Application Deployment

You can map private domain names to ECS IP addresses in specified VPCs, allowing these ECSs to communicate with each other using domain names.


  • No Code Modification

    Once an ECS is faulty, you only need to change its IP address in DNS records, instead of modifying existing configurations.

  • Free from DNS Spoofing

    Private domain names are not exposed to the Internet so you do not need to worry about DNS spoofing and attacks.

  • High Performance

    A private DNS server directly responds to requests for private domain names, greatly reducing network latency.
