Leveraging Apache Airflow on Oracle Cloud Infrastructure (OCI)

Introduction: Apache Airflow is a popular workflow orchestration tool used for scheduling, monitoring, and managing workflows and data pipelines. As cloud adoption continues to grow, many organizations are exploring its implementation on Oracle Cloud Infrastructure (OCI). In this blog, we will explore whether a managed Apache Airflow service is available on OCI, best practices for building and configuring an Airflow cluster on OCI, and a detailed approach to migrating Apache Airflow workloads from AWS to OCI.

1. Is There a Managed Airflow Service on OCI?

As of now, Oracle Cloud Infrastructure (OCI) does not offer a fully managed Apache Airflow service similar to AWS Managed Workflows for Apache Airflow (MWAA) or Google Cloud Composer. However, OCI provides a robust infrastructure to run Airflow through services like:

• OCI Compute Instances: Provision virtual machines to host Apache Airflow.
• OCI Kubernetes Engine (OKE): Deploy Apache Airflow in a containerized format using Helm charts.
• Oracle Functions and Oracle Container Registry: Store containerized Airflow instances and run specific tasks using serverless components.

2. Best Practices for Building an Airflow Cluster on OCI

When setting up an Apache Airflow cluster on OCI, consider the following best practices to ensure scalability, reliability, and cost-efficiency:
