Shared vs VPS vs Dedicated Hosting: Which Does Your Business Need?
Shared, VPS, dedicated — every hosting company sells all three, and the sales pages rarely explain what actually changes between them. We host business sites ourselves, and the honest answer is often the cheapest tier. What follows is the plain-English version we give businesses across Edinburgh and the Lothians when they ask which one they need.
What you're actually buying
All three are the same thing underneath: a computer in a data centre running your website, connected to the internet. What changes is how much of that computer is yours, how much control you have, and who is responsible when something breaks. Price follows those three things, not the other way round.
Shared hosting: many sites, one machine
On shared hosting your site sits alongside many others on the same server, all drawing from one pool of processor, memory and disk. The host manages the machine, patches the software and gives you a control panel. For a brochure site or small shop, that is often enough.
- Noisy neighbours. Another customer's badly written site or traffic spike can slow yours down, with no visibility into why.
- Hard resource limits. Expect caps on memory, processes, database connections and how long a script may run. Hit one and pages fail rather than merely slow.
- Very little control. You take the software versions the host chooses. If you need a specific PHP extension or a background process, you're often stuck.
VPS: your own slice, your own responsibility
A virtual private server carves one physical machine into several isolated virtual ones. You get a guaranteed allocation of memory and processor, your own operating system and root access. Neighbours can no longer eat your memory, and you install what you like.
The trade is that the operating system is now yours to look after. Security updates, firewall rules, backups, certificate renewals, monitoring — somebody has to do all of it, and on an unmanaged VPS that somebody is you. A neglected VPS is less safe than decent shared hosting, where the host at least patches the underlying system.
Dedicated: the whole machine
A dedicated server is a physical box used only by you. No virtualisation overhead, no sharing, full control of the hardware. It suits sustained heavy load, large databases, or contracts requiring that nothing else runs on the same equipment. For most small businesses it is more machine than the workload justifies — a well-sized VPS handles far more traffic than people expect.
Managed versus unmanaged is the real question
Ask any host, ourselves included, exactly where responsibility stops. "Managed" is not a regulated word: some hosts patch the operating system and nothing above it, others cover your application, backups and monitoring too. Get it in writing.
- Operating system updates. Who applies them, and how soon after release?
- Backups. Who takes them, how far back do they reach, and — the part people skip — has anyone ever tested a restore?
- Out-of-hours cover. Who answers at 2am, and is that included or charged separately?
- Leaving. Can you export everything yourself, without their help?
The cost shape, not just the cost
Shared hosting is a small predictable monthly figure. A VPS costs more, and the honest total includes whoever administers it — either your time or someone you pay. Dedicated costs more again, usually on a longer commitment. A cheap unmanaged VPS that nobody maintains is the most expensive of the three once it goes wrong — the same reasoning as any IT budget: count the ongoing effort, not just the invoice.
Choosing without guessing
Start from the workload. If your site is mostly pages and images with modest traffic, shared hosting is not a compromise. If it is an application with real users, background jobs or a growing database, move to a VPS and decide deliberately who administers it. Go dedicated only once you have measured the need. Whichever you pick, keep your own copy of the data — the same principle behind a proper business backup strategy and a written disaster recovery plan.
We build and host business websites
Website design, web hosting and email hosting sit alongside our business IT support and managed IT services. That might be a new site built and hosted on the right tier, the WordPress site nobody has updated in a year, mailboxes moved onto proper business email hosting, or a Microsoft 365 move planned and run. We're in Wishaw and work across Edinburgh, Livingston and Musselburgh. Tell us what the site has to do and you'll have a clear quote before any work.
