Application publishing limits
Web and mobile visualization applications developed in IoT Studio must be bound to a custom domain name. If you publish an application without binding a domain name, the access link is valid for only 24 hours and cannot be used in a production environment. Therefore, bind a custom domain name to your completed applications as soon as possible.
You are responsible for the storage and security management of your custom domain names. Pay close attention to the security risks of your applications to prevent attacks from affecting their operation.
