What is a virtual server

So, a virtual server refers to a service in the form of renting computing resources provided by a cloud provider. This includes processor capacity, memory and disk subsystem. By renting such an arsenal of resources, the customer can "build" a virtual server according to his own requirements with the possibility of vertical scaling.

buy vps are very similar to traditional servers on which the OS and applications are installed. However, instead of purchasing basic hardware from the client, virtual servers require the organization of a virtual infrastructure using a hypervisor. In addition, virtual servers require physical equipment, but this issue is covered by the hosting provider. Note that virtual servers on the market of cloud services are classified by hypervisor, operating system, service format and tasks. However, the last two classifications are more popular among customers, because the customer is often faced with a specific task and proceeds from the possible options for its solution. On the other hand, the simplicity or complexity of the realized project determines the most appropriate service format.


Despite the fact that a virtual server is not designed to solve complex tasks of large businesses, the applicability of such a service is quite suitable for projects of small and medium-sized organizations, which make up a fairly significant part of the market. Moreover, virtual server has a number of advantages and strengths:

# Cost minimization There are several aspects that explain the overall cost savings: reduced capital expenditures, no energy bills and other associated costs. In addition, a virtualized server provides 85% resource utilization compared to 10% in a traditional server view. According to research agency Gartner, using a virtualized server reduces total energy costs by up to 80%. # Efficiency By using a virtual server, a company reduces the burden on its own IT department. In this scenario, there is no need to use physical servers and as a result, the IT team no longer spends time monitoring and maintaining previously used hardware.  

# Backups have traditionally been a headache for many IT departments. It's not always possible to back up important data on time - more often than not, data is backed up and the OS itself is forgotten.

# No upfront investment Servers, storage, virtualization software, network configuration - these and more are expensive. Using a virtual data center reduces these costs, while the customer uses the best infrastructure at no significant cost.

# No encumbrances Maintenance of equipment is time-consuming and represents a significant cost. In addition, a company's staff must have highly skilled professionals with in-depth technical knowledge. With a virtual data center, companies save time and minimize costs by relying on the expert technical support of a cloud hosting provider.

# High performance The virtual data center infrastructure is built using hardware and software solutions from market leaders Cisco, VMware, NetApp and others. Thus, the customer receives guaranteed reliability, high performance and maximum compatibility with various services.
