I have set up Container Service environments for various clients using different cloud providers, including AWS. I have used the Amazon Elastic Container Service in this capacity.
One of my clients from Israel is running web-based applications that are using PostgreSQL as the backend database connection. I think that it is a user-learning software, and they provide it to big companies to give KT sessions for new employees.
They use the Totara application and for that, we have set up the infrastructure including VBA and database applications. We also manage their Amazon Route 53, and we have set up Jenkins for CICD purposes.
