What Apache Airflow is
Apache Airflow orchestrates data pipelines. Workflows are defined as DAGs in Python, and Airflow schedules them, runs their tasks in dependency order, retries failures and records what happened. It is the standard tool for scheduled data work at scale.
It is a multi-process system, and that shapes the server. A minimum installation is a scheduler, a webserver and a metadata database; anything beyond trivial adds workers and usually Redis or RabbitMQ as a broker. Each component holds a Python interpreter with your DAG code imported.
The subtlety that surprises people is DAG parsing. The scheduler re-parses every DAG file on an interval to detect changes, so heavy imports or slow code at module level in a DAG file get executed constantly — not when the task runs, but every parse cycle. A scheduler pinned at 100% CPU is almost always this rather than the tasks themselves.
Why run Apache Airflow on a VPS
Root access to tune scheduler parsing intervals and parallelism, which is where Airflow performance lives.
Workers and scheduler on one machine, or split across several as pipelines grow.
No per-task or per-DAG pricing.
Pipelines can reach databases on the same private network.

Recommended server
A starting point for Apache Airflow, not a hard floor — size it on the sliders.
| Memory | 8 GB — scheduler, webserver, workers and database each hold Python |
|---|---|
| CPU | 4 vCPU; the scheduler is busier than people expect |
| Storage | 80 GB; task logs accumulate quickly and need a retention policy |
| Operating system | Ubuntu 22.04 LTS |
How deployment works
Airflow is installed with PostgreSQL as its metadata database, a scheduler and webserver under a supervisor, and workers if you use the Celery executor. Keep DAG files light at module level — the scheduler re-parses them constantly, and expensive imports there are the usual cause of a pinned scheduler. Configure log retention early.
What people run it for
ETL pipelines
Scheduled extraction and loading with dependency ordering and retries.
Report generation
Multi-step reporting where step three must wait for step two.
ML pipelines
Training and evaluation runs on a schedule, with history.
Replacing cron
Scheduled jobs that have grown dependencies cron cannot express.
