Application Deployment
General DNS Resolution
The DNS service enables visitors to access your service resources, such as ECS, OBS, RDS, and ELB using domain names.
Advantages
-
High Concurrency
Tens of millions of concurrent queries on a single node
-
Multiple Record Types
Supporting all of the most commonly used record types
Service Management
You can 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 online.
-
Easy Maintenance
Test the offline service in a VPC without interrupting online applications.
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.
Advantages
-
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.
