# Orchestrators

***

**AWS Step Functions**

* What it is: A serverless state machine. You draw a flowchart: "Start -> Run Lambda -> If Success, Run Glue -> If Fail, Send Email."
* Pros: Built into AWS, super cheap, event-driven.
* Cons: Proprietary to AWS (you can't take the code to GCP).
* Equivalents:
  * GCP: Cloud Workflows.
  * Azure: Logic Apps.

**Amazon MWAA (Managed Workflows for Apache Airflow)**

* What it is: Managed Airflow.
* Context: Airflow is the #1 tool for data orchestration globally. MWAA is just AWS hosting it for you so you don't have to install it on an EC2 server yourself.
* Equivalents:
  * GCP: Cloud Composer (This is the best managed Airflow service in the market).
  * Azure: Azure Data Factory Managed Airflow.
