In-house VDI vs. DaaS: Management
For virtual desktop management and support, we’ve already covered the platform-side from a personnel and infrastructure perspective; however, when it comes to desktop management, in my opinion, the industry has historically made a mistake in that it tends to see both VDI and DaaS as solutions that will eliminate the administrative burden of managing desktops.
Frankly, that’s incorrect. Either solution can greatly reduce the administrative burden, but neither truly does away with it.
With both solutions, much of the administrative burden is shifted from managing desktops to managing images/templates, and many IT teams inadvertently make their jobs more complex by limiting their ability to utilize automation tools to assist with things like patching and antivirus management when deploying dynamic desktop environments (Note: we’ll address this more in a future blog post comparing and contrasting Static vs Dynamic DaaS solutions).
Having said all of this, there is a lot to be gained through streamlining either a VDI or DaaS solution to use as few images as possible; I like to refer to this as ‘simplification-through-standardization’ – the more you can provide a consistent user experience with fewer variables, the easier that solution is to support and manage.
In this case, VDI and DaaS are neck-and-neck with neither having much of a practical advantage over the other, but one of the ancillary benefits of a DaaS solution is in working with a provider who has a myriad of experience having worked with clients, designing these solutions. The right partner will share the lessons-learned and guide your business based on what they have seen clients do both successfully and unsuccessfully.
In-house VDI vs. DaaS: Costs
In terms of virtual desktop budgets, I have to caveat my thoughts by saying that, historically, I’m not a ‘financials’ guy any more than I have ever needed to be, so we’re probably not going to get into much nuance when it comes to tax deductions, organizational budgeting impacts, and expense amortization. You will have a far better idea of your organization’s preference for capital expenditure (CAPEX) vs operational expenditure (OPEX) and reasons therein.
The important thing to note for the purposes of our discussion is that CAPEX-leaning organizations, who are more open to making the significant investment in the required infrastructure, would seem to be a better fit for VDI, whereas OPEX-leaning organizations would be a much more natural fit for the subscription-based approach of DaaS.
What about when we look at the technology-side of CAPEX vs OPEX, though? Are there any differences there?
This is where I would like to introduce what I refer to as ‘The Bucket Problem.’ I have three buckets, each of which can hold twenty gallons. Any amount up to sixty gallons, total, I can easily accommodate within those buckets; whether that’s three buckets with ten gallons each, or two with fifteen each, and one with seven. I am completely fine as long as I stay within the sixty gallons that I have allotted to myself.
What happens when I get to gallon number 61, though? Now, I have a decision to make. Do I run out and buy another twenty-gallon bucket knowing that I’m not going to get close to that eighty-gallon-mark for a long time, so I’m buying a lot of extra capacity that I don’t immediately need, or do I just get a five-gallon bucket to kick the problem down the road a while but which leaves me with an asymmetrical and internally inconsistent solution?
This is the exact problem businesses face with an internal VDI, CAPEX-driven model. Once you start to get near the capacity of available desktops and begin to start planning for growth, you need to determine how you will grow the environment. This also makes locking-in an exact price per user difficult, because, to our earlier example, that 61st gallon of water is now costing you as much as gallons forty-one through sixty are as a whole.
One of the primary benefits of a DaaS platform with a subscription model is that every user has the same cost which remains consistent as the platform grows. This Predictable Cost Model makes growth, especially for Merger & Acquisition-driven companies, much easier than with an in-house VDI solution.
Another virtual desktop budget consideration is whether or not everyone in your company needs DaaS or VDI. New solutions, like Evolve IP’s Workspaces, can help furthrer reduce costs by providing a single virtual desktop platform that allows IT to deliver DaaS to only those users who need a cloud desktop, while the rest of the business’ employees can access SaaS and legacy line-of-business applications via SSO and MFA. One platform, completely secure, and everything runs the same way on laptops, desktops, tablets and mobile devices.
So, when it comes to VDI vs. DaaS, which is the right fit for your organization? Well… that’s not an answer that anyone else can give you. My personal suggestion would be to make sure that you give both equal consideration and be sure to run a Total Cost of Ownership comparison as part of your evaluation process. That will give a firm grasp of all of the financial considerations of both solutions.
When comparing TCO for a do-it-yourself VDI solution to a subscription-based cloud DaaS solution be sure to include easily neglected elements like personnel headcount, capacity, training, licensing, datacenter costs, additional external bandwidth, etc. If you don’t include these pieces upfront, those costs will end up surprising you later.
In-house VDI vs. DaaS: Providers
Also, try to find a way to quantify the intangibles such as the benefit of working with a provider who has experience (shameless plug – Evolve IP is VMware’s largest DaaS provider in the world and we’ve been in every DaaS Gartner Market Guide since inception) and whether your organization may be able to benefit from ancillary services like additional management or support from a provider which may have the added benefit of additional discounts or economy of scale savings.
Good health and best wishes, and best of luck navigating the waters of selecting and providing the most robust, secure, and scalable Work Anywhere solutions called for in our current times! We, at Evolve IP, are here to help however we can!
