I know this question is lame, and have been asked many time before. I do have the understanding about the difference between shared and dedicated server. But what exactly is the difference between dedicated and cloud server ? In both case we have dedicated resources. In both case is a virtual machine. the what is the difference ?

The word cloud is overused and so diluted now.
Think of cloud as a VPS with hourly billing. If cloud were actually "cloud" it'd be more expensive than $5 per month.
Dedicated is still the same.

There're so many different definitions of cloud. My definition means automatic failover with floating IP's, SAN storage (not local), self-healing, and much more.
Wikipedia: https://en.wikipedia.org/wiki/Cloud_computing#Characteristics

Depends on who you ask, and what their definition is. It's being overused and becoming yet another buzz word.

I agree with localnode, seems that every provider just tosses the word cloud at any "scalable" product.

Real Cloud hosting is more expensive than a dedicated server, since the cost of operating a cloud infrastructe are higher than those of a dedicated server.

At this point "Cloud" does not mean much any more. In technical terms a cloud is a redundant set of servers which your VPS sits on top of.

Everything is marketed as cloud these days, it's all just advertising.

So you mean true cloud hosting is the one which are giving auto scaling feature like kyup ?

Yes thats true.

But how that is achieved is a long story, there are some operating systems which let you do this. For example openstack.

Openstack is an layer which will make your virtual machine looks like that it has been allocated resources from only one physical machine, but in reality there may be multiple physical machines below it.

Now everything is managed by openstack, including network, storage and fail over.

Auto scaling and dynamic billing based on usage is a feature of Cloud technology yes but it does not define it.

The term Cloud cannot easily be defined these days even online office apps like office 365 are sold as "cloud" apps. Anything online now seems to be "cloud"

From a technical computer standpoint a cloud is a bunch of servers linked together to provide performance and redundancy, that's all cloud is.

As said by everyone, cloud definition is more complicated. True cloud is more expensive and the features offered by it are superior. All these so called cloud vpses are just virtual machines on a physical server which resemble like cloud infrastructure. But in reality true cloud is not offered by anyone who advertises as $5/ mo or $20 / mo.

True cloud is more than what people speak and debate about, and most people just want to win or make their favorite provider win in debates. Instead of discussing about what does or what should a cloud infrastructure should do.

I laugh out when people sell shared servers as cloud in some parts of my country. Unfortunately they are deep rooted in market, so customers does not listen if we say that XYZ company is not offering cloud. Its just a shared web hosting or vps or even worse old baremetal server refurbished and re-marketed as cloud.

Hi there, new around here.

So, what I have read so far. Cloud hosting seems to be more efficient, but more expensive as well.

Dedicated hosting costs less.

Now, since the cloud has hourly billing, how much could it scale from dedicated hosting.

Are the price ranges somewhat similar? What would you advise?

I somehow think that dedicated hosting is still the best bet if you had a decent company which would host for you.

Personally I don't think that billing period is relevant when defining 'cloud' from the technological point of view, more important is the nature of high availability which you can achieve when everything is running on multiple servers which work as a seamless 'pool' of resources. This also provides other advantages like better scalability and more versatile deployment. The last one lets providers offer resources on hourly basis because it's so easy and fast to deploy and manage instances as needed.
