What is IGTM?
Tencent Cloud Intelligent Global Traffic Management (IGTM for short), can help users realize high concurrent load sharing of application services, health check of application services, and can implement fault isolation or traffic switching according to the health check results, which is convenient for users to flexibly Quickly build high-availability services such as multi-active in the same city and remote disaster recovery.
What does IGMT do?
1. Active and standby disaster recovery. When you deploy resources for your business, you configure both telecom IP and mobile IP. Normally, you use telecom. Once you find that telecom fails, you enable mobile. After the telecom is normal, switch back to telecom IP.
2. Live more. You have multiple IP pools serving users at the same time. If one of them fails, the fault will be identified in seconds and the faulty IP address will be removed. When it recovers, it will be added back to DNS resolution, IGMT will automatically switch, and the user will not be aware of the whole process. No operation and maintenance manpower is required.
3. Global traffic load balancing. You have used a multi-region CLB to achieve the effect of responsible traffic balance. You can use the IGTM health check function to detect the availability of CLB ingress in real time. When a certain region is unavailable, you can quickly find abnormalities and dynamically schedule traffic.
