The difference between a virtual private server (VPS) and a dedicated server is that a VPS is an emulation of a computer that lives within a parent server and shares resources with other virtual servers. A Dedicated Server is a stand-alone, physical server that does not share resources. Because a VPS shares finite resources with other virtual instances on the parent, overuse of a VPS can lead to less than optimal performance for any resource-intensive applications, which is why dedicated servers often outperform virtual private servers.
VPS and dedicated servers share several overlapping qualities, but most importantly, the dedicated servers provide greater security, extra customization options, and higher availability and uptime. With more granular controls, you are free to customize hardware components like CPU, disk space, and RAM as well as the use of a unique operating system. these allow dedicated servers increased performance for highly trafficked sites. When uptime and performance are critical to your business, dedicated servers are unrivaled in performance and value.
