What that is VPS?

**Ondu** · 03-19-2009, 07:44 AM

I wonder why that is called VPS here
http://pivotalweb.com/valueplans.php
Value-4
Isn't that full dedicated server? What is the difference in calling only?

A VPS is a Virtual Private Server.
A virtual machine, like in vmware, xen or virtualPc that holds your datas.

The difference, is that you still share 1 physical machine with other peoples.
Like in shared hosting, if the server is hosting 100 VPS, the VPS will be slow.

A dedicated server is 1 physical machine, where only you use it.

I know. thanks, but why that almost dedicated server is called vps?

**chrishirst** · 03-19-2009, 09:21 AM

because it's not dedicated.

Another thing you have look at is you are probably not receiving 2 CPU cores. You probably are given the ability to use two threads for processing. Its not like a hybrid where you are getting a dedicated core or two. They cost alot more.

All that for $2 a month, I wonder how many accounts they ram on to one server?

Dedicated server: whole phisical server is yours
VPS you have part of the server
Sometimes part of the the one server is larger then the whole server instead

Be careful. Not all VPS are created equal.

I expect a VPS to be identical to server in all respects except for the fact that it's running as one instance among many on a server. I expect root access and to be able to install and run anything (within reason given the constraints of the VPS) on it. I expect the ability to reinstall the OS on demand and ideally a choice of distributions.

Some ISPs offer "VPS" products that are best described as souped up shared hosting packages. Check what you're actually getting.

It really depends how the VPS is created. There may be certain modules or settings missing - that may stop you from installing such things as firewalls.

Granted. This I consider acceptable, limitations are usually networking or process related. I'm not a virtualization expert but I can buy that it has some limitations on what you can do networking wise.

What I don't accept is providing a system with restricted ssh access (e.g. jailshell), restrictions on how the configuration is done, requiring maintenance via a panel and then still calling it a "VPS". That' just not quite P enough for me.

I've run enough VPS' to be able to spot the difference.

//OFF Topic
Andrei, maybe you know the answer to this: Is a VPS able to run an IPSEC tunnel or are there networking issues prevent this and require a dedicated server?

(I know I should be posting this in a separate thread, but I'm new here (been lurking) so I still need to get my Post count> 15, then I'll do that.

Thanks

DON'T GO WITH PIVOTAL WEB !! I've been a former customer of them and they suck big time ! This is a company run by some kids from their dad's computer or something, they don't have a clue what they are doing... seriously..

**$alesman** · 03-22-2009, 01:49 PM

Be careful a good vps will be 20$ a month if its cheaper like 2-3$ then its horriably oversold and then the people get more access then regular server = horriably slow and insecure server. I would stronly advise you against it.

That is right. But I suppose to state that you need at least try that.
If you need to host something oversized do not expect you will be allowed to do on the small package

I do not intend to discuss companies, rather mention that vps also have pluses and minuses as any hosting solution.

On the plus side of vps there's fliexibility and upgradeability, they are less costlier than dedicated. If your host provides mamangement and firewall is included there should be no problems with security as well.

However, there are some risks of using vps server, say if all the tenants of the server use the same IP address, if your neighbours are unscrupulous, there are chances that your site may suffer. Ifany software components are shared by vps users, this may lead to inability to configure them independently of other clients.

VPS have a sence of the dedicate sever and that help people to have sence of the independence

IPSEC via software such as freeswan requires kernel support, and therefore whether or not it's possible within the context of a VPS depends on the virtualisation technology/approach used. Hypervisor based virtualisation (e.g VMware) or paravirtualisation (e.g. Xen) will give you the potential of running your own kernel.

Container based virtualisation (e.g. Virtuozzo) means that you share a common kernel with the host node, and therefore there is (pretty much) no way to run freeswan on a Virtuozzo VPS.

However, you should be able to run OpenVPN pretty much anywhere, and that is (arguably, and of course depending on the scenario) often a better choice.

Hope that helps...
