Virtual Private Server (VPS) hosting is where multiple websites use the same server, but have their own set resource limits on things like RAM and bandwidth. It also uses what’s known as a hypervisor (specialist software) to borrow resources from the other sites on the server if you’re maxed out and others aren’t using their full allocation. Generally, VPS hosting is suited to small business websites, or large personal sites that need decent resource limits. No one wants the pain of slow loading speeds on their site, or worse still, to have their site constantly crashing. That’s why VPS hosting works well – it’s flexible in handling surges of traffic, and isn’t too expensive.
VPS clients get a share of a physical server for a number of hardware resources they’ve paid for, and multiple clients often share one physical host machine. From the client’s perspective a VPS barely differs from a dedicated server with a comparable low to mid-range configuration, but thanks to the virtualization layer, we can maintain a uniform range of host hardware while offering multiple different virtual server configurations, which then, in turn, translates to a wider range of server options and lower prices than with dedicated servers.
Dedicated hosting is the big cheese of the web hosting space. You don’t simply get a slice of stilton or a chunk of cheddar – you get the whole wheel of wensleydale. In essence, you have an entire server to yourself. You’re in total control from the get-go, and can choose your own resource limits. Dedicated hosting tends to be for medium to big business sites, but if you’re ambitious, you can save time and hassle in the long-run by signing up to a dedicated plan (safe in the knowledge your site will grow to that level).
Dedicated servers offer close to metal implementation with little overhead, and they’ve been traditionally the go-to-solution for high performance demanding tasks. As the name implies, each server is dedicated privately to one client. The customer receives access to a physical server with the agreed upon hardware specifications, processing and storage, all in one unit.
