Google Cloud Suspend/Resume accessible for cost optimization.

Google has made suspend and resume widely available tools. These tools provide you with greater control over Google Cloud Platform services. Suspending your Google Compute Engine virtual machine can preserve the current state, for instance, ‘s the disk, allowing the instance to return to where it had stopped when you restart it later. There is no need to spend money on cores or RAM when it is suspended. Instead, you’ll pay only the storage charges for the memory of your particular instance. Other operating expenses for VMs such as OS licensing could be reduced too.

What does it mean? Work?

Suspending an application will send an ACPI S3 alert for the OS. This results in two significant advantages over similar services provided by other cloud providers.

  1. Large compatibility variety of OS images without the requirement of installing cloud-based OS image or installing the daemon. Custom and non-documented OS images that interact with ACPI S3 signals. ACPI S3 signals are suitable for Suspend.
  2. Storage is automatically provisioned every time Suspend is requested. It does not depend on the boot disk used for the particular instance. This is distinct from other cloud implementations that require sufficient space on your boot disk to keep the current state of the instance. This can increase the operating expenses that you incur for the VM. This will also make sure that the suspended will use only the storage space required.
