Shared Hosting.
The sort of web hosting service you have is known as Shared Hosting, regardless of whether you have the Unlimited Hosting plan or the Free Web Hosting subscription. A web server's storage space is shared by users of a shared hosting plan. Web hosting providers can charge less for these services since the cost of the web hosting servers is shared by all users.
The users who are on the same shared server, nevertheless, have access to all the files. All users on the shared server are impacted if one user commits a scripting mistake. Therefore, customers who subscribe to shared hosting services are not allowed to run their own applications in order to reduce the likelihood of this happening.
VPS Hosting.
VPSs (Virtual Private Servers) are for people who need to run specialised programmes on a tight budget. In essence, VPS users continue to share the server with other users but are given individual access to the computers. In other words, the server's other users have no impact on your files or hosted websites, and each VPS user would be guaranteed resources (e.g. Guaranteed 256MB ECC RAM of the web server). More security and performance may be offered by this service. The average monthly cost for a VPS is about $20 USD.
Which One To Choose?
For seasoned programmers and/or companies with a webmaster, VPS hosting is highly advised. The assigned servers can be completely controlled by VPS users. For users on a tight budget, shared hosting is perfect.
