Reliable web hosting is critical for small and medium-sized enterprises (SMEs) to keep their websites online. As businesses grow, the cheapest option – shared hosting – can lead to traffic and security issues. Virtual private server (VPS) hosting offers a middle ground between shared and managed hosting, providing dedicated resources within a physical server.
VPS hosting uses virtualisation to partition a physical server into separate virtual machines, each with its own dedicated resources. Richard Ford, chief technology officer at Integrity360, says virtualisation has been a mainstay of data centres since the early 2000s, and modern compute power allows many virtual servers to run on a single physical host. Unlike cloud hosting, which is distributed across a network, VPS hosting typically provides more stable and predictable performance.
Experts say VPS hosting is better for growing businesses compared with shared hosting. Tom Vazdar, professor of cybersecurity at OPIT, explains that shared hosting puts a site on a server with potentially hundreds of others, all drawing from the same pool of power and memory. A traffic surge from one site can slow down neighbours, and a compromised site can affect others in the same environment. A VPS removes both problems by giving each user their own resources and proper isolation.
The cost of VPS hosting ranges from £20 to £50 per month, compared with £5 to £15 for shared hosting. While not the cheapest, it offers more flexibility and control without the expense of a dedicated server. Luis Corrons, security evangelist at Gen, notes that VPS hosting sits in the middle ground, offering better isolation and configuration options than shared hosting.
VPS is sometimes confused with VPN, but they are very different. Corrons clarifies that a VPN is a privacy and networking tool that protects or re-routes network traffic, whereas a VPS is infrastructure used to run websites, services, or applications.
In terms of security, VPS hosting is generally considered safe, particularly compared with shared hosting. Roy Shelton of Connectus Business Solutions says that because the environment is isolated, other users cannot directly impact your server. However, security still depends on proper configuration, regular updates, and effective management. Vazdar warns that an unmanaged VPS gives you root access and makes you responsible for your own security, so it is essential to configure strong security settings and choose a provider with solid security credentials.
