Today we talk to Mark Ericksen about all the things that we could be doing on the new platform - this is a follow-up to episode 50.

Mark specialises in Elixir, he hosts the Thinking Elixir podcast, and he also helps make Fly.io the best place to run Phoenix apps, such as changelog.com. In the interest of holding our new platform right, we thought that it would be a great idea to talk to someone that does this all day, every day, for many years now.

We touch up on how to run database migrations safely, and how to upgrade our application config to the latest Phoenix version. We also talked about some of the more advanced platform features that we may want to start leveraging, like the multi-region PostgreSQL.
