With VPS you get root access so you can set the privacy , security rules and other stuff as required for your needs. But in shared you will not be able to access all this root access things.
When you are talking about VPS you need to understand the gist of it. VPS is approximately the same as shared hosting (means you are sharing physical server with others). If you are interested in dedicated solutions - better have a look and check dedicated servers of course.
Benefits of a Dedicated Server VS VPS and Shared Hosting Load times are dramatically decreased since resources are dedicated to your specific server and business Reliability increases since you are not sharing your server with others Security risks are reduced With multiple configurations, can fit any requirement
VPS vs Shared Hosting Shared Hosting means multiple websites share a web server. With VPS Hosting you technically still share a server however you get a dedicated slice of it that's just for you. It is also known as a virtual dedicated server. Shared Hosting is cheap because it does not many features. VPS hosting is expensive because it comes with more speed, more bandwidth, and greater security. If you plan to start a personal blog, basic website with static content then go for shared hosting. If your business is well established or you plan to create an online store, e-commerce website, any dynamic web application then VPS hosting is the answer. Hope that helps!
