The MWAA is what we can call the "Airflow of AWS". In its default operation, it stores numerous metrics in CloudWatch that can be very costly in the long run, I configured MWAA to generate only a few metrics relevant to the business. In addition, I modified the way it reads the configuration files of the pods in the Kubernetes that it used to run the DAGs.

All this generated a cost reduction of more than $2000 per month.
