With VPS Hosting You Have Full Root Access
You have full access to all of the elements that make your web sites yours. You have operational separation and full authority to set up scripts, manipulate the configurations of any and all of these and you are not influenced by anything that anyone else is doing on their websites. This is very important to you as a webmaster.
This gives you the ability to adapt the web server with great scalability. The VPS hosting company will keep track of the needs that you have and make suggestions as to when you need to enlarge your disc space.
Not needing to share a server with other, possibly less qualified users, will keep you and yours very safe. The first time that you do this, you will notice the difference. The exclusivity is the thing that helps keep you on track.
The ability to upload, download and re-boot as needed and also the updates of previously uploaded material will be the icing on the cake as far as flexibility is concerned.
