VPN vs VPS
As you can tell by now, VPS and VPN and two very different things. However, it is interesting that they can be used together effectively. For instance, if you are a VPS hosting user, you can use a VPN service while connecting to and using your VPS account.
By doing this, you are increasing the security of your website by taking advantage of the properties of a VPN. Take for example if you are transferring your website files and database. Using a VPN means the data in transit gets encrypted.
Something a little more unique is the fact that since VPS hosting is so configurable, you can actually build your own VPN service using it. Of course, this will be much more limited in use compared to a commercial VPN service, but it will work for some purposes.
Conclusion
The tongue twister combination of VPS and VPN can be a little confusing on the surface, but gets clearer as you understand them. Each of these services have their own uses, but can be combined for better overall security.
VPS hosting can also be used to build VPN services, but this is typically of very limited use compared to full-service VPN plans offered commercially. For web hosting though, you will definitely need a hosting plan of some sort – VPS or otherwise.
