What is the difference between a VPS and a Dedicated server?

The needs of each company differ from case to case, when we discuss Web hosting solutions, for this reason it is important to inform ourselves before making a purchase, so that the choice made is as correct as possible. Large projects that require processing power or extended storage will typically have two solutions available: Dedicated Servers or Virtual Private Servers (VPS).

Dedicated servers are represented by physical equipment in the form of a server that contains components such as: processor, motherboard, hard disk, IO controllers, memory, etc. In most cases, dedicated servers have powerful resources designed to accommodate websites with heavy traffic or in some special situations, it will be used only to run a single application. However, the performance of the dedicated server also comes with some disadvantages, represented by: high cost of acquisition and maintenance, physical portability and last but not least the need for management knowledge, because most dedicated servers are offered without administration from the Web company. If these issues can be overlooked, the dedicated server provides a robust and stable operating experience.

VPSs are essentially virtual servers (or virtual machines in some cases) that emulate the behavior and resources of a physical server. Unlike dedicated servers, where the ownership of the equipment is owned only by one person / entity, VPSs share physical equipment with several users, each of them being isolated from each other. This isolation process is accomplished through a virtualization software called a hypervisor, which manages the physical server's resources to assign them to each virtual machine.
For the vast majority of applications, run and response times will be the same regardless of whether they are running on a dedicated or virtual server.
Considering this aspect together with the ones listed below, the purchase of a VPS is in most cases is recommended compared to the purchase of a dedicated server.
VPS vs. dedicated server benefits:

• More affordable prices through the uniform distribution of computing resources
• It provides much simpler and easier security setup and management
• Virtual machines have a much better, more reliable, and simpler disaster recovery process than a physical server
• Migrating easily from one physical server to another or in virtual environments
