What is a VPS/VDS?

When looking for a cloud service provider, we often come across abbreviations. Some are clear to us, others are not very clear, others cause doubts, and sometimes real confusion. IaaS, SaaS, PaaS, and VPS/VDS are not a complete list of abbreviations that can confuse an inexperienced user. Therefore, before choosing a service, you need to understand it.

Today we will talk about the VPS / VDS service, the debate about which has not subsided to this day. Some believe that VPS is no different from VDS and are synonymous, others argue that these are two different, but similar services and others refer only to the difference in the type of virtualization. But how does it really work? Let's figure it out.

VPS / VDS - is there a difference for the client

As companies move their business more and more online, there is a growing need for cheaper ways to set up an IT infrastructure. The easiest option is to start using virtual servers that have replaced physical hardware. This is where the VPS / VDS service will help, which often closes simpler projects and is mostly suitable for small companies.

It should be noted right away that the difference between VPS and VDS is imperceptible for the client since it is like an invisible thread: it seems to be there, but its significance is so small that you can pass by and not notice. And the principle of separating terms appeared only in Runet, there is no such practice in the West. Differences are more likely to be noticeable to the provider in terms of the implementation of the solution and the virtualization technologies used. The client will notice the play on words more, for this it is enough to look at the terms:

VPS (Virtual Private Server) - virtual private server

VDS (Virtual Dedicated Server) - virtual dedicated server

Like it or not, the meaning remains the same: both VPS and VDS are virtual servers running on the basis of a physical one. And no matter how it is called - private or dedicated, the significance and ultimate value of this does not change: the server resources are at the disposal of the user. This suggests that the client has the right to independently decide which OS to choose and how many resources to assign to a particular machine.

To deploy a virtual server, the provider often offers two options: the ability to determine the configuration yourself, or use ready-made solutions. In both the first and second cases, it takes several minutes to create a virtual server.

Features and Benefits of VPS/VDS

Since virtualization broke into the lives of many companies, customers began to gradually move away from the on-premise model toward virtual servers. This is logical because a virtual server works on the principle of a physical one, only with much greater capabilities, and allows you to save your budget. Let's take a closer look at the benefits:

Benefit 1: Scaling Flexibility

Unlike a physical server, whose resources are finite, a virtual server allows you to increase or free up any number of resources. The beauty comes down to the fact that the VPS / VDS server can be brought to the desired configuration. Here the principle works - take as much as you need. Such opportunities open wide horizons for the client, removing the restrictions imposed when using iron in their own server room.

Benefit 2: Full control and admin access

If we draw an analogy with virtual hosting, VPS / VDS, in comparison with the first, makes it possible to connect to the server with administrator rights. This suggests that the client gets the flexibility in the form of self-management and performance of tasks, whether it is changing the OS, installing the required applications, their subsequent configuration, or access via SSH, and other operations.

Benefit 3. Personal IP address

VPS / VDS is, first of all, independence from “neighbors”, when virtual servers operate in complete isolation without pulling resources from each other. It is important that each such server is given a unique IP address. And if the client wants to host a site on the server, it will be tied to a unique identifier. This will eliminate the situation inherent in conventional shared hosting when several sites use the same IP address.

Benefit 4. High level of security

An important point to pay attention to is guaranteed security. A virtual server differs from other types of hosting in reliability and security. VPS/VDS servers hosted on the physical equipment of the provider are isolated from each other, which excludes access by third parties from neighboring virtual servers.

Advantage 5. No restrictions

A virtual server, due to the ability to use resources on-demand, allows you to host any number of websites, databases, or mailboxes on it. All that is required of you is to decide on the parameters of the disk subsystem, processor, and memory.

Examples of when to use VPS/VDS

If you are not completely sure whether a virtual server is suitable for your tasks, here is a ready-made checklist for you. Go through the list to the end and find out if you should use VPS/VDS.

Examples of when to use VPS/VDS

Online projects with a high level of attendance

Online stores that do not have enough virtual hosting options

The need to host a large number of databases, websites

The need to allocate a guaranteed amount of resources

Software testing and demonstration of the capabilities of the developed solutions

Mail server and collaboration support

Summing up

Taking into account the features of VPS / VDS, the client gets ample opportunities for solving various problems. Reducing operating costs, a quick release to production, no need to purchase and maintain your own equipment will allow you to concentrate on developing your own business. And don't forget to test drive. Before you pay for the service, you can always try the service by leaving a request for a free test access. Use, evaluate and make only the right decisions!
