![]() in the case of company expansions), the reverse path is also open to you: If the existing resources are no longer needed, you can downgrade with relatively little effort.ĭisaster recovery: The VPS also scores points in the event of a hardware failure. In addition to the possibility of a need-based expansion (e.g. This not only reduces acquisition costs, but also automatically reduces ongoing expenses and power consumption.įlexibility: The VPS can be customized to meet your specific needs. If you also use an operating system such as Microsoft Server 2012, there are no additional costs involved.īy using virtual servers, you not only save on acquisition costs, but also reduce your power consumption at the same time.Ĭost efficiency: Instead of purchasing several physical servers, you only need one for virtualization. In addition to the possibility of running several (different) operating systems on a single system, you benefit from a whole range of other advantages:įast availability: you don’t have to order hardware or plan budgets for a virtual machine first, because it can be created simply with a few mouse clicks on the infrastructure you already have. Using a virtual server pays off in many ways. If required, you simply hand over the central administration of the virtual servers to your cloud provider. The advantages and disadvantages of virtual servers at a glance However, they are always sufficient for a private web project. With these, however, you almost always have to accept restrictions in the configuration and in the selection of the operating system. Good to know: There are also some providers on the Internet who will provide you with free vServers. He must also ensure that the individual VSPs do not (cannot) communicate with each other and that the data is thus protected from unauthorized access. In this case, the provider operates the (virtual) IT infrastructure that customers rent in order to outsource their services or data inventories to it. ![]() In this way, several customers share a “real” computer.Īnother typical variant for virtual servers are cloud services (e.g. The virtual server behaves like a conventional server, but it is operated together with other VMs on a common platform. VPSs can also be found in web hosting: with virtual server hosting, a provider makes server services available to you for your applications and services that are not assigned to any specific hardware. Employees can access their data from anywhere, since they log in via the client but perform their work directly on the server. In the enterprise, they are often found in the context of “thin clients”, where multiple virtual desktops are centralized on a real server. There are many application areas for VPS. Thin clients are a typical application area for virtual servers. However, the disadvantage of this method is that the same operating system must be run on all guest systems In operating system level virtualization, there is no hypervisor, but the function is part of the host operating system. In contrast, the guest servers know each other in a so-called paravirtualization system. In full virtualization, the individual VPSs remain completely independent of each other. This is equipped with management software, the so-called “hypervisor” (also: “virtual machine manager”, VMM), which is responsible for resource distribution.īasically, a distinction is made between three types of server visualization: ![]() The infrastructure usually consists of a powerful physical server running the virtual machines. This means the software running inside it cannot manipulate the actual computer. The VM provides its own (virtual) hardware (including CPU, RAM, HDD, Ethernet) and is separate from the rest of the system. It is an image file that replicates the architecture of a real or hypothetical system. One of the biggest advantages is that you can run several different operating systems on the same physical hardware.Ī virtual private server (VPS) is a virtual machine that is used as a server. ![]() What is the advantage of virtual private servers? Virtual servers are often found in connection with thin clients, in web hosting and as cloud services. What is a virtual server?Ī virtual private server (VPS) is a virtual machine that is used as a server. In this article, you will learn how a virtual server works and what advantages and disadvantages the technology brings. In addition to creating backups, vServers also allow applications to be run on operating systems for which they are not actually intended. This is a software-generated copy of a server machine that has the same functions as a dedicated server. In order to save costs and resources in infrastructure, many companies resort to so-called virtual servers (vServers for short).
