Reduce the Google Compute Engine Cost with 5 Tricks

Google Compute Engine Cost

Compute Engine provides several options for cutting expenses, such as optimising your infrastructure and utilising sales. Google Cloud is sharing some useful advice to help you save Google Compute Engine cost in this two-part blog post. This guide has something for everyone, regardless of whether you work for a huge organisation trying to optimise its budget or a small business just starting started with cloud computing.

Examine your present budgetary plan

It would be helpful to have a map of your present circumstances and spending structure before you embark on a journey to optimise your Google Compute Engine cost. This will allow you to make well-informed decisions regarding your next course of action. That billing panel is the Google Cloud console. It provides you with a detailed breakdown of your spending, tracking each expense to a specific SKU. It can be used to examine the overall financial picture of your company and to determine how much a given product will cost to use for a given project.

You can find resources you are no longer paying for but no longer require by taking a closer look at your spending. Nothing is a better method to save money than simply not spending it, after all.

Examine the automated suggestions

On the page where your virtual machines are listed, have you noticed the lightbulbs next to some of your machines? These are Google Cloud’s automated suggestions for things you could do to cut costs. The following project management categories cost, security, performance, reliability, management, and sustainability are addressed by Recommendation Hub, a new technology. The recommendations system can make suggestions for actions that you might think about based on its understanding of your fleet structure. Helping you cut costs without sacrificing fleet performance is Google Cloud’s main objective.

The machine can be scaled down according to its utilisation, or the type of machine can be changed (e.g., from n1 to e2). You get a summary of the recommended modification along with the expected cost savings when you click on one of the recommendations.  You have the option of applying the modification or not. Recall that the instance must be restarted in order for modifications to take effect.

Check the types of discs you have

You must attach at least one persistent disc to each virtual machine in your fleet. Google Cloud offers a variety of disc formats with varying features and performance. The kinds that are offered are:


With a full range of data durability and administration features, Hyperdisk is a scalable, high-performance storage solution built for the most demanding mission-critical applications.

Hyperdisk Storage Pools 

Hyperdisk Storage Pools are pre-aggregated volumes, throughput, and IOPS that you can reserve in advance and allocate to your apps as required.

Persistent Disk 

Your virtual machines default storage option is called Persistent Disc. It may be regional or zonal. has four variations:


The desktop computer’s equivalent of an HDD disc. offers the least expensive storage with a slower I/O speed.


A speed-focused option with excellent I/O performance, albeit at a higher cost per gigabyte.


The default setting for newly created compute instances; it strikes a compromise between “Standard” and “SSD.”


Suitable for the hardest workloads. enables you to manage the disk’s IOPS in addition to its size.

Local SSD

An SSD that is physically attached to the host that powers your virtual machine is called a local SSD. incredibly quick but transient.

Since persistent disc storage is the most widely used type of storage, let’s concentrate on it. The Balanced disc, which offers a decent compromise between performance and cost, is the default disc type used when building a new virtual machine. Although this works well in a lot of situations, it might not be the ideal choice in every situation.

Fast I/O to disc is not needed, for instance, by stateless apps that are a component of auto-scaling deployments and keep all pertinent data in an external cache or database. These apps are excellent candidates for switching to Standard discs, which, depending on the region, can be up to three times less expensive per gigabyte than Balanced discs.

A list of the discs used in your project can be obtained using: the list of gcloud compute discs with the format “table(name, type, zone, sizeGb, users)”

You must clone the disc and make changes to the virtual machines that use it in order to start using the new disc in order to alter the disc type.

Free up any unused disc space

Moving on to storage, there are other factors besides disc type that influence price. You should also consider how much disc utilisation affects your budget.You will be paid for the full 100 GB of persistent disc space allocated for your project, whether you use 20%, 70%, or 100%. You may still want to monitor your boot discs closely even if your application does not use Persistent Discs for data storage.

If your stateless programme really needs a disc with many gigabytes of free space, think about reducing the size of the discs to match your actual needs. Because they enjoy round numbers, people frequently build 20 GB discs even when they only require 12 GB. Save money and act more like a machine.

Agree to make use of CUDs, or committed use discounts

Compute Engine is not the only product to which this advice is applicable. You can receive a significant discount if you can guarantee that you’ll use a specific number of virtual machines for three or more years, or at least a year! You can get substantially cheaper costs for local SSDs, GPUs, vCPUs, memory, sole-tenant nodes, and software licences by using a range of (CUDs). You are not even limited to allocating your vCPU and memory to a certain project, area, or machine series when using Flex CUDs.

Discounts for committed use are offered on a number of Google Cloud products. If you’re satisfied with Google Cloud and have no intention of switching providers anytime soon, you should seriously think about utilising CUDs whenever you can to save a lot of money. When it comes to computing, you can buy CUDs straight from the Google Cloud dashboard.
