Where do VDI costs hide? - A detailed TCO breakdown

What is TCO?

Total Cost of Ownership (TCO) is a critical metric used to evaluate the overall cost efficiency of software purchases. For IT teams, managing hardware tools for a distributed workforce can be costly. Virtual desktop infrastructure (VDI) offers a solution by providing remote-friendly, secure, and flexible work environments. This guide breaks down the components of TCO and provides actionable insights for optimizing VDI deployments.

TCO is used argumentatively in several business decisions to get a single-number view of how profitable or advantageous a certain software purchase can be for the problem they are trying to solve.

The intricacies of TCO are often vague and vary on several external and internal factors which need to be accounted for, to give a realistic and definitive view on the matter.

In this blog, we provide a comprehensive guide to understanding and defining your TCO for your most convenient alternatives while deciding your next VDI and where differentiated engineering can help with your cost efficiencies.

Phases of TCO

To arrive at a more factual narrative of your total cost of ownership with respect to virtual desktops, it helps to see the cost split across phases of deployment, owing to their uneven distribution.

The three phases of your average VDI deployment include Upfront CapEx, Deployment OpEx, and Ongoing OpEx.

CapEx (capital expenditure) represents a significant initial investment in assets that will provide benefits over multiple years. CapEx is capitalized on the balance sheet and expensed through depreciation over the asset's useful life.

OpEx (operating expenditure) refers to the ongoing costs incurred by a company for running its day-to-day operations. Unlike capital expenditures (CapEx), operating expenses are fully tax-deductible for the year in which they are incurred. OpEx is recorded on the income statement as an expense for the accounting period.

Introducing Neverinstall as an alternative to Citrix and VMWare offers a 60% higher cost-efficiency that enhances performance without sacrificing quality. Its modern architecture eliminates unnecessary components, improves latency, and ensures stable connections even at very low internet speeds, as we shall discover with a thorough analysis of the expenses through the first three years of use. By delivering substantial cost savings across setup, operational, and maintenance expenses, Neverinstall emerges as the most economical choice with its own performance edges.

Upfront CapEx

To establish a functional VDI environment and deliver virtual desktops, organizations must invest in the following critical components if they choose a traditional solution like Citrix or VMWare:

• Load balancer and VPN gateway for secure and efficient traffic management.
• Broker software for managing and provisioning virtual desktops.
• Microsoft Windows Server operating systems and SQL databases for backend infrastructure.
• Portal/enterprise storefront software for providing a user-friendly interface to access virtual desktops.
• Specialized IT Labor involved in configuration and monitoring software for managing and monitoring the VDI environment.
• Image management software for creating, updating, and deploying virtual desktop images. (Usually defers to applications like FSLogix)
• VDI licenses for the virtual desktop software.
• Hypervisor host licenses for the virtualization platform.
• Server and storage hardware for hosting the virtual desktops and storing data.
• Storage management software for efficient storage utilization and management.

The most consequential decision here relies on the hardware choice you intend to make for your organizational goals.

Based on the assumed usage and setup for a 100-user environment requiring an on-premises deployment, the following numbers have been calculated for the most popular options: Citrix, VMware, and Neverinstall. Other alternatives in 2024 include Parallels, Nutanix, Proxmox, and Workspot, among a few others.

Total Cost of Ownership (TCO)

Your TCO calculation should account for all these factors over a typical lifecycle of the hardware (often considered to be 3 years for such calculations):

• Initial purchase costs (hardware + auxiliary)
• Annual operating costs (maintenance + energy)
• Replacement costs at the end of the life cycle.

Choice of Hardware

Thin Clients vs. Full Desktops

Thin clients are generally favored for VDI/DaaS deployments due to their lower cost and minimal local processing requirements. Here’s a rough breakdown of the initial hardware costs:

• Thin Clients: ranges from $170 to $316 per device
• Full Desktops: Up to $500 per device

Auxiliary Hardware Costs

Initial expenses on auxiliary hardware (antivirus software, mice, speakers, etc.) total approximately $4,200 in the first year for setting up 100 workspaces at $42/user.

Operating Costs

• Maintenance Costs: This includes the IT labor and the hardware replacements that go into setting up, deploying, configuring and maintenance through the year.
• Energy Consumption: There's a significant difference in power consumption costs between your hardware options. Assume cost per KWHr to be around $0.17, taken as a global average.
  • Desktops: Approximately $2,543.20 per year for 149.6 KWHr
  • Thin Clients: Approximately $329.12 per year for 19.36 KWHr
• This stark contrast highlights the efficiency of thin clients in long-term energy expenditure.

Replacement Costs

Desktop replacement costs are 876% higher than those for thin clients. This substantial difference should be factored into the long-term financial planning and TCO as well.

Deployment & Ongoing OpEx

Licensing Options

When setting up a virtual desktop infrastructure (VDI), one of the significant upfront costs is software and hardware licenses. However, careful planning can help streamline these expenses. The choice between Windows or Linux operating systems depends on your use case. Linux, being open-source, is a cost-effective option for scenarios like supermarkets or retail environments. However, Windows licenses may be preferred if your applications or users require Microsoft-specific technologies or familiarity.

VMware and Citrix solutions require you to purchase the VDA license, which can be optimized by going for the 3-year subscriptions. Neverinstall allows you to opt for the Windows E3 or E5 option without the RDS Cal license.

VDI License

Citrix license stands comparatively higher at $25/user/month while VMware and Neverinstall have a comparable rate at $5-$20 with different tiers. It's a monthly cost and can be altered according to your compute needs.

Storage Costs

To calculate the annual storage costs for 100 users with 128GB/user, we need to find the total storage requirement and then estimate the costs based on typical storage pricing.

Given:

• Number of users: 100, 150 and 225 assuming a 50% growth in headcount every year.
• Storage per user: 128GB (0.128TB)

The annual storage costs will depend on the type of storage solution you choose (e.g., SDD, HDD, etc.) and the associated pricing model.

For example, if you opt for cloud storage at a rate of $0.02 per GB per month, the annual costs would be:

100 users × 0.128TB/users × 1024GB/TB × $0.02/GB × 12 months = $3,146

and so on for 150 and 225 users in the next few years.

Energy Costs

The energy consumption for average usage of 22 days a month, 8 hours a day, at $0.17/KWHr, not considering perpetually running machines, results in a cost of $50,261 in the first year.

In contrast, for Neverinstall, the cost runs up to $25,295 due to the optimized logic associated with their servers and backend.

Labor Costs

On average between highly and moderately skilled IT technicians required to run your IT set up, the cost per hour is considered to be $40.
