I thought the linked article about how Khan Academy eventually migrated to multiple services was a good example of when introducing micro services is a good idea:

They had already scaled the mono service about as far as it could go and had a good sense of what the service boundaries should be based on experience.

What about when it’s you breaking your own thing?

A very large code base full of loosely related functionality makes it more and more likely a change in one part will break another part in unexpected ways.

Well in that case you won’t need tools like Cursor either.

Just vibe code away and never look at the source it’s generating.

If you can serve all your traffic by a single instance running Sqlite in same process as your application, have at it.

If you need to serve your dats across a network to many clients, managing that with SQLite is much trickier.

Which is also a reason to not use Databricks, as they will cost your company money by selling gullible users things they don’t need.

You need all that stuff when you need to scale. For an MVP you can get away with very little.

It depends on how you deploy it.

Django on Render( and presumably a heroku) just works.

It's still much more work that just dropping in a Firebase url. Firebase can lead to poor design choices and come back to bite you, but hopefully by then you've already raised a few VC rounds and you're rolling in dough.

> Maybe a NoSql DB that “understands” the Postgres API?

I believe there are several of these already, like Cockroach DB.

Can someone translate this to non-CEO speak?

You basically pay databricks a “fee” to choose the more appropriate and modern stack for you to build on, and keep it up to date. Never used it, but it handles with lots of the administrative bs (compliance, SLAs, idk) for you so you can just ship.

Damn they trained a model that so deeply embeds human experience it actually feels hunger, yet self aware enough it knows it’s not capable of actually eating!

That’s like a Black Mirror episode come to life.
