What is the difference between a virtual server and a regular server? As a rule, this is the question that arises in a person who is thinking about renting a VPS/VDS in Ireland. What is good about renting a server in this state? The first thing to note is the favorable location. Ireland is attractive for large companies and startups, information technology is developing here, just like in the whole of Britain. Renting a virtual server in Dublin - the heart of the state - is an optimal solution if you plan to develop your business with a bias towards the British audience.

What is the difference between UPU and VDS?

VPS and VDS in Dublin is a service where the hosting company provides the client with their own virtual machine. The virtual machine is managed in the same way as a physical machine. Due to the fact that the client has root rights, he can make almost any changes in the operation of the virtual server and software. At the same time the cost of VPS/VDS rental is many times lower than renting a dedicated server. This is one of the advantages of this service.

This service is ideal if you plan to optimize the cost of renting a server, while wishing to maintain performance at the level of the real server. A solution for fast-growing and dynamic projects (social networks, applications, resources with high daily traffic). You can rent UPU/VDS in Ireland to meet the needs of demanding and specific projects. As you can see, there are two terms in the name of the service at once - UPU and VDS. Many customers do not attach importance to this, but in fact there is a difference between VPS and VDS.

What is it? In the West, this abbreviation is perceived in the same way, that is, neither hosts nor clients do not feel the difference between these two designations of actually the same service. As for the Russian-speaking environment, as a rule, VPS is associated with OpenVZ, while VDS is mostly associated with KVM. To put it simply, in the first case we are talking about hardware virtualization, and in the second case - with the help of the operating system. This knowledge is enough to understand the main difference between the two acronyms.

OpenVZ technology

The technology is implemented at the operating system level. It means that all virtual machines are based on one modified Linux kernel. Each virtual machine is a separate server with its own management system to which administrative access is granted.

But the peculiarities of this technology impose a certain imprint, which must be taken into account by the client before renting a virtual server in Ireland:

• the choice of available distributions is limited only to Linux;
• only one file system is available - ext4;
• there is no possibility to modify the kernel, so it will not be possible to run some non-standard modules, in particular OpenVPN, PPTP, IPSEC;
• management of the firewall and running processes is limited;
• the administrator has access to the entire contents of the virtual server.

But, as already mentioned, this technology also has a number of advantages, such as ease of startup and configuration. In just 10-15 minutes after ordering the service, you will be able to host your project on VPS/VDS in Dublin and receive the first visitors.

KVM technology

When we talk about KVM, we mean virtualization with the help of software solutions - hypervisor. This is a specialized software that is the manager for all virtual machines. The program provides each of the containers with access to hardware resources and creates conditions for their functioning.

What is good about KVM technology? First of all, it gives the client more options. Specialists call KVM the most worthy replacement for a dedicated server. Here is a list of advantages, what is so good about this technology. And its advantages are as follows:

• it is possible to work with any operating system - Windows, FreeBSD, you can use any non-standard build;
• the client can format disk space for any file system;
• the client has access to sockets, processes, and the ability to modify the OS kernel;
• the highest degree of privacy: no one but the user has access to the contents of the container.

What about performance, power of servers virtualized by different technologies? It should be said that there are differences, albeit insignificant ones. OpenVZ technology dynamically distributes all available resources between all machines. Thus, with just one mouse click you can change the limits - change and distribute the available resources in a different way.

But in the case of KVM there is no such possibility: all servers receive a strictly limited amount of resources, and it is not possible to dynamically distribute them. At the same time, it should be noted that KVM is an extremely reliable solution characterized by high fault tolerance.

The only disadvantage is the lack of flexibility. However, 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, make a decision about renting a server in Ireland.

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

So, for what purposes you may need to rent VPS/VDS in Ireland? This is a universal solution for all occasions.

Here is only a minimum list of what you can do after ordering the service:

• hosting internet projects;
• VPN installation;
• use of IP-telephony;
• organization of a remote desktop;
• development, setup;
• software deployment;
• launching a game server;
• use of mail services;
• trading on the stock exchange.

It is important to properly use the capabilities of VPS/VDS, you do not need to engage in spamming. Otherwise, penalties will be imposed, and you will no longer be able to use the services of the hoster.
