Ryan Mangan
Founder & CTO of Systech IT Solutions, Microsoft MVP, Chartered Fellow of the BCS, and author of the bestselling Mastering Azure Virtual Desktop.

Ryan has spent nearly two decades in end-user computing, cloud and modern application delivery, helping organisations adopt Microsoft technology pragmatically, without the complexity or cost that usually comes with it. He is the author of the bestselling Mastering Azure Virtual Desktop, published across multiple editions, with articles in the British Computer Society's IT Now and Computer Weekly on legacy applications, sustainable computing and AI reliability.
A recognised voice in the industry, Ryan advises technology vendors and enterprise IT teams on their cloud, workspace and AI strategies, and brings that same senior-level thinking to every Systech engagement.
Why AVD, Windows 365, and Systech
Ryan started in end-user computing at a time when “virtual desktop” usually meant something clunky, expensive and reserved for enterprises with a dedicated infrastructure team behind it. What kept him in it was watching Azure Virtual Desktop, and later Windows 365, make that same capability genuinely usable for businesses without a platform team of their own. That is the specialism he has built the last chunk of his career around, and it is the reason Microsoft recognised him as an MVP for Azure Virtual Desktop and Windows 365 specifically, rather than a broader Azure or Microsoft 365 category.
Writing the book
Writing Mastering Azure Virtual Desktop came out of the same instinct. Most of what was being published on AVD at the time was either vendor marketing or documentation that assumed you had already made every decision correctly. He wanted a book that walked through the decisions themselves: licensing, sizing, image management, autoscaling, the things that actually determine whether a rollout is still stable six months in. Packt published it across two editions, the second brought up to date as the platform, and Windows 365 alongside it, both moved on.
Chartered Fellowship, and founding Systech
Being made a Chartered Fellow of the BCS, the Chartered Institute for IT, sits alongside that the same way: it is a peer-assessed recognition of experience and contribution to the profession, not a vendor badge. Ryan founded Systech IT Solutions in 2013 on the same premise the book and the MVP work both come back to, that most businesses do not need enterprise complexity to get enterprise-grade outcomes. They need a team that has actually done the specific thing they are trying to do, and can tell them honestly what it takes.
What the work looks like now
That is still what most of his day-to-day work looks like, whether it is a Windows 365 migration, an Azure cost review, or helping a client work out whether Copilot is actually ready to switch on. The technology changes faster than most businesses can keep pace with; the value of nearly two decades in this specific corner of it is knowing which changes matter and which are just noise.
If you are weighing a decision rather than looking for a supplier, how our consultancy works sets out what an engagement actually produces, what it costs to find out, and the cases where the honest answer is that you do not need us.

Open technical reference
Ryan maintains a public MSIX App Attach reference wiki on GitHub: working notes on CIMFS and VHDX image handling, code-signing certificates, Azure Files requirements, host pool assignment and the event-log traces that actually explain a failed package. It is the same material behind our application packaging and Windows 365 and AVD work.
He also writes at Democratising Clouds, is CEO of EfficientEther, speaks at industry events (speaking history), and has been published in the British Computer Society's IT Now and Computer Weekly on legacy applications, sustainable computing and AI reliability.
