Reply To: Question on Lambda connectivity to VPC hosted DB

[Jon-Bonso]

Hi Varun,

Take note that it is a common misconception that the “NAT was present already” simply because the Lambda function is working properly.

Please refer to the AWS documentation below:

By default, Lambda runs your functions in a secure VPC with access to AWS services and the internet. The VPC is owned by Lambda and does not connect to your account’s default VPC. When you connect a function to a VPC in your account, it does not have access to the internet unless your VPC provides access.
