Amazon Route 53 is the managed Domain Name System service of Amazon Web Services. It translates domain names into IP addresses, routes users to application endpoints using routing policies, checks endpoint health and sends traffic only to healthy targets. The service also offers domain registration, private DNS inside virtual networks and a DNS firewall. It runs as a service within the AWS cloud.
Amazon Web Services, Inc. is a US company. Under the US CLOUD Act, a US provider can be compelled to disclose data within its control, wherever that data is stored, which is the central sovereignty question for this service. AWS states that customers choose the geographic region in which their customer data is stored, and it offers a Data Processing Addendum to customers who need one. AWS's compliance pages do not, however, state where Route 53 data is stored, so organisations with strict requirements should check the contract terms and consider a European DNS provider.
