really far away from theVirtualization and cloud computing have been used to solve many technical and business problems for years. The main reasons why many companies use these technologies are mainly the low costs of IT infrastructure, performance and scalability. The concept of virtualization is not unknown to technology enthusiasts, but it is a completely new concept to entrepreneurs or ordinary computer users. This article therefore aims to introduce you to the topic of virtual servers – what they are, why you need them in your business and what are the basic principles that make them work.
What are virtual servers?
A virtual server is a space created within one powerful physical server. On one such hardware, there can be several separate virtual servers that share the processing power of the processor, memory and disk capacity. However, they are separated using virtualization software while maintaining full security. Virtual servers can perform many functions, but are popular in web hosting environments.
How they work
Among the most proven hypervisor software are undoubtedly VMware vSphere and Microsoft Hyper-V. Using a hypervisor, a physical server is divided into several virtual servers. You can run server applications and several guest operating systems in a virtual environment. This makes them more cost-effective compared to physical servers.

Virtual servers vs. physical servers
To understand the difference between physical and virtual servers, we’ll break them down in terms of performance, scalability, system recovery, portability, and management.
Portability
For a physical server, migrating from one data center to another can be a risky undertaking. This is because you taiwan phone number data will need to back up the data elsewhere on the disk along with moving and reconfiguring all the other components. Virtual servers are hardware independent and you can switch between them with less risk.
Performance one of the main factors
