If there's a box humming away in a cupboard at your office, and someone has recently mentioned that it's getting old, you're not alone. Many small businesses, schools and charities reach a point where their on-site server needs replacing, and the obvious question comes up: should we buy another one, or is it time to move to the cloud?
The honest answer is that it depends on what your server actually does. For some organisations, the cloud is a clear win. For others, a mix of cloud and on-site works better. This guide walks through the options in plain English so you can have a sensible conversation about what's right for you.
First, work out what your server is doing
Before comparing options, it helps to list what the server is responsible for. In a typical small office, it might be handling some or all of the following:
- Storing shared files and folders
- Email (older setups sometimes still run Exchange on-site)
- User logins and passwords for office computers
- Running a line-of-business application, such as accounts, practice management or a school MIS
- Printing and network services
- Backups of other machines
Each of these has a different cloud alternative, and some are much easier to move than others. Files and email are usually straightforward. Specialist software is where the real decisions lie.
The main options
Option 1: Microsoft 365 for files, email and logins
For many small organisations, Microsoft 365 can replace most of what the server does. Email moves to Exchange Online, shared files move to SharePoint and Teams, personal files go into OneDrive, and staff logins can be managed through Microsoft Entra ID (formerly Azure AD), with devices managed through Intune.
The big advantages are that there's no hardware to maintain, staff can work securely from anywhere, and Microsoft looks after the underlying infrastructure. You pay a monthly per-user licence rather than a large upfront cost every five years or so.
It's worth knowing that SharePoint isn't simply a mapped drive in the sky. Very large files, deeply nested folder structures or certain types of data (big CAD files or databases, for example) may need some planning. A good migration will tidy up your folder structure and permissions rather than just copying everything across.
Option 2: A server in Microsoft Azure
If you rely on software that needs a proper Windows server, such as an older accounts package or a database, you can run that server in Microsoft Azure instead of your cupboard. It behaves much like your current server, but lives in a Microsoft data centre.
Azure is flexible and resilient, and it's well suited to businesses already using Microsoft 365. Costs are based on usage, so getting the sizing right matters. An oversized virtual server left running around the clock can cost more than expected, while a well-planned one can be very good value.
Option 3: A hosted virtual private server or dedicated server
Another route is a hosted server from a provider, either a virtual private server (a share of a powerful machine) or a dedicated server (a whole machine just for you). These tend to offer more predictable monthly costs than pay-as-you-go cloud, which some organisations prefer for budgeting. They're a practical choice for running specific applications or remote desktop services.
Option 4: Hybrid, or replacing the server on-site
Sometimes keeping something on-site still makes sense. Examples include very large files that need fast local access, equipment that must connect to a local machine, or a poor internet connection. In those cases, a smaller, newer server combined with Microsoft 365 for email and documents can give you the best of both. Buying a like-for-like replacement is still a valid choice, as long as it's a deliberate one.
Things to check before you decide
- Your internet connection: cloud services depend on it. A reliable business broadband line, ideally with a backup connection, is important.
- Your software: ask your software suppliers whether they offer a cloud version or support hosting in Azure. Many now do.
- Licensing: some applications have specific licensing rules for cloud hosting.
- Backup: Microsoft keeps your data available, but it's still sensible to have a separate cloud backup of Microsoft 365 and any cloud servers.
- Security: moving to the cloud is a good moment to switch on multi-factor authentication and review who has access to what.
- Data rules: schools, charities and care providers handling sensitive personal data should check where data is stored and how it's protected. UK data centres are available for most services.
Comparing costs fairly
It's easy to compare a monthly cloud bill against nothing, because the old server is already paid for. A fairer comparison includes the cost of new hardware, Windows Server licences, warranty, electricity, backup, and the time spent maintaining and patching it, spread over its likely life. Factor in the business cost of downtime if an ageing server fails, too. Sometimes the cloud works out cheaper, sometimes it doesn't, but it's usually more predictable.
Timing matters
The worst time to plan a migration is the day after your server fails. If your server is more than a few years old, out of warranty, or running a version of Windows Server that's nearing end of support, it's worth starting the conversation now while you have time to plan, test and move over calmly, often with very little disruption to staff.
