About preemptible VM instances on Google Cloud Platform (GCP)

This is Ohara from the technical sales department.

This time, I will write about billing for Google Cloud Platform (GCP).

Continuous use discount billing system

On Google Cloud Platform (GCP),
as stated on the official website https://cloud.google.com/pricing/  

We have a unique system called ``Sustained Use Discount,'' where

a discount of up to 30% is automatically applied to products that use Compute Engine or Cloud SQL and have a long execution period (Discount will be applied at the time of billing)

In other words, when running web content that requires constant operation on GCP,
discounts are automatically applied. (Discount will be applied at the time of billing)

Preemptible VM instances

If you look further at
https://cloud.google.com/pricing/  there is a machine type called "Preemptible VM Instance"

For the meaning and outline of the word "preemptive",
please refer to the following Wiki article:
https://ja.wikipedia.org/wiki/Preemption

A "preemptive VM instance" as defined by Google Cloud Platform (GCP)
is an instance that can be used at the standard "20%" charge. (80% off from regular billing.)

It is said that it is possible to operate continuously for up to 24 hours, but
it may be forced to shut down after a shorter period of time.

Even if a batch job is forcibly stopped, it can be re-executed, so
if you only need resources for a short period of time, you can use it at a low price.
(The job will slow down, but will not stop completely.)

// ENABLE PREEMPTIBLE OPTION gcloud compute instances create my-vm --zone us-central1-b --preemptible

This way,
you can immediately use it as a preemptible instance by simply typing --preemptible

 summary

This
is an overview of "preemptive VM instances" in "Google Cloud Platform (GCP)".
If you use it temporarily, it can also be used as a "development environment".
