Database Decision Tree
On https://git.cloud.safran/safrangrp/cloudsafran/cloud/gcs-docs/-/blob/main/docs/standard/refarch/Databases/databases.md , the decision tree does not take into account the "cost" of Aurora against A RDs with postgre or Mysql, since the first entry is based on the engine needs.
In a project where we have a "small" need of a relationnal database, it seems it is prefered for cost issue to have a PostgreSQL / RDS instead of an Aurora PostGresql syntax service.
MAybe ot would be better to add this into this tree or as a remark on this page.
