BlogI Just Saved a Bunch of Money by Switching to Nutanix


The hybrid cloud marks another significant step in our commitment to enable organizations to deliver a multi-cloud strategy as part of digital transformation. In conversations with our customers, we often hear of their challenges incorporating hybrid cloud assets into their IT management landscape. Many IT organizations are surprised by the unexpectedly high costs of their cloud services and find it challenging to achieve adequate usage governance across the organization. As a cloud architect, my first recommendation to them is to read our white paper on The Rise of Cloud Native Computing.

Public cloud customers will spend more than $50 billion on infrastructure as a service (IaaS). This boom is, of course, due to the broader adoption of AWS, Azure, and GCP cloud services, but it is also caused by all the ancillary costs associated with public cloud infrastructures. The growth in spending is now often exceeding the growth in the actual business. That is because a large portion of what companies are spending on cloud is wasted. Not surprisingly, cloud costs and complexity expand as infrastructure grows.

Why is controlling costs in the public cloud so challenging? The primary reason we often see is due to either orphaned resources, misappropriation of cloud resources, and idled instances. Orphaned resources occur when a virtual machine is terminated, but resources attached to that machine continue running or existing, which incurs wasted costs. This can also be from unassociated IPs, orphan snapshots, unused machine images to development/testing/QA environments that are left running.

Another source of wasted cloud spend is overprovisioned infrastructure. Our experience tells us about 30% of instances are sized at least one size larger than needed for their workloads. Just by reducing an instance by one size, the cost is reduced by 50%. Downsizing by two sizes saves 75%! Whether it’s because you selected the largest size by default or because your needs have changed, you may be paying for resources in much larger sizes than you actually need.

Mis-appropriation of cloud resources is also fairly common. Many cloud users select “on-demand” resources by default, whereas most consistent workloads would benefit from using Reserved Instances in AWS or Azure or Committed Use discounts in GCP. In this same vein, batch processing could run on discount options like AWS Spot Instances, Azure Low-Priority VMs, or Google Preemptible VMs. Across all cost-saving guidelines that exist for assessing the maturity of hybrid cloud operations, ASG always stresses the need for consistency, visibility and automation across all environments, including private, public, and especially hybrid cloud environments. And that’s where Nutanix comes in.

The Nutanix Enterprise Cloud OS enables organizations to automate application provisioning and lifecycle management across multiple clouds. Using solutions such as Calm and Xi Beam, Nutanix provides our customers with added business-level insights to deliver automated provisioning, governance and cost optimization across their hybrid cloud. Xi Beam goes well beyond cloud provider-based optimization tools as it provides holistic cloud analytics, centralized cost governance, intelligent consumption planning, and security compliance for your entire cloud environment. You can quickly identify and eliminate underutilized resources, compare cloud vendors, provision the optimal instances for each application, including real-time security to identify critical cloud infrastructure vulnerabilities as well as their recommended remediation.

But why stop there? With cost and governance under control, why don’t we examine the cost-saving deployment of Nutanix Xi Frame, their desktop-as-a-service (DaaS) solution? Nutanix Frame is the easiest way to run virtual apps and desktops on your choice of infrastructure using any browser and any device. IT enterprises are leveraging VDI for lower administrative overhead and, no surprise, for its cost savings. But unfortunately, data file access problems often create additional issues because file servers need to provide access to user profile data and end-user file shares. Thankfully, Nutanix Files, a fully integrated file server solution, solves this problem and lets you get the most out of your DaaS, with excellent desktop performance, enterprise-grade availability, and cloud-like flexibility. Xi Frame with Nutanix Files provisions thousands of virtual desktops in minutes. If you don’t believe me,  you can check it out here.

Because of Nutanix Enterprise Cloud solution, IT can deliver true consumer-grade simplicity that makes infrastructure management effortless and, most importantly, cost-effective. As a final thought, one of the most important things for businesses considering moving their data center applications and services to hybrid cloud architectures is to work with an experienced hybrid cloud expert like ASG to make sure you get all the cost-savings you deserve.
