What is Instance Groups?
Instance Groups is a component that enables you to create, use, and scale groups of same-type VM instances in the Yandex Compute Cloud infrastructure.
With Instance Groups, you can:
- Create groups with the required number of VM instances and performance parameters.
- Scale your computing capacity up or down, depending on the utilization.
You handle an instance group as a single entity in the Yandex Compute Cloud infrastructure. This enables you to manage internal settings of instance groups in line with your app requirements.
How do I calculate the cost of using instance groups?
Creating an instance group is free of charge.
All other Yandex Cloud services, e.g., creating VMs and allocating external IP addresses, are charged in the usual way.
How do I make sure I'm not overpaying?
To choose the right number of VM instances and minimize costs:
- Estimate the amount of computing resources required for your service and see the calculation examples and pricing policy for Yandex Compute Cloud.
- Regularly check your service load at various times throughout the day.
Why can't I delete a service account linked to my instance group?
You cannot delete a service account used to manage an instance group while it is linked to this group. First, update the service account in the instance group settings or delete the instance group and then delete the service account.
Can I install the required software on an instance in the group when creating that instance?
Yes, you can. To do this, specify a custom script with commands to install the required software in the metadata section of your new instance template. For more information, see Creating a VM with a custom configuration script.
