I’m in a similar boat. I’m a sysadmin supporting a legacy application running on AWS EC2 instances and a new ‘serverless’ microservice based platform as well. It’s really really hard to scale and optimize anything running on EC2s unless you really know what you’re doing or the application is designed with clustering in mind.

You tend to end up sizing instances based on peak load and then wasting capacity 90% of the time (and burning through cash like crazy). I can imagine a lot of Lemmy admins are overspending so fast they give up before they figure it out.
