If you are interested in the web hosting market, then you know that one of the most relevant offers is a dedicated virtual server. What is it special about? It follows from the name: combines the advantages of virtual and dedicated hosting. In the article, we will analyze the VPS server in detail: what is it, what are its capabilities, advantages and disadvantages according to user reviews. We single out the cases when its connection is necessary.
VPS server - what is it?
Let's start with the definition. VPS-server (abbreviation for abbreviation - Virtual Private Server) is one of the types of hosting services in which the user is provided with a virtual server that has the maximum set of privileges. It emulates the operation of a physical real server. That is, there is also root access, installation of software and operating systems is possible.
Many have heard of the VPS server. What is it, we continue to disassemble. In this case, the space on one physical server is divided into several virtual ones. Accordingly, an individual user will be provided with one of these segments. The space is configured and functions in such a way as if you own your own stand-alone server. Additionally, access to the base software and hardware is provided.
And a little more about the VPS server. What it is? Emulation of a separate stand-alone physical server, as already mentioned. It allows you to run several virtual machines on the same machine, which is convenient and economical. Yes, there are some obvious limitations on the face. But a virtual dedicated server provides users with complete control, independent management (like ordinary dedicated servers). It has its own resources, processes, configuration, and offline administration.
Dedicated Virtual Server Features
What can a VPS server for Windows do? Inside it, you can do the following:
- Install your own applications and programs.
- Create author versions of system libraries (or modify existing ones).
- Manage a wide variety of files. Namely: change, add, delete and so on. This also applies to root and service directory files.
- Modify or customize any installed software.
The main advantages of choice
Why is a Forex VPS server used? The thing is its undeniable advantages. After analyzing user reviews, we identified the following advantages of such servers:
- Price. No matter how large the business is, this factor always remains decisive. It is for the price today that dedicated servers are an order of magnitude superior to their virtual "brothers." Renting a physical server is quite expensive. And buying your own car will cost the user several thousand (if not tens of thousands) dollars.
- Independence from hardware problems and crashes. Relatively cheap VPS servers are not hardware related. Therefore, in the event of its failure, they can be copied and transferred to another machine.
- Responsibility for the operation of the equipment lies not with the user, but with the provider, the service provider. We know that even the most advanced equipment has a service life and is morally obsolete. If the server is your own, then all the problems associated with its maintenance, updating lie with the user. Otherwise, it is the responsibility of the service provider.
- Guarantee of exclusive ownership of hardware resources. What does it mean? If you use a VPS server, the provider guarantees that the allocated hardware resources (such as a hard disk, RAM, processor) belong only to you. No one else will be entitled to use them. Therefore, the operation of such a server is faster, independent of other clients of the service provider.
VPS and VDS - what is the difference?
You could hear about VPS, VDS server. Are these different concepts? What connects them? Or maybe these are synonyms? Let's figure it out.
Let's start by decrypting the abbreviation:
- VPS - Virtual Private Server.
- VDS - Virtual Dedicated Server.
You could read the information that each of these letter combinations denotes its own type of virtualization:
- VPS - at the level of operating systems.
- VDS is a type of hardware virtualization.
But this definition is incorrect. Both of these concepts mean the same thing - a dedicated virtual server that runs on the basis of the physical. By the way, the terms appeared and developed simultaneously.
By the way, VDS is used even more often than VPS. Many providers believe that this term more clearly reflects the essence of the services they provide.
Principle of operation
Are there any specifics for setting up a VPS server? Note that in its functioning it will practically not differ from the traditional physical server:
- There is no limit to the number of hosted sites, domain zones, databases, etc.
- The owner of such a server is authorized to work with files, install applications and perform other actions specific to working with a physical server.
- It has its own IP address. It is not shared with another client. If necessary, the user can order additional IP addresses.
Such a server works completely autonomously from other virtual dedicated zones provided to other clients. The failure of one of them does not affect the "neighbors".
But what distinguishes it from a regular virtual VPS server is that it is protected from all kinds of DDoS attacks. The safety of information here is additionally guaranteed by the ability to create backups.
We offer you a detailed comparison of the VPS server with other popular today.
Advantages of shared hosting
Let's see what is the most beneficial hosting VPS-servers. The advantages are as follows:
- Providing full control. The owner of the VPS server has administrator rights (for Windows). Or root-rights. Therefore, it has the ability to customize its server to the needs of a particular project. Up to changing the operating system and installing other software.
- Minimum restrictions. As we have already noted, the owner of the server is not limited in the created domain zones, sites, databases. Borders are only within the resources of one such server.
- Independence. Full autonomy in relation to its "virtual neighbors". Users are independent, do not "pull" resources from each other. It is important to highlight the use of different IP addresses (in most cases, on a regular virtual server, the IP address is one for all).
Disadvantages before shared hosting
Install a VPS server or a regular virtual? Listing of the significant disadvantages of VPS before shared will help you make a decision. These are two points:
- Cost. The rental price of virtual hosting in the modern market is lower than the rental price of a dedicated virtual hosting . Sometimes the difference is very significant.
- The need for administration. A virtual dedicated server needs administration just like a real physical server. Accordingly, the user must have the necessary skills and knowledge in this area. By the way, the solution to the problem greatly simplifies the presence of the control panel - a number of providers provide it to its customers.
Advantages to a physical dedicated server
In this comparison, the advantages of choosing a VPS server will be as follows:
- Cost. The rental price of a dedicated virtual server is much lower than the rental price of a physical server, equal to it in power. Practice gives interesting results: the performance of the VPS server may even turn out to be slightly higher!
- Easy scalability. What is this expressed in? It is simple to make a virtual server more powerful: add an additional amount of RAM, a hard disk, strengthen the processor power, and so on.
Disadvantages in front of a physical dedicated server
The VPS server “loses” to the physical in one - this is the presence of a common disk system and a communication channel. All virtual dedicated servers, in fact, run on the same host machine. Therefore, they use one common disk system and access a common high-speed communication channel.
What is this fraught with? Unscrupulous users can abuse shared resources, interfering with the work of their "neighbors". However, many service providers have found protection against such a flaw: a special system is being installed to locate violators. Punishment measures apply to them, including disabling VPS.
When is a virtual dedicated server necessary?
In conclusion, we will answer this important question. Five reasons can be identified:
- You need your own server at the lowest cost. The price of "virtualka", as practice shows, is steadily declining. Sometimes it comes to ridiculous numbers. Therefore, this is the best solution if you want to place your sites and email somewhere. The limitation is only on the resources of your VPS server. In this case, you will always have full access.
- Ease of use. Installation and configuration are clear even to a novice in this business. In addition, many providers today offer ready-made templates with already installed samples. And the control panels "learned" to work with e-mail.
- Need for your own VPN server. How is it important? You can visually compare it with an encrypted “pipe” as a communication channel between your device (PC, smartphone, etc.) and a virtual server. That is, this format does not allow a third party to take possession of the information that you transmit to the Internet in any way.
- Create internal phone numbers. A VPS server is a great alternative to the expensive cloud PBX. This is the creation of your own secure telephone server with a large number of internal numbers. Moreover, the setup is simple - by the set of instructions freely available on the Internet.
- Remote computer. Suitable for all those who want to always have a PC with them, anywhere in the world. It does not break, is protected from data loss. In addition, his condition can always be returned to a fixed point.
We have sorted out such a new phenomenon in the hosting market as a VPS server. You know both its key features and advantages, and disadvantages.
