New for AWS Lambda: Use Any Programming Language and Share Common Components

That's not for in-VPC functions, although if the underlying instance changes with firecracker migration users might see ENI start improvements. Currently your ENI usage is roughly floor(3GB/Memory Allocation)*(Concurrent Executions). If the 3GB changes users will see huge gains as each ENI creation can take around 9s.

Why would you use VPC functions?

Mostly due to being forced. For example: serverless aurora forces a VPC on you.

With delays as bad as 8+ seconds for ENI attachment, this is a significant holdback (https://medium.freecodecamp.org/lambda-vpc-cold-starts-a-lat...)

I believe you can now use Aurora Serverless outside of a VPC by using the new Data API endpoint.

You indeed can, but it's beta (us-east-1 only at the moment) and leaves a lot to be desired (https://www.jeremydaly.com/aurora-serverless-data-api-a-firs...)

Ah okay, I never thought about using an SQL DB.

True. In-VPC has extra costs.
