The type of web hosting service you have is called Shared Hosting. Whether you’ve subscribed to free web hosting or the Unlimited Hosting plan. With a shared hosting plan, you share storage with other users on a web server.
Because all users share the cost of the web hosting servers, web hosting providers can offer more affordable prices for such services.
All the files are, however, exposed to users who are on the same shared server.
If scripting errors are made by any of the users, all users on the shared server are affected.
Therefore, to reduce the likelihood of this occurrence, users who subscribe to Shared Hosting services are not allowed to run their own programs.
Virtual Private Servers (VPS) are for those who, on a low budget, need to run customized programs.
Basically, VPS users still share the server with other users, but separate computer functions are given to them. In other words, your files and hosted websites are not affected by other server users, and the server resources of each VPS user are guaranteed.
WHICH SHOULD YOU CHOOSE, SHARED HOSTING OR VPS HOSTING?
For experienced programmers and/or companies that have a webmaster, VPS hosting is strongly recommended.
Users of the VPS can have full control of the servers assigned. For users that are on a limited budget, shared hosting is ideal.
