Fly, A possible alternative to Heroku: christine.website/blog/fly….

However, I can confidently say that fly.io seems like a viable inheritor of the mantle of responsibility that Heroku has left into the hands of the cloud. fly.io is a Platform-as-a-Service that hosts your applications on top of physical dedicated servers run all over the world instead of being a reseller of AWS. This allows them to get your app running in multiple regions for a lot less than it would cost to run it on Heroku. They also use anycasting to allow your app to use the same IP address globally. The internet itself will load balance users to the nearest instance using BGP as the load balancing substrate.
