VPS or virtual private servers are comparatively more reliable, secure as well as flexible than
shared hosting. You ideally get more resources by paying a little higher when you go for VPS. Only that you need to install a little plugins and extensions to go smoothly with virtual private servers. On the other hand, a shared hosting will not help you with all this. It hardly manages all your extensions and plugins without effecting the performance and speed of the accounts on the server.
A VPS is obviously faster because of the dedicated attribute it carries along. Entire resources are dedicated to work for your business only. If another website is hosted on the same server and confronts any error, your VPS remains untouched and this is the quality of a VPS. While a shared hosting caters to multiple sites at one go. Any effect on the
web server would mean that your site is going to be effected certainly. In case of wrong programming, infinite loops and exploitation of resources, all the websites get effected. This is the reason of the lower speed observed in case of shared hosting since the resources available for them is lesser. When you
buy VPS plan, you do share the server still but the features and technical attributes are similar to
dedicated servers.
