Service Management

Service Management

Create public and private zones for the same domain names to deploy your website both online and offline with the same code, facilitating service maintenance.

Advantages

Smooth Deployment
Deploy the same services online and offline. Offline changes can be seamlessly updated to the online system.
Easy Maintenance
Test the offline service in a VPC without interrupting online applications.

Application Deployment

Application Deployment

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

Advantages

No Code Modification
If an ECS becomes faulty, you only need to change its IP address in the 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.
