I wonder what effect this may have for AWS Lambdas connecting to a DB for synchronous calls (e.g. through API gateway). The biggest issue with Lambdas IMO is the cold start time. If your Lambda is in a VPC the cold start time is around 8-10 seconds, and if you have decent security practices your database will be in a VPC. I know AWS said they would be working on improving Lambda VPC cold start times, but would like to know if using Aurora Serverless with these kind of "connectionless connections" would also get rid of the need to be in a VPC. I've used Aurora (and really, really liked it) but I haven't used Aurora Serverless.

came here wondering the same thing. those cold start times aren't acceptable for user-facing apps and i had to switch a serverless project from RDS in a VPC to dynamodb. even worse is that these cold start times are for each lambda, so if you've got concurrent usage then each new lambda spin up causes a cold start.

having said that, i'm actually pretty happy with dynamodb...so far.

Would it "get rid of the need to be in a VPC"? I think yes.

It looks like by enabling Data API, you expose that endpoint to the entire internet - which is secured like all the other AWS services with HTTPS, IAM, etc.

The beta version seemed like it had pretty poor performance: https://www.jeremydaly.com/aurora-serverless-data-api-a-firs... Does anyone have performance feedback now that it is no longer beta?

I'm definitely excited about this, especially after paying $36/month for a NAT that I barely used for a long, long time, and spending too many hours configuring it for my Lambdas.

That said, I don't know how Jeremy Daly got away with making that post, per AWS preview terms. They are pretty explicit about not posting benchmarks on their preview products, and that makes sense as the API is not stable at all.

Still, I'm glad to see the data and hope that the performance has improved. I wasn't accepted into the preview, and I've started work now to move most of our infrastructure to GCP. It notably does not require any fancy footwork to have a Cloud Function talk to a Cloud SQL instance https://cloud.google.com/functions/docs/sql#overview

Coldstart will be gone very soon—- you probably will be paying a little more though
