VDS/VPS offer several advantages over dedicated servers, including lower cost and potentially higher performance. Additionally, they allow for easy scalability, with the ability to add capacity in the form of additional RAM, processor cores, or hard disk space.

However, there are also some downsides to using a VDS or VPS server, including the fact that virtual servers share a disk system and communication channel. As a result, if one user misuses resources or interferes with other clients, it can impact the entire system.

I believe that the need for administration in the case of a virtual server is a much more significant disadvantage for the vast majority of users. Knowledge is a valuable and expensive resource that takes time and experience and can seriously compete with the "use of common resources".

There is a common misconception among inexperienced users that VPS and VDS rental are two separate services that are very similar. Some providers may publish materials on their websites explaining the differences between VPS and VDS, but this is not based on reality and can mislead users. In fact, both VDS (Virtual Dedicated Server) and VPS (Virtual Private Server) refer to virtual machines that run on physical servers, with each machine having its own set of technical characteristics.

It would be fair to say that these terms are synonymous and the choice of which to use is up to the individual. Users typically choose between a virtual dedicated web server and virtual web hosting, which has a shared pool of resources for all "residents."
