This question almost always arrives the same way: the office server is five or six years old, warranty is expiring, and someone has quoted five figures to replace it. Suddenly “should we move to the cloud?” stops being a conference topic and becomes a purchasing decision with a deadline.
The honest answer — the one Indigo IT gives clients even when it means selling less hardware — is that most office-based SMEs in 2026 no longer need an on-premise server, but a meaningful minority genuinely still do, and pretending otherwise causes expensive mistakes in both directions. Here’s the framework for working out which side you’re on.
What your server actually does (the question nobody asks)
Before deciding where your server should live, list what it does. For most SMEs the answer is some combination of: file storage, email (if you’re still running Exchange on-premise), user sign-in and permissions (Active Directory), one or two line-of-business applications, and printing. The cloud question is really five smaller questions — because each of those jobs migrates differently, and the last one on your list usually decides everything.
The jobs that have already left the building
- Email — If email still runs on a server in your comms cupboard, this decision is made. Microsoft 365 does it better, cheaper and more securely for a business your size, and on-premise Exchange has become a security liability that insurers and auditors increasingly flag.
- Files — SharePoint and OneDrive replace the traditional file server for the large majority of office businesses — with the bonus that files work properly for hybrid and remote staff instead of through a temperamental VPN. The exceptions are below.
- Sign-in and identity — Microsoft Entra ID (with Intune managing the devices) replaces on-premise Active Directory for most SMEs, and does it with modern security — conditional access, MFA enforcement — that a local domain controller can’t match.
The cases where a server still earns its keep
- Line-of-business applications — Some industry applications — certain manufacturing, engineering, logistics and practice-management systems — still require a local SQL database or Windows server, or run poorly hosted remotely. If your critical application is one of these, your decision is set by the software vendor’s roadmap, not by cloud enthusiasm. Ask the vendor the blunt question: what does your cloud path look like, and when?
- Very large files — CAD, video, large design files and high-volume scanning can make cloud file storage painful on ordinary connections. Engineering and creative firms often keep local storage for working files — sometimes as a hybrid, syncing to the cloud for protection while working locally for speed.
- Connectivity limits — Cloud-first assumes decent connectivity. If your premises’ internet is genuinely poor and can’t be economically upgraded — rarer than it was, but real for some sites — a local server remains a rational choice, and improving connectivity may be the better investment than either option.
- Specific compliance — A minority of compliance regimes and customer contracts (some defence supply-chain work among them) impose data-location or air-gap requirements that make local infrastructure simpler to evidence. If this is you, you already know.
The money, done honestly
A capable SME server with warranty, licensing, backup infrastructure and installation typically lands between £8,000 and £15,000 up front, plus ongoing power, maintenance and eventual replacement — a five-year cycle that never ends. Cloud equivalents move that to a monthly per-user cost with no replacement cliff. Run both as five-year totals and cloud usually — not always — wins for office workloads, especially once you price the risks: a server is a single point of failure sitting in a building that can flood, lose power or be burgled.
Two costs cloud advocates gloss over, and Indigo IT prices into every migration plan: the migration itself (data moves, application reconfiguration, staff disruption if done badly) and connectivity — a business going cloud-first should usually upgrade its internet and add a backup line, which belongs in the comparison.
How to decide, in one afternoon
List your server’s jobs. Ask your line-of-business vendors about their cloud path. Check your connectivity headroom. Then total five-year costs for three options: replace the server, go fully cloud, or run the pragmatic hybrid (cloud for email, files and identity; a smaller local box only for the stubborn application). That hybrid is where a large share of real SMEs land for a transition period, and there’s no shame in it — it beats forcing an application into a cloud it isn’t ready for.
This is a decision Indigo IT works through with businesses across Surrey, Hampshire and Berkshire most months, usually starting from exactly the ageing-server moment you may be in now. If you’d like the analysis done properly — jobs, vendor roadmaps, connectivity, five-year costs — our IT consultancy team will give you the numbers and a recommendation you can hold us to, whichever side of the fence it lands on.
Frequently asked questions
Is the cloud more secure than our server?
For a typical SME, yes — Microsoft’s data centres are patched, monitored and physically secured beyond anything an SME can economically match, and modern identity controls (MFA, conditional access) come built in. But cloud security is configuration-dependent: a badly set-up tenancy is its own risk, which is why migration should include a security baseline, not just a data move.
What happens to our server during a migration?
It keeps running until the cloud services are proven, then is retired — typically a phased handover over some weeks, not a weekend cliff-edge. Staff disruption in a well-run migration is minimal: the biggest change most users notice is where their files live.
Our server works fine. Why change anything?
If it’s mid-life, don’t — the economics favour migrating at natural replacement points, not scrapping working kit. Use the time to prepare: move email and files first if they’re still local, so that when the hardware decision arrives it’s small rather than existential.
