Sign up free — no credit card requiredAWS IoT Core now supports customer managed domains in the AWS GovCloud (US) Regions. Customer managed domains (also known as custom domains), allow you to configure custom domain names, use your own server certificates stored in AWS Certificate Manager, attach custom authorizers , and create multiple data endpoints for your account. Custom domains provide long-term stability of TLS behavior, domain names, and their trust chain for device deployments. They also help you enable separate domain configurations for heterogeneous device fleets, and simplify migration of existing devices to AWS IoT Core. For example, by configuring custom domain names and custom authorizers for your data endpoints, you can keep using the same domain names and authentication methods your devices already know. This means you don't need to update device credentials or CA certificates during migration to AWS IoT Core, minimizing software updates on devices already in the field. With the expansion to the AWS GovCloud (US) Regions, this feature is now available in all AWS regions where AWS IoT Core is present.
