Has anyone created any serverless api gateway + lambda system that was not exposed to the internet but only access from an on premise system through some dedicated connection like private connect? Looking at this https://aws.amazon.com/blogs/compute/integrating-amazon-api-gateway-private-endpoints-with-on-premises-networks/ it seems to be possible. I would have a VPC purely for connecting on-prem to AWS and allowing it to access the API gateway endpoint.
