You have a business and a website. The site must be available 24 hours a day: accept applications, form orders and issue invoices. When the site is unavailable, customers leave, and you get sad and lose money.
In order for the site to be always available, it needs reliable web hosting. Hosting apartment for your website.
Virtual hosting is a communal apartment. Several sites with a shared kitchen, hallway, processor power and disk space are located on one server at once. If a neighbor has a noisy party, guests will not come to you.
A dedicated server is a private apartment with as many rooms as you want. Only your website lives in it, neighbors do not store their things in disk space and do not touch RAM. Your own apartment is good, but expensive.
If you do not want to live in a communal apartment, but there is no money for your apartment, there is an alternative solution — VPS hosting.

What is VPS/VDS Hosting

A VPS (Virtual Private or Dedicated Server) is a virtual dedicated server. It is located on a physical server, but is isolated from other VPS. Therefore, when web hosting multiple sites on the server, they do not affect each other's performance.

In other words, a VPS is a rented apartment. You don't have to pay for it like for a whole house and you don't have to share it with neighbors. But you can re-glue the wallpaper, change the laminate and rearrange. And if you want to add a couple more rooms.

    VPS allows you to save on the purchase and maintenance of a physical server.

Its owner gets full access to his virtual server and can work with it in the same way as with a regular one:

    Install server applications and any software.
    Create any number of websites, databases, mailboxes, domains, FTP accounts.
    Configure the system and optimize resources for a specific project.
    Use your own IP address, not shared with other clients.
    Create backups when moving the site.

You only pay for the server resources that you use. For example, web hosting provider has a minimum cost of renting a VPS on Linux - $2, on Windows — $5 per month when paying for a year.

You can change the configuration of your VPS server at any time online. For example, before the New Year holidays, you reserve additional processors. And as soon as the peak has subsided, you turn it off so as not to pay extra.
Who needs a VPS

A virtual dedicated server is suitable for hosting sites, online stores, software development and testing, updates and content management systems (WordPress, Drupal, Joomla, 1C-Bitrix, OpenCart). In addition, you can transfer video conferences, payments, accounting and other services to VPS.
How to choose a web hosting provider

VPS protects against data loss and allows you to create backups regularly. But not all cloud services are equally secure. For example, in 2017, the hosting provider Cloudmouse lost user data, including backups.
The same thing happened in March 2018 at the British web hosting provider 123 Reg. Therefore, when choosing a VPS hosting, it is important to assess the reliability of the provider. There are several criteria worth looking at.
1. The provider has its own data center

A data center is a room where servers are located. If there is one, it means that the company itself is responsible for the entire chain of service provision and ensures that the servers work without failures.

All equipment is located in its own TIER III data centers, the Tier III data center does not need to be stopped for repairs and preventive maintenance. In Moscow and TIER IV, this data center is ranked among the most secure data centers in the world. It is located in a former military command center in the Alps, and the data is reserved here twice: there are not just copies of all the data, but copies of copies of all the data. in Switzerland. If some equipment fails, you won't even know about it: the provider will switch to another data center, everything will work as before.

The company plans to place the equipment in two more data centers: in Equinix LD8 in London and in a data center based on one of the largest communication hubs MMTS-9 (M9) in Moscow.
2. Data centers have a high fault tolerance rate

The reliability of VPS web hosting directly depends on the equipment: the quality of motherboards, disks, memory and other components. The servers must be new, not purchased on the secondary market.

It has direct contracts for the supply and maintenance of Huawei equipment. The fault tolerance level of the data center in Moscow is 99.98%, the data center in Switzerland is 99.995%. partners include Exchange, VTSIOM, FINAM, GettTaxi and Delivery Club.
3. The provider insures the data against the risk of loss

Data insurance against the risk of loss is a new service in the cloud storage market that is available to web Hosting provider customers. It's free: the risk of compromising the data of all customers is insured by AIG. Hosting provider offers its legal entity clients an increase in insurance coverage both in amount and in risks. The data will also be insured against failures on the communication channel.
4. There is a test period and round-the-clock technical support

Ordering and installing a virtual server is fully automated: the whole process takes two minutes. After that, it is immediately available for work.

Infrastructure management tasks (creation and removal of servers and networks, configuration or tariff changes) are solved in the personal account. To understand how everything works, web Hosting provider gives one day of free trial period.

If you have any questions, you can contact the support service at any time, it is available around the clock. On web Hosting provider website there is a FAQ and a reference book where the mechanisms of operation are described in detail.
5. The provider does not raise the price and sets flexible tariffs

Hosting provider has some of the most favorable tariffs among other web  hosting providers. This is possible due to the automation of the service. You can choose a ready-made tariff, create your own virtual server configuration, or pay only for the resources used.

In the first two cases, the cost of the VPS is fixed, with payment once a month. You can additionally order protection against DDOS attacks and viruses. The Windows Server OS license is included in the package.

In case of payment for resources, the amount that your server used is debited from the account every day. That is a good option if you don't always need huge computing power, but you want to have it in stock. If you don't know which tariff to choose, support service will help you determine your needs. And don't forget that you can change the tariff for free at any time.


Comparison of VDS/VPS with virtual (shared) hosting.

Advantages of using VDS/VPS compared to virtual hosting:
Full control: the owner of a virtual dedicated web server gets root-level access rights (for Unix) or Administrator (for Windows), and can fine-tune the server to the needs of a specific project, up to installing the necessary software and changing the operating system.
Minimum restrictions: the number of created sites, DBs, domain zones, ssh- ftp- email users is limited only by server resources.
Independence: virtual servers-"neighbors" on the host machine work in isolation and do not "pull" resources from each other, and also use separate IP addresses, while on a regular virtual hosting several sites often use the same IP address.

Disadvantages of using VDS/VPS compared to virtual hosting:
Price: the cost of renting a virtual dedicated server is usually significantly higher than the cost of virtual web hosting.
But we offer comparable rates in terms of cost.
The need for administration: a virtual server needs to be administered like a physical one, so the user needs certain knowledge and skills in this area. The presence of a control panel makes it easier to perform typical tasks: for our customers, we offer the ISPmanager panel.

Comparison of VDS/VPS with a physical dedicated server.
Advantages of using VDS/VPS compared to a dedicated server:
Low cost: renting a virtual dedicated web  server costs the user much cheaper than renting a physical server comparable in capacity. At the same time, the performance of VDS / VPS may even be higher (see our study)
Simple scalability: It is very easy for a virtual server to add power 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 divided, use the same disk system and a common high-speed communication channel for all.
This means that some users may abuse the use of resources and interfere with other clients.


It is necessary to analyze the need for Windows several more times-and on sufficiently weak (weaker than a dedicated server) VPSs — for most tasks that initially seem to be solved only under Windows, Linux will be quite an adequate replacement.
For example, ASP.NET runs quite well on Linux. And I 'm not even about .NET Core, although its appearance is not bad so pushed the development of the same Mono.

Why, I keep one game server of a fairly old toy under Linux at all, although at the time when this toy was being made, no one thought about Linux for games — even for servers. And nothing, Wine copes quite well.
