If you had to use Amazon, sure. But the option would be nice.

That said, I’ve tried supporting both DynamoDB and an RDBMS with the same software and it was a pain, and this was for something with a less complicated schema then Mastadon. I think what’s missing here is really a scale-to-zero, serverless RDBMS (maybe Supabase or Neon fit the bill?)

I think having multiple deployment stack options will only help more adoption, and is a practical choice that will drive more decentralisation.

Decentralisation isn’t about never running things on a centralised stack. It’s about not having to.
