If anyone is curious, I updated my Django / Docker starter app to use Django 5.0 at: https://github.com/nickjj/docker-django-example
It pulls together gunicorn, Celery, Redis, Postgres, esbuild and Tailwind with Docker Compose. It's set up to run in both development and production.
I personally use DigitalOcean but now that Hetzner is starting to get US data centers that is looking like a good option too.
With no other context, if I were creating a startup today I'd likely go with DigitalOcean.
AWS is also another option, especially if you think you'll be using some of their services.
But for a typical web app + SQL database + cache + object storage set up DO works nicely, although I would still use S3 for object storage even though DO has it, I find S3 to be more dependable.
