Concepts Instance Groups
Instance Groups is a Compute Cloud component that lets you create and manage instance groups.
Instance Groups automatically identifies and corrects unhealthy instances in a group to ensure their optimal performance.
Warning
All operations in Instance Groups must be performed on behalf of a service account. For more information, see {#T}.
Each group consists of one or more instances of the same type. Group instances may reside in different availability zones and regions. More about the geo scope of Yandex.Cloud.

Integrate with Yandex Network Load Balancer and evenly distribute workloads across instances.
-
Create automatically scaled instance groups.
-
Automatically recover an instance if the application fails.
-

-
The template for deploying group instances.
-
Policies for scaling, deployment, and allocation.
