A Virtual Private Server Hosting and a Shared Hosting differs in every aspect of resource sharing! Let’s see the stark difference between the two,
Resource Availability: You share a server with many other users in a shared hosting whereas, in VPS, a dedicated virtual machine with a pre-allocated resource cap is available. In general, a website hosted in VPS shows more performance than in Shared hosting.
Security: Sharing a website with others may pose several threats. But in VPS, each website is private from other users and your website will be completely secure.
Scalability: A VPS is much more scalable when compared to Shared Hosting, and perfect for a website which requires continuous growth.
Though other factors like Pricing and Server maintenance are effective in Shared Hosting, those requirements alone are not enough to run your website in a seamless manner.
Thus said, a VPS hosting is far better than a Shared Hosting!
