What are Preemptible VMs?
Preemptible VMs are highly affordable, short-lived compute instances suitable for batch jobs and fault-tolerant workloads. Preemptible VMs offer the same machine types and options as regular compute instances and last for up to 24 hours. PVMs offer significant savings, but normally, they would not be ideal for production or mission-critical workloads. Elastigroup for GCP changes that.
How it works
Based on historical and statistical data, Spotinst’s Elastigroup predicts preemptions ahead of time and automatically migrate instances into different machine Types, Zones or fall back to On-Demand in order to ensure high availability and consistency. Elastigroup will also make sure that the preemption is done gradually to ensure service uptime.
