Dedicated or VPS, what is the best option?

[Wilby]

Everything depends on the size of VPS available(in terms of both CPU and Memory), I am not sure whether all companies provide cut down "dedicated servers" using VPS technology.

I think the line between VPS and dedicated may get very blurry in the upcoming time, but that’s just my opinion.

I don't think this will happen as a dedicated server offers more features in comparison to a VPS as a VPS is a virtual server which is created on a dedicated server with the help of a virtualization application.

[Pongers]

That's right... even i don't think VPS would ever cope-up with dedicated servers as dedicated Servers are more powerful then VPSs having good processor, hardware and other resources... also dedicated servers are independent having their own identity !!

[Crosby]

This is kinda confusing for me. What makes people say that at times VPS's perform better than a Dedicated server?

I am new to hosting,and was under the impression that we get dedicated resources with a dedicated server while resources of a single physical server are shared in a VPS. It would be thankful of someone can shed some light on this.

Good morning,

Clearly a PC running as a dedicated server will outperform the same spec pc running a number of VPSs, or even just one VPS.

The argument stems from the differences in the spec of the machine hosting the VPSs against the spec of the dedicated PC that you would actually purchase. For example here you can pay between £79 and £375 per month for your dedicated server with Windows.

I have a Hyper V-VPS here with 1GB of RAM, this is guaranteed RAM, so clearly the number of VPSs hosted on this server must be constrained by the amount of RAM within the machine. Is this 5,10 20,50 or 100, we don't actually know?

However if you look at the hard disc allocations and practical RAM limits there appears to be a case for suggesting something in the range of 10-20 VPSs.

Clearly there is the CPU overhead involved in running all these instances of the OS? However is this overhead real, it is reasonable to suggest that the server running the VPSs is very likely to have a faster CPU with more cores than the dedicated server, so do these two items cancel each other out?

The we get back to disc access, again we don't know how many drives there are in the VPS server nor their spec. Clearly this is always going to be the weakest area of a VPS, but again is it that obvious, if most of the sites of the VPS make relatively little database access it becomes less clear, how many of the disc reads can be satisfied by the virtualisation layer from RAM cache and then from each instances of the OS's own caches. A couple of sites that do a lot of database writing will be a disaster.

Then you need to consider that the VPS may have been purchased to allow room for expansion, for example mine is virtually idle at the moment. So if you accept that the VPS server is more powerful than the dedicated server then other users of the VPS server are benefiting from my under usage.

Having proposed this argument I would suggest that with the price difference between dedicated servers and VPSs narrowing VPSs may be on the way out.

Bye

This is true that VPS and dedicated servers are very close to each others, however i dont think that they will come more closer.

Dedicated server hosting was the beginning of the web hosting and later on the other hosting solutions came up. VPS hosting may get more better,however not at the cost of dedicated servers

[Rupert]

I do agree with you, Roger. This is the fact that the dedicated servers are getting cheaper nowadays. This has also affected the VPS prices. Both web hosting solutions have there own importance, Dedicated will always remain at the Master place in the hosting world, and i don't think there are any chances of VPS getting vanished as it was and will always be the second best hosting option.

[MattBarthorpe]

Yes indeed,a VPS is the next best choice to Dedicated Servers.VPS is cheaper,secure and offers an environment similar to that of Dedicated servers.
But,IMO. this may not be the case when Cloud hosting becomes popular.It is supposed to offer 100% uptime plus unlimited resources and ease of upgradation.
