Restrictions on Backend Mounting ECS Server for a Single SLB Instance

Dear Alibaba Cloud user,

In order to ensure the full and reasonable utilization of resources, the number of servers that can be mounted on the SLB backend will be limited from February 13, 2018. The number of ECSs that can be mounted on the backend of a single SLB instance cannot exceed 200. There is no impact for the single SLB which already contains more than 200 backend server instances, but not more than 1000 maximum.

Feel free to open tickets if you have a reasonable business requirement.
