Virtual Private Server (VPS) vs Shared Hosting
All of the websites on a shared server share the operating system and resources (such as CPU time allowance and delays, bandwidth, RAM memory). If your neighbours have problems with their sites this can temporarily slow down the server’s performance and therefore your website’s performance. On the other hand a Virtual Private Server provides a partitioned environment. Every partition has a separate operating system installed on it and a guaranteed share of hardware resources (as above). Whilst the server does have multiple operating systems and partitions, each of the partitions behaves the same as a dedicated server; but at a much lower cost to you.
Dedicated servers, because of the higher level of control they offer growing websites, are often considered as an option. The cost can be difficult to justify despite the attraction of added control. The same functionality of a dedicated server is provided by a VPS Plan but at a lower cost. Using a VPS Plan, Webmasters can use many of the self-management tools such as the ability to start, stop, and reboot a server without technical support from the web hosting team.
