First, it is important to understand what a VPS or virtual private server actually is. Virtual private servers can also be referred to as a virtual root server (VRS) or a virtual dedicated server (VDS). When a virtual private server is referred to as a virtual dedicated server (VDS) it usually indicates that the server does not use burst or shared RAM.

Virtual private servers are servers that are created within a larger shared virtualized environment where each individual server is allocated a dedicated portion of the entire systems overall resources. The system resources reserved (or dedicated) to the server commonly pertain to CPU or processor, RAM (random access memory) and disk (size). These are distributed based on how the host has the entire system configured. Further, virtual private servers may have their IOPS (input/output operations per second) and burstable bandwidth throttled or restricted. Like true dedicated servers, virtual private servers have their own root access where you can customize the virtual server to best meet your specific, individual needs. However, given that there are generally multiple virtual private servers on one given physical server or cluster of servers, storage and bandwidth are shared amongst the other virtual private servers. Virtual private servers are generally a better fit for the less experienced server operators as the server management is simpler and easier to control while dedicated servers are more complicated and better suited to more experienced users. A virtual private server can be viewed as a good compromise between low cost shared hosting and the more expensive and complex dedicated server.

Dedicated server web hosting means you are, in effect, leasing the physical hardware from the web hosting company for your "exclusive" or "dedicated" use. The web hosting company or data center manager takes care of this hardware by having it networked and set-up for use in their data center. When you are hosting on a dedicated server, you are the only client using the systems resources and your data is the only data stored on that physical piece of hardware. Further, in almost every case you will have full control of the server including root access and server administration. Typically, if there are any hardware related issues with the dedicated server, reputable hosting companies will assume this responsibility and also monitor the health of the unit with regard to CPU, fans, memory, and power supplies. Best practise also dictates that any hardware failure that requires replacing or any preventative maintenance is needed, is done at no charge.  It is vital that you find a company that offers only the best customer service to aide in maintaining your dedicated server resulting in the highest "uptime" possible.

Now that we have clearly delineated the differences between virtual private servers and dedicated servers, which option is best for you? In most cases clients who choose the dedicated server option do so for several reasons:

1) Performance - your website may have a higher traffic count and occasionally slowing down when the website is at "peak" use. As a rule of thumb, a dedicated server should be considered for any website received more than 2500 visitors per day or during peak times receives more than 500 visitors per hour. This may vary depending on the amount of data being accessed by your visitors.

2) Security - your data will no longer be "married to" and depend on the conduct of others with whom you share physical server hardware with.

3) Customization and choice - in your dedicated server environment you can choose your operating system, software, web tools, and have full control over your website or websites.

4) Cost - if you evaluate the costs of maintaining multiple sites in a shared environment along with the related space, bandwidth and memory costs, you may find it is more economical to simply have your own dedicated server.

In conclusion, committing to a dedicated server is a major decision that requires careful consideration. In many situations making the jump from a VPS to a dedicated server could result in higher costs but the advantages provided could yield tremendous benefits to your business.
