Instance Groups is a Compute Cloud component that allows you to create and manage instance groups.
Instance Groups can automatically identify and heal unhealthy instances in a group to ensure their optimal performance.

Warning

To work in Instance Groups, you must use a service account. For more information, see Access.

Each group consists of one or more instances of the same type. Group instances may reside in different availability zones. Learn more about Yandex Cloud availability zones.

Group instances can also be part of a VM placement group. To enable this, when creating an instance group, describe placement group parameters in the instance template. You can create an instance group in a placement group using the CLI and API.

With Instance Groups, you can:

  • Simultaneously update all instances in a group.

  • Provide integration with Yandex Network Load Balancer and Yandex Application Load Balancer and evenly distribute workloads across instances.

  • Create automatically scaled instance groups.

  • Automatically recover a VM instance if an application fails.

  • Maintain the performance of application services in a reliable environment with multi-zone features instead of allocating resources for each zone.

  • Handle application stateless and stateful workloads.

When creating a group, you need to describe the following:

  • Template for deploying group instances.

  • Policies for scaling, deployment, and allocation.

An instance group created in a folder can be accessed by all VMs connected to the same cloud network. For more information about networking, see the Virtual Private Cloud documentation.
