Google Offers Beta Availability of Sole-Tenant Nodes


While making a move that shows it's committed to improving cloud technologies for customers, Google recently announced beta versions of sole-tenant nodes for companies using virtual machines. The virtual machines are also known as instances, and companies typically have to share physical servers for their virtual machines.

However, the availability of Google's sole-tenant nodes means sharing is no longer a requirement. This new option allows using instances in the same ways as before, except on server capacity that is only allocated to one customer.

How Could Businesses Benefit From This Service?

Some companies rely on sole-tenant nodes to create a physical separation of instances for different projects or users.  Corporate virtual computing environments can fit into an organization's overall data protection strategy by deploying a virtual machine on employees' devices and ensuring they only have access to appropriate kinds of data.

When dealing with workers who have different credentials, separation provided by single-tenant nodes could be advantageous.

Sole-tenant nodes can also separate workflows. That's sometimes necessary for businesses to do if handling certain kinds of data, such as payment details. Companies can ensure compliance by keeping workloads related to confidential content away from workloads that do not have that type of information.

Google's sole-tenant nodes also support multiple virtual machine types on one piece of hardware. Each node has a virtual machine memory and CPU limits, but it's possible for users to combine several virtual machines until reaching that cap.

Moreover, Google's sole-tenant nodes offer an autoscaling feature for managed instance groups. You set an autoscaling policy for the group, then the autoscaler removes or adds instances based on the current load.

So, if your company uses applications on a variable basis, the autoscaler detects when it's necessary to increase resources and doesn't waste them when they aren't needed. That feature helps keep costs down for your business.

Sole-tenant nodes reduce downtime, too. That's because they're capable of live migration, allowing site maintenance to happen without causing outages.

Amazon Offers a Similar Service

In 2011, Amazon offered a sole-tenant service of its own known as Dedicated Instances. Amazon clarified that there was no guarantee all sole-tenancy instances associated with a company would be on the same piece of hardware but that at least all sole-tenant hardware related to a given client has isolation as a primary characteristic.

And in fact, it is often preferable for the instances to get spread out across multiple pieces of hardware in case of a failure.

Amazon's Dedicated Instances service comes with a $10 per hour charge when users have at least one instance in a region. In contrast, Google's service differs by charging people a per-second rate for the nodes used and mandates a minimum duration of at least one minute.

Also, Google gives users the choice to choose the location of their nodes manually. That theoretically means that businesses could have all their instances residing on one piece of hardware if desired. Ordinarily, though, Google uses a placement algorithm that automatically finds the best location for an instance.

Companies Can Get Started Now

It's possible to launch virtual machines using sole-tenant nodes from the Google Cloud SDK or the Compute Engine APIs. Soon, Google will also offer support for Google Cloud Console.

Companies may avail of sustained use discounts if the amount that they depend on sole-tenant nodes is greater than the minimum amount. There are also price-related benefits for enterprise customers currently in cloud-related contracts with Google for at least a year or those who decide to enter into them now. Those are also known as committed use contracts.

Google Reemphasizes Its Focus on the Cloud

This latest offering is an example of how Google demonstrates to its enterprise customers that it's serious about providing the cloud tools they need to do business better. Even though the service is only in beta, businesses can still determine if it meets needs.
