Instance groups
What is Instance Groups?
Instance Groups is a component that allows you to create, use, and scale groups of similar instances in the Yandex Compute Cloud infrastructure.
With Instance Groups, you can:
- Create groups with the required number of instances and performance parameters.
- Scale the computing capacity up or down, depending on the load.
You work with an instance group as a single entity in the Yandex Compute Cloud infrastructure. This allows you to manage internal settings of instance groups to meet 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, such as VMs and external IP addresses, are charged as usual.
How do I know I'm not overpaying?
To select the appropriate number of 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.
- Try to frequently monitor the load on the service at different times of day.
Why can't I delete a service account linked to an 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 a group instance when creating it?
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's template. For more information, see Creating a VM with a custom configuration script.
