Is it possible to refactor it to use AWS Lambda so it's only using the compute power it needs, rather than maintaining infra? Aka, "serverless"
Then again, it's not like the hosting is costing that much. Actually I currently run it on a machine with lost of resources that is used for other things as well...so technically I could keep running it forever. That is to say the cost isn't the main driver for shutting it down. It's more a psychological burden at this point where I'm thinking "ok I tried, it didn't work time to move on".
