What is the difference between 1 shared vCPU and 1 vCPU?

Aaron Lavers · Jul 4, 2016

Could any one please tell me what is the difference between 1 shared vCPU and 1 vCPU? I saw it in hosting packages but I don't know what they are.

A vCPU is already shared as it's virtual resources. But a shared vCPU, it's maybe a virtual CPU in a virtual machine ? ^^
For me it's an error because vCPU already means "not dedicated".

From your experience, how to know it is a dedicated CPU?

There are some way to dedicated a CPU core for a VPS. But in cloud infrastructure, all resources are shared by clusters or pool and there is nothing dedicated. Even without dedicated vCPU you can have very good performances, but it's not true for all vps providers.

It is possible to find out if a web hosting provider hides this information.

Just use :

Code:

bash <(wget --no-check-certificate -O - [URL]https://raw.github.com/mgutz/vpsbench/master/vpsbench[/URL])

It's a small benchmark tool, and the result will be :

Hosting provider doesn't hide CPU :

Code:

[COLOR=#333333][FONT=Verdana]CPU model: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz[/FONT][/COLOR]

Hosting provider hide CPU :

Code:

For me it should be a mistake (I hope the hosting provider know what is a vCPU ^^) as you can run a virtual server in another virtual server, but there is no reason to do that excepted for a personal usage.
