Connecting your Lambda Function to a Private Database
If you want your Lambda function to interact with resources (e.g., RDS database, EC2 instance) inside a private subnet, you won't be able to do so by default. The reason for this is that Lambda functions live in an isolated and secured VPC managed by AWS. This is why when you create a Lambda function, you don’t go through any networking configurations (VPC, subnet, ENIs), unlike when creating EC2 instances. Also, you cannot establish [...]

AWS can generate one for you automatically, and then you define the permissions you want it to have after. Most of the time, that's the case. However, there are instances when you might choose to associate an existing IAM role. In [...]
