I am trying to understand how to connect Vercel to Dynamodb and save costs on Data transfer. Is it possible to define VPC Between them? if vercel & dynamodb are in the same region, how much cost I will see from AWS Outside and Vercel inside?
I am expecting to know briefly the costs without surprices
While Vercel does run on AWS; at this point it does not support access to the underlying VPC that Vercel internally uses. Because of this limitation you will not be able to build a VPC to VPC peering.
That being said; DynamoDB pricing for Egress will be about $0.09 / GB billed at a monthly basis. So if you read 1 GB of data from DynamoDB apart from the Read and Write request units you will be charged $0.09 x Number of GBs data transfer out from DynamoDB.
For in-depth analysis on your data transfer; I strongly encourage that you enable AWS Cost and Usage report and look at the raw data gathered by it. You can also use AWS Cost Explorer for the sam purpose.
