I run a python flask app on Docker on AWS EC2. Including Dozzle (logs), Beszel (monitoring) and Unami (analytics). Runs on three t4g instances. One being a dedicated caddy exposed to the internet, one being a NAT gateway (self managed) and the main Docker worker host (private). All in cost is $35 a month. You’re splitting hairs and being the typical overly frugal developer instead of founder mode if you optimizing dollars when you have $20k / mo revenue.

What do I get as an advantage being on AWS? S3 (literally like a $1 month) SQS (free tier) and Lambda (async jobs; free tier). Capacity if needed, just scale up t4g instances.
