In each industry there is a huge amount of different terminology and "professional slang" that are used for intrastructural communication. Accordingly, a person who does not have a direct relationship to this industry, it is quite difficult to understand the intricacies of terminology, and most importantly - in the appointment of objects or services. This is most directly related to the computer sphere, where users communicate with each other all the time with abbreviations and “slang expressions”. But many users who use computers at the household level continue to get lost in the abundance of abbreviations, which affects the basic understanding of what kind of service they get and whether they pay for the same thing twice. In this article, we will talk about one of these "phenomena", which can be formed due to the lack of clear explanations (including directly from providers) about what the functionality of VPS and VDS is and whether there is a difference between them.
Differences between VPS and VDS.
Is there any difference
So, it’s worth starting with the fact that some providers, including even large organizations from Russia, “love” to use the abbreviations “VPS” and “VDS” to denote “supposedly” various technical services. “VPS” is short for “Virtual Private Server”, it is translated as “Virtual Private Server”, and “VDS” is “Virtual Dedicated Server”, that is, “Virtual Dedicated Server”.
Do you know what the difference is between them? The only difference is that the term "VPS" came to the Russian-speaking user market, as they say "from abroad, " that is, from the existing offers of foreign providers. And "VDS" is a domestic name that has gained its distribution in runet, including, thanks to the previously quite popular management system "VDSManager". That is why if you ask a foreign provider: “Can you provide me with VDS?”, You will get, if not a negative answer, then at least a puzzled look, because “abroad” few people know at all about the term “Virtual Dedicated” Server "and even less of those who use it.
But in Russia, some, to put it mildly, impious providers use the ignorance of their users and offer a catalog of services, where “VPS” and “VDS” are indicated in different positions and with a huge difference in cost. Seeing this in the price list, you should know that here they are trying to deceive you from the first moments and you should avoid this supplier.
Principle of operation
It is quite possible to accept the fact that some providers and users share “VPS” and “VDS” for different services, since it is generally accepted that the first works on the basis of OpenVZ technology and the second on KVM technology. This is by no means a “tradition”, but only the most common “blanks”, since it has already been said that there is no difference between them:
- OpenVZ is an established virtualization technology based on the operating system level. That is, all the “visitors” are based on a single Linux kernel and run from the main operating system, and each of them is independently engaged in emulating the operation of a physical server.
- “KVM” is a technology that helps to realize the creation of a certain analogue of a physical server. The basis of everything is the complete isolation of a single virtual machine from all other “neighbors”.
The main difference between “OpenVZ” and “KVM” is that when using the first option, you will not be able to change the operating system and will have to work exclusively on the basis of “Linux”. But "KVM" in this regard is more flexible and allows you to install as familiar to all Windows, including the various author's assembly.
These are just a few examples of what technologies VPS / VDS are built on (Virtuozzo, FreeBSD, VMware, XEN, Hyper-v), but, so that it is not laid down, each user will receive one single result - managing a part of a dedicated server on real car.
So, from all of the above, you can make only one conclusion and it lies in the fact that there is no actual difference between "VPS" and "VDS". It is necessary to pay attention not to these letters, but to what technology the provider uses to realize its service. You should not succumb to common misconceptions, if you are offered “VPS”, relatively speaking, 100 rubles each, and VDS 500 rubles each, allegedly indicating that these are different services, then you are at least trying to deceive you.
