Ecommerce hosting explained

Hosting is one of those parts of running an online shop that most business owners think about once and then forget about - until something goes wrong. A slow shop, an outage at a critical moment, a security breach - these are usually hosting problems or hosting-adjacent problems.

This guide explains what hosting is in plain terms, what the different types mean for a small ecommerce business, and what to look for - or ask for - when it's part of a project conversation.

What hosting actually is

When a customer types your shop's URL into a browser, their browser sends a request to a server somewhere asking for your shop's files. Hosting is the server - the computer, permanently connected to the internet, that stores those files and delivers them on request.

Every website and online shop has hosting. The quality of that hosting affects:

• Speed - how quickly pages load for customers
• Reliability - how often the shop is available (uptime)
• Security - how well the server is protected from attacks
• Scalability - whether the server can handle traffic spikes (a PR mention, a sale, a viral social post)

Types of hosting

Shared hosting is the cheapest option. Multiple websites share the same physical server. If another site on your server gets a traffic spike or is compromised, it can affect your shop. For informational websites, shared hosting is often fine. For an online shop handling customer payment data, it's generally too risky and too slow.

VPS (Virtual Private Server) hosting gives you a dedicated portion of a server's resources. You're still on shared hardware, but your allocated memory and processing power can't be used by anyone else. This is the appropriate starting point for most small ecommerce shops - fast enough, reliable enough, and reasonably priced.

Dedicated server hosting gives you an entire physical server to yourself. Faster and more configurable, but significantly more expensive and more than most small shops need.

Managed hosting is any arrangement where a person or company handles the server configuration, security patches, backups, and ongoing maintenance for you. This is often what a designer or studio provides when they say hosting is included in the package. You're not buying a server - you're buying the expertise and ongoing management of one.

Platform hosting (Shopify, Wix, Squarespace) is included in the monthly fee. You don't manage the server - the platform does. This removes the technical burden but means you're entirely dependent on the platform's infrastructure and have no ability to optimise it independently.

What matters specifically for ecommerce

Speed. Page speed affects conversion rates directly. Studies consistently show that a one-second increase in load time reduces conversions by several percent. It also affects Google rankings - speed is a ranking factor. A hosting environment that serves pages in under one second is meaningfully better than one that takes three.

SSL certificate. This is the HTTPS padlock in a browser's address bar. It encrypts data between your shop and your customers' browsers. It is non-negotiable for an online shop - browsers flag non-HTTPS sites as insecure, and customers won't complete purchases on them. Any reputable hosting provider includes SSL certificates, often free via Let's Encrypt.

Uptime. "99.9% uptime" sounds like a marketing claim, but it has real meaning. 99.9% uptime means roughly 8 hours of downtime per year. 99.99% means under an hour. A shop that's down on Christmas Eve or during a promotional email send loses real money. Ask what uptime guarantees apply and what the process is if the shop goes down.

Backups. Automated daily backups mean that if something goes wrong - a botched update, a malware incident, a human error - you have a restore point from yesterday rather than having to rebuild from scratch. This should be standard. If a hosting package doesn't include backups, either add them or find different hosting.

Who manages it - and why it matters

For most small business owners, server management is not something they want to think about. Keeping a server secure and up to date requires ongoing attention - security patches, software updates, monitoring. The question isn't just "what hosting do I need?" but "who is going to manage it?"

Options:

• Your designer manages it - most common with bespoke shops. The designer hosts the shop on infrastructure they manage, and the hosting fee covers that management. You don't think about the server.
• You manage it yourself - possible if you have technical knowledge, but requires genuine engagement with server security and updates. Not appropriate for most small business owners.
• A managed hosting provider - companies like Kinsta, WP Engine, or similar who handle server management for a fee. Reliable but adds cost.
• Platform hosting - if you're on Shopify, hosting management is entirely off your plate. The trade-off is everything else that comes with being on a platform.

Domain names and hosting - not the same thing

A common source of confusion: your domain name (yourbusiness.co.uk) and your hosting are separate things from separate providers, though they need to be connected to each other.

The domain is registered with a domain registrar (GoDaddy, Namecheap, 123-reg, etc.). The hosting is on a server. DNS records in the domain's settings point visitors from the domain to the correct server.

This matters because: you should own your domain in your own name, with your own login. Not your designer's. If the relationship ends, you need to be able to point the domain wherever you choose. A designer who registers your domain in their own name - intentionally or carelessly - has leverage over your business that you should never give anyone.
