In this article, we explore AWS Managed Workflows for Apache Airflow—a fully managed orchestration service that lets you programmatically author and schedule workflows using Apache Airflow without the hassle of managing underlying infrastructure.

Amazon Managed Workflows for Apache Airflow (MWAA) takes care of provisioning, scaling, and managing the Apache Airflow instance. As your workflow execution demands increase, MWAA automatically allocates additional resources, simplifying the setup, configuration, deployment, and ongoing management of your workflows. This managed service not only reduces operational overhead but also ensures reliability with features such as automatic scaling, high availability, and fault tolerance.

Note

When you create an Apache Airflow instance in AWS, you are essentially receiving the same open source Apache Airflow—but managed in the cloud. Simply upload your directed acyclic graphs (DAGs) defining your data pipelines to an S3 bucket, and Apache Airflow orchestrates the extraction, transformation, and loading (ETL) of your data.

The image is a diagram illustrating the components and workflow of Amazon MWAA (Managed Workflows for Apache Airflow), showing stages like extracting, transforming, loading data, and learning through analytics and machine learning. It includes elements like Amazon S3, directed acyclic graphs, and various data destinations such as analytics, storage, and databases.

Key Benefits and Features

Amazon MWAA offers several advantages that allow you to focus on building robust data pipelines rather than managing infrastructure. Key features include:

Managed Infrastructure: AWS provisions and maintains the Apache Airflow instance, eliminating the burden of server upkeep.
Security: The environment is secured using Amazon VPCs and encrypted automatically with AWS KMS.
Monitoring: System metrics and logs from Apache Airflow are sent directly to Amazon CloudWatch, facilitating efficient monitoring of task delays and workflow errors across multiple environments.
AWS Integrations: MWAA integrates seamlessly with a variety of AWS services such as AWS Athena, Batch, DynamoDB, DataSync, EMR, Firehose, Glue, and Lambda, enabling you to build intricate workflows that harness the full ecosystem of AWS capabilities.

For a comprehensive list of supported AWS service integrations within Apache Airflow, please refer to the official MWAA documentation.

Use Cases

Apache Airflow is well-suited for constructing and managing complex data pipelines. Common use cases include:

Scheduling and executing workflows to process and prepare intricate datasets.
Orchestrating multiple ETL processes that involve diverse technology stacks.
Automating pipelines for data ingestion, transformation, and loading to power machine learning models and analytics platforms.
