Keep it stupid simple. Use tech that you understand and minimize the layers of complexity between deploying, starting and troubleshooting an instance. For me, I like digital ocean droplet(s). Stupid simple IAM. SSH scripts for CI deployments. Everything sits behind a Cloudflare cache. The backend sends key events like restarts and fatal errors into a dedicated Slack channel. Its my confirmation a deployment worked and first alert if something crashed. My business partner and I are currently running a $1m/arr business with this setup on a single digital ocean instance, Python3 and Nuxtjs.
