> The main motivation to migrate was cost. Is Fly.io really than much cheaper for hosting CDN/Postgres/Docker Container?

I saved about 25% from Heroku, but fly is much less reliable. I've had TLS certs expire without warning and redis has timeouts

    This was the problem I was experiencing: https://community.fly.io/t/redis-socketclosedunexpectedlyerror-socket-closed-unexpectedly/5897 https://community.fly.io/t/redis-socketclosedunexpectedlyerr... Taking this thread's advice, I started self-hosting on flyio and have only seen 1 timeout in ~2 months.

  Did we diagnose the TLS certs expiring? This is most often something like a CAA record that fails invisibly. We're not very good at notifying you of these kinds of issues, but certs should always renew when the config remains good. People who proxy through cloudflare hit this a lot, unfortunately.

    CF is my DNS. Not sure if I had the proxy enabled. I was able to re-configure everything and it started working. I made a reminder to check around the 65 day mark to see if it successfully renews. I suspect what may have caused the issue is I have multiple fly hosts on subdomains, but each subdomain had a wildcard certificate against the root (*.example.com).

  do they claim to warn about TLS certs and pending expiration? (i haven't found that in docs anyway)

    With Heroku, I never had to think about expiring certificates. With FlyIO, my app was down for 4 hours and I only new about it because of 3rd party uptime monitoring. Here are a few support issues with this problem: https://community.fly.io/t/ssl-certificate-did-not-renew-automatically/4924 https://community.fly.io/t/ssl-certificate-did-not-renew-aut... https://community.fly.io/t/certificate-expired/9143 https://community.fly.io/t/certificate-expired/9143 https://community.fly.io/t/ssl-cert-expired-and-did-not-renew/2136 https://community.fly.io/t/ssl-cert-expired-and-did-not-rene...

  I tested websocket on fly about 2 years ago, it seemed to have kinda weird characteristic. It's hard to explain because I can't dig it. It's like throttle + batch scheduling somehow (I don't know what it actually does though) I tested Fly, DO app platform, Render. Ended up with DO (but it's meh, can't mount disk volume, can't deploy to a specific sha code git) I'm going to [stress]test their wss:// again this year, I'm thinking to finally move a commercial one to fly (already have hobby apps there)

I moved a service that was costing me $300+/mo to Fly and this month it was like $15. Some months I fall under the minimum $5 billing threshold and it is just free. They are the only provider that has nailed the killer feature: turn off shit while it isn't in use.

  This. We have a similar situation with Azure services being gradually migrated to Fly. Stuff that costed us $200+ to do on Azure is just like $15 on Fly.

  Yeah, I sometimes wonder if they bill me correctly. Their price is not that cheap but at the end of the day, the cost is lower than expected.

We saved about 50% of our monthly bill migrating from AWS to Fly.io. While Fly.io isn't cheap, it's certainly cheaper than AWS from my experience.
