A virtual private server (or VPS) is created through a process of virtualization, by which a virtual replica of a physical server is created. A VPS is like having access to your own personal server, one with your own allocated number of resources and a pre-installed operating system of your choice. Your ISP can offer managed and unmanaged VPS hosting services, and you might be wondering which is best?
Managed VPS hosting is ideal for technical and non-technical people since the hosting provider is responsible for managing the server including system upgrades and configurations; with a managed control, package you have full control of your server.
Unmanaged VPS hosting is different from managed due to the fact that the hosting provider is responsible for providing you with the VPS server but everything else is up to you to handle including the configuration of the server and its services. As you can see this is not a job for an average user but for a technician.
So before choosing one from your ISP, make sure to choose the one that works best for you.
