VPS / VDS (virtual dedicated server)

Premium VPS are located on servers with high-frequency processors, which significantly accelerates the speed of operations.

VPS is an opportunity for several clients to share resources of one server. Each client is allocated a certain amount of memory, processor cores and NVMe disk space. Therefore, everyone is guaranteed to get the resources that are allocated to him. At the time when the first virtual machines were launched to provide hosting services at the same time used the term VDS (Virtual Dedicated Server) and VPS (Virtual Private Server). But the term VPS is more popular, so it is the term you should focus on.

Dedicated server (dedicated server) - useful for projects that do not want to depend on neighbors who can affect the stability of the site. They need security and a guarantee that a sharp increase in traffic, for example, during an advertising campaign, will not lead to the fact that the site will be unavailable because of the limits;  

VPS is a dedicated server shared between a small number of clients. VPS allows you to save money due to the fact that resources can be purchased as the project grows. We can say that VPS server is a transitional stage for a project that does not have enough resources of shared hosting, but does not need the resources of the whole server.

VPS servers are divided into 3 types, the oldest and completely lost its popularity is OpenVZ. Servers running OpenVZ have lost their popularity because this virtualization system makes it possible to abuse hosting providers and engage in overselling. The remaining virtualization systems are XEN and KVM. These virtualization systems are very similar to each other, they do not allow you to engage in overselling as each virtual machine is rigidly assigned resources. We prefer KVM virtualization system in our work.

There are two main reasons why you need to use a VPS. The first is the need to install specific software that is not available on shared hosting, such as NodeJS, PostgreSQL, Redis, Sphinx. The second is when the site consumes too many resources and can no longer be placed on a shared hosting server.

First of all, it is worth paying attention to the country where the servers are located. Within the limits of one country time on data transfer makes 2 ms, if servers are outside the country, it grows as minimum in 10 times, up to 21 ms, and even more. Despite the fact that the millisecond is a small value due to the specifics of the TCP protocol, which is constantly exchanging information between the recipient of information and the server appear noticeable delays.

The second indicator is the virtualization system, preferably KVM.

The third thing you should pay attention to is the availability of backups and how functional the control panel is. It is much more convenient to press a few buttons in the control panel and get the result than to write to tech support and wait for an answer.

Finally, it is worth paying attention to the level of trust in the company from which you are buying services.

The minimum cost of a VPS, without administration, is as follows 6 € per month.

We have a 30-day test period of VPS usage. During the 30 days after placing an order you can cancel further use of VPS and get the whole paid amount back without any questions. The only thing that is non-refundable is the payment for the use of licenses on the control panel. Therefore, for testing we recommend using a free control panel, which are now fortunately a large number.

Today VPS servers are installed in Ukraine, Kiev. If the project is focused on Ukraine, this is the most optimal location of servers, as all major international communication channels come to Kiev, there are traffic exchange nodes. Usually a request between cities of Ukraine passes for 2ms, while requests to Germany, Poland and neighboring countries — at least 20-40 ms, USA — more than 100 ms.

Hosting Ukraine provides an opportunity to install your own operating system on VPS servers. In the VPS control panel there is an option that allows you to specify a link to the image that you want to install, after which it is automatically downloaded and starts the installation, which can be continued through the VNC console. The installation is completely similar to the one that takes place on a regular computer.

All VPS are provided without administration, they are perfect for IT specialists and developers who are able to install and configure the necessary services themselves. If you do not have skills in Linux administration and do not want to study, then pay attention to the service   Business hosting, are the same VPS, but with a control panel like shared hosting.
