Google Cloud Spot VMs
June 30, 2025 - As the scale of public cloud infrastructure increased to meet overall demands, providers sought a method to utilize spare Virtual Machine (VM) resources. In 2009, Amazon introduced Amazon EC2 Spot Instances, where customers bid on unused or underutilized capacity. Google Cloud Platform (GCP) and Microsoft Azure followed suit and offered the same feature, albeit advertised under different names.

AWS has had this kind of spot instance for years, but with a 2 minute grace period rather than the 30 seconds GCP is offering. Azure and GCP both originally went with the 24-hour cutoff (which can easily be replicated on a regular spot instance if needed), but now GCP are backing off on that ... More on news.ycombinator.com

April 6, 2024Concerns with spot VM.
EDIT: I missed the announcement in October about GCP Spot VMs. Thanks for the update! Spot VM would be the AWS term. For reference, the same concept in GCP is called "Preemptive VM". I haven't personally used on for any prod GKE nodes, but have for GCE. Depends on the GCP region and season. Some GCP regions I can go for weeks without ever being preempted. Some GCP regions/times of the year you can't go for more than an hour without being preempted (this was not common). "Too disruptive" is subjective. If you have small run batch jobs with good orchestration, then even a VM running for that one hour would be just fine. If you have log running processes with a heavy penalty for interrupting a job, then it may be a poor fit for you. Note, that the longest runtime for a preemptive instance is 24 hours before you'd have to restart your VM. More on reddit.com

March 28, 2022[P] SpotML - Managed ML Training on cheap AWS/GCP Spot Instances
Why use AWS? The ROI of purchasing + colocation cost is ~6 months, and that's assuming you use spot instance with 70% reduction all the time. For some things cloud makes sense. GPU is typically not one. Unless you have a hard business requirement (e.g. compliance) or extremely fluctuating needs (e.g. you need 24 GPUs for a single day once a month), purchasing makes much more operational and economic sense.

June 6, 2025 - AWS may reclaim capacity with just a two-minute warning, after which the instance is stopped, hibernated, or terminated based on user settings. Google Cloud offers its users the opportunity to use Preemptible VMs and Spot VMs to lower their cloud resource costs by 60-91%. Both of these provisions offer discounted spare Compute Engine capacity in exchange for the possibility of interruption with very little notice.

AWS also imposes limits on the number of running and requested spot instances per account in one region. To learn more and understand how to increase these limits if necessary, refer to the AWS documentation on spot limits. Google Cloud Platform offers Spot VMs with fixed pricing, subject to no more than once-a-month pricing changes. When using Spot VMs in GCP, you need to consider CPU, disk, and GPU quota requirements.

r/googlecloud on Reddit: Why are Google Cloud spot VM prices so static compared to AWS?
April 6, 2024 -
Using the AWS spot pricing API, I've noticed that AWS spot instance prices fluctuate frequently (up to several times a day). However, Google Cloud spot pricing, retrieved via the Cloud Billing API, seems static for long periods. For example, the price returned for SKU 46CF-72FB-88FD (Nvidia H100 80GB Mega GPU attached to Spot Preemptible VMs in Virginia) was 7.220417 USD from 2024-06-08 until it finally changed on 2024-09-03. It feels like I must be doing something wrong when calling the API. Why is there so little variation in Google Cloud spot prices compared to AWS?
