Hosting can be broken down into three general types: shared hosting, virtual private servers (VPS), and dedicated servers. Shared hosting plans are the lowest tier of web hosting in terms of performance, price and customizability, which leaves those with serious hosting needs to look into VPS or dedicated hosting options. There are many different options available to customers seeking VPS and hosting solutions, which creates a somewhat blurry line between the two general types of hosting solutions.
Get Dedicated!
Dedicated servers are often the fastest and most powerful choices available, though some of the high-end VPS options can give the lower performing dedicated servers a run for their money. The point is that dedicated servers really occupy the upper strata of the web hosting performance spectrum, and are typically priced accordingly. There are a few benefits to selecting dedicated servers, some of which may or may not be available on some VPS solutions.
One of the major attractions of a dedicated server is that it is generally completely under the control of the customer. Therefore, it can be rebooted when needed and can also be completely customized in terms of the software it runs. Customized software can be very important for a number of reasons, but even if the software is off-the-shelf, not all VPS and shared-web providers give their customers carte blanche to install and run additional software. In fact, most shared hosting providers have limits to what can be installed in terms of resource allocation, and VPS providers may not always give 100% control of their virtual modules to customers. In short, dedicated servers are usually able to run anything that their hardware can handle.
That hardware is another attraction to dedicated hosting services. VPS solutions share the resources of a single computer in most cases, but dedicated servers put all of the resources at the disposal of a single customer. Memory, hard drive storage capacity, processing power, and network access are all 100% dedicated to a single customer instead of shared amongst multiple VPS customers or dozens of shared web hosting customers. The result is that performance should be very predictable, which is very important for those who are planning on hosting e-commerce solutions or planning on monetizing their website(s) in other ways.
A Primer on Virtual Private Servers
Virtual private servers are a little harder to get one’s head around than dedicated servers, mainly because dedicated servers are something that nearly everyone can identify with: a computer. Virtual private servers are different from dedicated servers in that instead of running one hosting account on one computer/server, virtual private servers share a single server. This may cause one to wonder what the difference is between a VPS solution and a shared web host. This is a fair enough question, and there may be variations to the answer depending on who one chooses to ask.
The most basic answer is that shared web hosting plans are mostly offering unlimited bandwidth and often unlimited storage, but there is no promise in regards to the amount of CPU power and/or memory available in most cases. Additionally, there are often restrictions on installing and running CPU/memory intensive modules or software, as hosts may view such software as very disruptive to the other accounts on their server(s). VPS solutions almost always offer a minimum allocation of resources that is guaranteed 24/7, and some even offer ‘burst’ resources that may be available whenever the load on the server allows for it.
The other thing that separates VPS solutions from shared web hosting is the amount of control customers will have over their hosting plan. Does the server need to be rebooted? No problems, just flip the digital on-off switch from the control panel and wait a few seconds. Want to install a resource-hungry software package without looking through approved-lists? That is also possible with most VPS solutions, but not with all. The old expression advises that it is not possible to get something for nothing, so be wary of making assumptions about this level of control on the cheapest of VPS packages on the market.
VPS: Terminology to Consider
Having minimal hardware allocated to web serving sounds great, but there is a catch: not all of the hardware specified is necessary as simple or straightforward as it might initially seem. For example, just because a VPS package claims to offer 1 GHz of CPU performance and 384 MB of memory, does not necessarily mean that either the memory or CPU allocation is not split into multiple chunks. This might be important for those who plan on running software or processes that are high-performance but poorly threaded. For the purpose of setting up blogs, however, having virtual ‘pieces’ of a different CPUs and memory contribute to making a single ‘chunk’ or ‘node’ of memory/CPU performance is probably not a serious issue due to the low-intensity of the task at hand.
The bottom line is that consumers shopping for VPS packages need to ask questions about the hardware instead of making assumptions based on what they see. It also pays to ask whether it is possible to permanently and/or temporarily upgrade a VPS account without downtime if one plans on growing their online presence. Remember: downtime is the enemy if all websites, especially those that are generating money or anchoring a presence in cyberspace.
VPS In the Clouds
One of the latest innovations in the VPS market is the use of cloud-VPS solutions. Cloud VPS solutions make multiple-redundant copies of entire websites in case one server were to be taken offline unexpectedly. VPS NET (vps.net) is a great example of a cloud-VPS solution provider that can cost between $20 and $234 per month, but other top-tier providers offer great plans as well. Specific examples include MediaTemple ($50-$150 per month), and HostGator ($19.95-$209.95 per month).
How to Decide.
Finding the right balance between price and performance is always a challenge, but remember that one usually gets what they pay for. Sadly, sometimes people get less than they pay for too, so be careful when assuming that money alone is a good measure of quality and capacity. Compatibility is also important, and thus sticking with top tier hosts with established names is probably a good idea for those with serious hosting needs.
The distinction between VPS and dedicated servers can get blurry at the high-end of the VPS scale and the low-end of the dedicated server scale. If steady hardware performance and ultimate control of software is important, then dedicated servers are probably a wise choice. MidPhase has dedicated server packages that start at $89.95 per month and can scale to $349.95 without customization. There are less expensive options out there, including ServerPronto, but remember the earlier advice about getting what one pays for. That being said, deals such as ServerPronto’s limited-availability dedicated server for $4.95 per month are amazing, and an affordable way to learn more about dedicated hosting and grow a site or collection of sites until they are ready for some more serious hardware.

Great article, very informative! However, if say you’re getting into basic video streaming (Http based using something like xMoov), would you recommend dedicated or VPS?
Ah.. still can’t decide to use VPS or Dedicated servers, as the dedicated server need to manager myslef, and most VPS is managed..
In most cases, a VPS can actually be slower than shared hosting. I think that a dedicated server running 20 instances of Plesk would be much slower than a dedicated server running 1 instance of Plesk and hosting 20 websites. There are some high-quality and cheap dedicated servers out there for $100 or less. If one has a successful website and resources, I would recommend going directly to a dedicated server instead of a “VPS.”
Hi,
In general I would say a VPS performs a lot better, since all hardware behind it, is from a much higher class. For example the disk array used to store the VPS are HUGE and redundant. Meaning they can handle a lot more iops than an average dedicated server. To get the same performance and redundancy as with VPS’es, the investment would be huge!
I don’t see where you have no freedom with a VPS compared to a dedictated as well. I would say you have more freedom. One can easily extend or downgrade a VPS anytime. Which allows great flexibility at any time and is costsaving.
I’d say, if not convinced, try it yourself ;)
It is definitely right, All this features which is shared web hosting, virtual web hosting, dedicated server hosting can provide a lot of value and benefits for businesses and website owners.
