Last updated: 2020-05-08 18:24:19

    Feature Overview

    You can group cross-region and cross-project instances of a Tencent Cloud product for unified management. When creating a large number of instances, you can create instance groups as needed to better manage instances, configure alarm policies, and improve OPS efficiency.

    Use Cases

    • Alarm policies can be configured for cross-instance and cross-region projects of the same product in a unified manner.
    • You can manage various resources under your Tencent Cloud account by service category.

    Notes

    • Each instance group can contain up to 2,000 instances, and a maximum of 200 instances can be added to an instance group at a time.
    • By grouping instances, you can manage cross-region and cross-project Tencent Cloud products in a unified manner and configure alarm policies, avoiding repeated operations and improving OPS efficiency.
