Situation
The OpenEMR license of OpenEMR on AWS prevents running the OpenEMR Webserver on the current burstable instance type T3.
The OpenEMR license of OpenEMR on AWS restricts that the OpenEMR Webserver must be on a T2 instance, which is being deprecated by AWS. T3’s are not allowed due to the OpenEMR AWS Marketplace license restriction that the webserver instance must be on a T2. Note that the MySQL database can run on a T3.
Over the past 3 months or so I have seen spot instances of EC2 T2 instances are being shut down occasionally (sometimes daily, sometimes every 2 weeks) due to a lack of capacity on all US domains. This is an annoyance because our EMR is being occasionally shut down (it can usually be restarted immediately).
I asked AWS support about this, and they recommended switching to on-demand instances (increases my cost by several hundred dollars per month - great idea Amazon lol ) or switching to T3’s, which, of course, I cannot do. This license restriction needs to be removed.

Logs
Did you check the logs? Yes.
Was there anything pertinent in them? The EC2 spot system is shutting these instances down. A reason is not given by the “spot instance” events. The “spot instance” support team confirmed that they are being shut down due to a lack of capacity by AWS.
