Preemptible VMs

Preemptible instances are instances that may be terminated at any time. This can occur in two cases:

• If 24 hours have passed since the instance was started.
• If there are insufficient resources to launch a regular instance in the same availability zone. The probability of termination is low, but varies depending on the day.

Preemptible instances are available at a lower price than regular instances. However, they don't provide fault-tolerance.

Restrictions

In addition to the fact that preemptible instances can be forcibly stopped, they have the following limitations:

• If there aren't enough resources in the specified availability zone to launch a preemptible instance, it won't launch.
• A preemptible instance can't be turned into a standard VM and vice versa.
• Preemptible stances aren't subject to an SLA.

How to work with preemptible instances

To create a preemptible VM, follow the instructions.

The instance isn't deleted after it's stopped and all its data is saved. When you need the instance again, start it again.
