Aurora Serverless with API Gateway and Lambda is timing out

Question

I'm building a new project with totally serverless environment in AWS

I picked up API Gateway + Lambda + Aurora Serverless inside a VPC but Aurora cold start plus Lambda cold start is greater than API Gateway timeout of 29 secods

Is it possible to make any improvement to avoid such time out? Anyone has experienced this already?

Answer 1

Aurora Serverless V2 can easily scale from few to thousands of transactions in less than a second.

If you are using Aurora Serverless V1, we can set a minimum ACU to 1 and Don't pause compute capacity after consecutive minutes of inactivity (there is some cost)

Lambda cold starts can be avoided with provisioned concurrency .
