VPS hosting gives you high performance with an isolated environment where the CPU, RAM and storage is 100% dedicated and not shared with any other websites or apps. That, compared to shared hosting, results in higher performance and security along with more flexibility and control over the server.
VPS hosting also offers higher resources and bandwidth/traffic than shared hosting, which means faster load times and unlimited traffic. A VPS allows the admin more control over security hardening and is less vulnerable to hackers in comparison to shared hosting. With shared hosting, if a site gets hacked there’s a greater chance that other websites on the server will also be compromised. Conversely, due to virtual isolation, a hacked VPS on the same hardware, won’t affect surrounding VPS environments.
And with root access, there are no restrictions on the applications you install; you can access and edit the system files, settings and server logons.
