DNS is fundamental to establishing and maintaining communications across network environments. If you have a hybrid network connectivity environment, you can share critical network services such as DNS and Active Directory without the operational burden of managing a distributed environment across accounts and virtual private clouds (VPCs). This approach helps you build and support applications that span a large number of accounts. For example, if you have hundreds or thousands of multi-Region accounts with hybrid connectivity requirements, you can share DNS services securely and efficiently across all connected environments within your AWS organization.
