Network architecture design

A company has deployed new cloud applications and set up a site-to-site VPN connecting its internal data center to the cloud. The IT team wants internal servers to reach those applications without using public IP addresses. Which option is the best solution?

Explanation

Conditional DNS forwarding lets the data-center DNS server send queries for cloud-resource domains to a cloud DNS resolver, allowing internal servers to resolve and use the applications’ private IP addresses across the site-to-site VPN. Amazon Route 53 Resolver supports forwarding DNS queries from an on-premises network connected through a VPN to a VPC Resolver inbound endpoint.
