For anybody it is not a secret that today requirements to a hosting constantly grow. Web projects all become complicated, and work with modern control systems of a content demands serious expenses of machine resources. Meanwhile the wrong choice of a hosting can lead to slow work of a site that, naturally, will not be pleasant to visitors. And in certain cases this moment in general can appear critical. Especially it is true concerning the web projects which are engaged in electronic commerce: Internet shops, Internet banks, platforms B2B, electronic payment systems and etc. Until recently the allocated server (or collocation - the same server, but belonging to the owner of the web project) was unique really reliable variant of a hosting. However at its cost such variant presumes to itself not all, but only large sites. Average web projects had to be content with usual virtual servers and somehow to “get on” with the neighbors in the computer. Fortunately, the situation has changed.

So, the virtual allocated server. Many readers, already for certain, faced this concept and know that it is a question of the Russian name of technology VPS (Virtual Private Server) which sometimes also named as the VDS (Virtual Dedicated Server). The essence of this working out is reduced to the following. One computer by means of the special software is divided into some virtual personal computers, each of which has its own operating system with all established programs, options and the information. And in an operating time the machine resources are distributed in such a manner that any virtual allocated server is not crossed in any way with others, and works absolutely irrespectively from them.

What, gets the customer who has paid to the hosting-provider for the virtual allocated server? The answer to this question is very simple. Actually he receives in his order the real allocated server, the truth, slightly smaller capacity, rather than modern cars. However, the client himself chooses the tariff plan which defines the guaranteed minimum of machine resources, sufficient tasks in view for the decision. If to speak more particularly, users of the virtual allocated servers have full access to the system with the rights root. Actually it gives to the manager of a site unlimited possibilities on adjustment of OS, a configuration of all parameters, installation of any appendices, libraries and other personal computers. Well and if still to consider that fact that the virtual allocated server possesses its own IP-addresses, filters and addressing rules, it becomes clear that “outwardly” it differs nothing from the present allocated server.
However, there are certain distinctions between them. In particular, the owner of the virtual allocated server has no physical access to it. However, it is completely not terrible. More often access to “iron” is necessary in two cases: for an upgrade of the machine or in case of occurrence of different states of emergency. The first variant in the virtual allocated servers is replaced with change of the tariff plan with increase in the guaranteed minimum of machine resources. The provider is also responsible and for the working capacity of a server ,so its experts are engaged deleting various accidents. Besides, the owner of the virtual allocated server cannot change an operating system installed on it (the truth, some providers offer their client 2-3 variants on a choice). On the one hand, such limitation is unpleasant. But on another - the client is relieved of necessity of constant updating of system, installation of new patches: technical experts of the hosting-provider are engaged in all that.

Before you buy any web hosting, you need to go through the hosting reviews routine. Surely you need to be realistic and understand that now every cpanel hosting will be real. But if you go through the nice number of web hosting unlimited sites - you will see the true picture.
