Advantages of using VDS/VPS compared to a dedicated server:

Low cost: renting a virtual dedicated server costs the user much cheaper than renting a physical server of comparable capacity. At the same time, the performance of VDS / VPS may even be higher (see our study)
Easy scalability: it is very easy for a virtual server to add capacity in the form of additional RAM, processor cores or hard disk space.
Cons of using a VDS/VPS server versus a dedicated server:

Shared disk system and communication channel: all virtual servers running on the same host machine, provided that the main resources are shared, use one disk system and a common high-speed communication channel for all. This means that some users may misuse resources and interfere with other clients.

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". ::)

How is VPS different from VDS?
There is a popular opinion among inexperienced users that there are two different, but very similar services — VPS and VDS rental. This myth is supported by unscrupulous providers (we will not point fingers), who publish materials on their official websites with a detailed story of how VDS differs from VPS.
They take the type of virtualization as a basis: allegedly, VPS implies virtualization at the operating system level, and VDS — at the hardware level.

Unfortunately, this has nothing to do with reality. On the other hand, this is a great opportunity for a user who is just getting acquainted with traditional IT services to immediately understand which provider it is definitely not worth contacting.

By the way, if, among other things, you see that there are different tariffs on VPS and VDS, our good advice to you is: run away so that your heels sparkle.
But let's still try to figure out what these two abbreviations mean.

WHAT ARE VDS AND VPS?
VDS (Virtual Dedicated Server) in English means a virtual dedicated web server. VPS (Virtual Private Server) is a virtual private server.

In fact, in both cases we are talking about a virtual machine that "spins" on a physical server. There may be several such machines on the same hardware. It is important that each of them works absolutely independently — it has its own set of technical characteristics: the number of cores, the amount of disk space, etc.

In other words, it would be fair to call such a web  server both "private" and "dedicated" — its resources are completely at the user's disposal. Therefore, it is possible (and necessary! — don't let me mislead you) to say that the terms VPS and VDS are synonymous. How to call such a service is a personal choice of each individual.

For more information about what tasks you can use a virtual server for, read the article "What is a VPS web server for?".

EVERYTHING IS LEARNED IN COMPARISON
And yet, what can VPS be compared with? As a rule, users choose between a virtual dedicated web server and virtual web hosting. The latter, by the way, is organizationally arranged as follows: a web server and a database server are "spinning" on a physical web server - all this is regulated by a control panel (cPanel, for instance). The "residents" of the virtual web hosting actually have one common pool of resources.
