

                • Fully functional REST API with numerous endpoints for two-way integration of Airflow into different systems such as SAP BW
                • Functional definition of workflows to implement data pipelines for improved data exchange between tasks in the workflow using the TaskFlow API
                • Interval-based checking of an starting condition with Smart Sensors, which keep the workload of the workflow management system as low as possible
                • Increased usability in many areas (simplified Kubernetes operator, reusable task groups, automatic update of the web interface)

                Automatic file transfer

                Due to the large number of integrations to other systems, the transfer of data and files can be easily realized. So-called sensors are used to check start conditions such as the existence of a file at periodic intervals. For example, a CSV file can be loaded from the cloud service into a database. In this way, unnecessary manual work can be automated.

                Executing ETL workflows

                Your data management will benefit the most from Apache Airflow. It has never been easier to combine different, structured data sources into one target table. Originally Airflow was developed according to the needs of Extract-Transform-Load (ETL) workflows and offers smart concepts like reusable workflow parts to build even complex workflows fast and robust.

                Triggering of external process chains via API

                If there is no easy way for system integration per task operator (and the community has not provided a solution yet), the connection via APIs and HTTP Requests is still possible at any time. For example, a process chain in SAP BW can be started and tracked synchronously. Conversely, system integration through Airflows excellent API is possible without any problems.

                Implement Machine Learning process

                Not only during the development of a Machine Learning application many processes which are ideally implemented as a workflow exist. The productive execution of a model can also be implemented as a workflow and thus provide, for example, current forecast data at fixed intervals. The data preparation and training of the current model version can be easily realized with Airflow.
