Virtual server in Serbia is a service provided by hosting companies, which implies granting the user rights to manage servers with maximum privileges. This is how root rights are granted, it is possible to install any operating system and the necessary software. Several mini-servers work on one server. They are virtualized, that is, they are created by software or hardware. Renting a VPS/VDS in Serbia, as well as in other European countries, has its advantages. What these advantages are, we will tell you next.

What is the difference between VPS/VDS?

There is no fundamental difference. It is one service that involves transferring the user to the management of the server. There is a physical machine, which with the help of software or hardware tools is divided into several equal parts - virtualized. As such, there is no difference between VPS and VDS.

In the Russian-speaking environment, the service has one name - virtual server. In the English-speaking segment of the Internet VPS and VDS are usually distinguished. However, both terms appeared at the same moment and developed in parallel. But at the moment they are united under the "sauce" of one service.

How does VPS/VDS work?

How does VPS/VDS work? If it is hardware virtualization, a hypervisor is used. It is used to create virtualization layers where the virtual server provided to the client is separated from other virtual machines. All clients are hosted on a single physical machine. They are neighboring but do not interfere with each other.

Through virtualization technology, the VDS server starts to work as a separate physical server. The client chooses Serbia as the location of his project, and is satisfied with consistently high speed, reliability and responsiveness of the server.

On any VPS/VDS is not difficult to put the OS you need (Linux, Windows Server). The user will be able to use root-access, install software at will, work with files and applications.

It is important to note the fact that a virtual server in Serbia has no restrictions on the number of hosted projects, databases, FTP, e-mail boxes. The owner of the server (tenant) can perform practically any manipulations with it, namely:

• install OS;
• install software;
• customize its operation.

Interaction with the VPS/VDS occurs as with a real physical server. But it should be noted that renting a virtual server will cost you many times cheaper than the same service, but in relation to a dedicated server.

Each mini-server (VPS/VDS) operates on a separate IP-address, if necessary, the user can purchase an additional one. VPS/VDS operates independently of other mini-servers, which are on the same hosting machine. That is, a failure, accident, any unforeseen situation on one server does not affect the functioning of other servers.

OpenVZ technology

This is what is called virtualization at the OS level. It assumes that each virtual machine is based on the Linux kernel. Each such mini-server is a separate solution with its own management system. The tenant gets full access to it for comfortable work and interaction.

When ordering the lease of VPS/VDS, you should take into account that software virtualization deprives you of:

• choice of OS;
• choice of file system, only ext4 is available;
• you will not be able to modify the kernel, which means you will not be able to run non-standard modules such as OpenVPN, PPTP, IPSEC;
• the administrator has access to the entire contents of the virtual server.

But this technology is also characterized by a lot of pluses, such as ease of startup and configuration. In just 10-15 minutes after ordering the service, you can place and launch a project on a VPS/VDS in Belgrade or any other Serbian city.

KVM technology

If we talk about KVM server virtualization, it suggests the use of a hypervisor. This is a specialized software that acts as a manager for all virtual machines. Hypervisor forms access of each of the containers to hardware resources and creates all necessary conditions for their joint work.

This method of virtualization provides each mini-server owner with many more options. Experienced computer specialists identify KVM as the best replacement for a dedicated server.

Let's list the main advantages that KVM provides:

• you can work with any OS - Windows, FreeBSD, any non-standard build;
• you can format disk space for any file system;
• you have access to sockets, processes;
• you can modify the OS kernel;
• the highest degree of privacy: only you manage the server and have access to it.

Regarding the power of the servers, it is worth saying that there are differences, albeit insignificant. OpenVZ technology allows you to dynamically distribute resources between all machines.

KVM does not provide such an opportunity. All servers receive a strictly limited amount of resources, and it is impossible to dynamically distribute them. KVM is an extremely reliable solution that is characterized by high fault tolerance.

The disadvantage is that it is not very flexible. But the advantages completely outweigh the disadvantages. However, each case is different, so it is important to consider the needs of the project, and, based on this information, to make a decision about renting a server.

In what cases do I need to rent a VPS/VDS in Serbia?

In what cases do I need to rent VPS/VDS in Serbia? This is a universal solution for all occasions.

As a rule, hosting resources are enough for small blogs. As the project grows, Virtual Private Server or Virtual Dedicated Server may be required.

Lease of virtual and dedicated servers are ordered by:

1. Outsourcing companies. You develop customer software and need high-quality and fault-tolerant servers for projects of any complexity: news portals, aggregators of discounts and services, mobile applications.
2. Product companies. You create and develop your own solutions for various spheres (medicine, industry, automotive, real estate, law, games and entertainment and so on).
3. Private clients. You independently develop projects, think ahead about scaling the site, lendings, applications.

Lease of virtual and dedicated servers is suitable for working with projects:

• aggregators of discounts, news, services, companies, etc.;
• parsing of sites and online stores, creation of bases;
• applications for games, entertainment, dating, health tracking;
• sites with high traffic, which is constantly increasing;
• online stores and ecommerce, as well as many others.

If desired, you can configure virtual / dedicated servers in such a way that they will be suitable for 90% of projects and businesses, while remaining convenient in terms of management, administration and solving any arising difficulties.

Renting a VPS is a convenient and affordable tool that allows you to optimize costs and take your business to a whole new level. You should not order a VPS/VDS for illegal activities in the national or European region (viruses, ransomware, fraud, spam and deception or others).

Comparing VPS/VDS with shared hosting

Compared to conventional hosting, this technology offers the client a number of features and advantages:

• full control: you get root (for Unix) or Administrator (for Windows) level access rights. You will be able at your discretion very subtle and flexible to customize the server to meet the needs of a particular project;
• minimum restrictions: the number of possible connections of sites, databases is limited only by the capabilities of the server itself;
• independence: each virtual server works separately from each other, despite the fact that they all share the performance, power of one physical machine (host server), none of the neighbors use other people's resources, projects are isolated and do not contact each other in any way.

It is important to note the fact that VPS/VDS in Serbia is slightly higher in price than shared hosting, but not significantly. In general, you can rent a virtual server inexpensively, and many hosting companies offer discounts and promotions, which makes it cheaper to place projects on the network and reduces the cost of their maintenance.
