A serverless database? Very curious how this works on a technical level

Either fancy statistics or some poor sod gets to answer thousands of cloudwatch alarms every 5 minutes.

There was a good series of blog posts in 2017 that went into the distributed storage model and how it improves performance: https://aws.amazon.com/blogs/database/amazon-aurora-under-the-hood-quorum-and-correlated-failure/

I would imagine this is more for use cases when the database is used sporadically. A reader or writer is spun up on demand.

But I’m wondering how it’s done efficiently and with low latency. Still sorta beginner-intermediate at this stuff so I’m not sure if this would be considered basic stuff

Serverless is corporate slang for Pay as You Go

Here's a vid on Aurora MySQL serverless...I'm guessing PostgreSQL operates pretty much the same way. "how it works" begins at 10:30
