Thread: What is dedicated VPS?

A dedicated VPS is just another way of saying 'Virtual Private Server'. They are often called VDS as well meaning 'Virtual Dedicated Server'.

And why is virtualization necessarily better than a fully blown dedicated server...?

Abstraction is the first that comes to mind - once you've separated an environment from the underlying hardware it makes it much simpler to upgrade/replace/whatever the underlying hardware without having to mess about with the pre-existing installation.

Some deployments we have seen have a single VM running on a system through a hypervisor, simply because of the hardware abstraction it gives them.

I would call a 'dedicated VPS' a virtual server that has uncontended resources - no oversell on RAM and thick allocation of storage.

Great forum community I should say.

Do you think that dedicated VPS will be better then dedicated server?

Depends on the requirement and the VPS spec. There are many who are merely loading a hypervisor onto a 300 quid server with a pair of software raid or equally shady disks and selling VPSs. There are those with massive Sans and uber servers. If you get the latter you are more likely to get better availability than a cheap dedi (i.e. more PSUs, R10 disks etc) although if you need raw disk bashing, typically even a cheap dedi will outperform a large shared disk array.

You need to define "better" more carefully...
