Virtual Private Server hosting, also known as VPS hosting, is a website hosting environment that allows resources such as RAM and CPU to be allocated to your account. This is achieved by simulating a dedicated server and dividing the resources among the users on that server.

Users guarantee the resources on their VPS web hosting account. This means that your account will always be allocated the exact amount of RAM, CPU and disk space you've chosen regardless of what other users do on the server. This allows for greater stability and performance of your website. You also do not share the operating system with any other users, which provides better security for your website files.

All shared hosting users share the resources on the server on their websites. There is no guarantee of RAM or CPU with shared hosting. Shared hosting also does not provide full root access to the server, unlike a VPS package where users are given full root access to execute commands and make configuration changes to their hosting environment.
