How do we support > 20 concurrent users? In OHDSI tutorials with > 20 users, the system becomes unresponsive. We need tests that can put the application under a load that simulates a training session (for example).
How do we want to support different architecture(s) (i.e. cloud first?)? Need to survey the OHDSI community to understand how they have deployed ATLAS, if they can't/won't deploy ATLAS why not?
Per https://whichjdk.com/, we should aim to adopt Java 21 which is the current LTS version.
This would allow us to upgrade to Tomcat 11: https://tomcat.apache.org/migration-11.0.html
