The Difference Between VDS & VPS
The ovbious answer is one single letter is the thing that separates a VDS and a VPS at first glance, but once you start to dig, it’s really a comparison of apples and oranges.
VDS (Virtual Dedicated Server) vs VPS (Virtual Private Server)
Just the names alone should give you the answer to the question. Why not go for a Virtual Dedicated Server? A VDS essentially a modified Dedicated Server, and a Virtual Private Server is just allotting you a specific amount of space and power on a server, that still has be be shared through the entire server. Hyper-V Virtual Dedicated Servers have major advantages for companies over the traditional VPS solution. The allotments of your VDS solution are 100% dedicated to your account and your account only. The reason Hyper-V services aren't more popular is because the hosting company isn't able to oversell their systems. They are no longer able to jam 50 instances on a single server when you logically should only have a handful of instances on each node (server.)
Virtual Private Servers are usually offered on a stand alone server where your contingency plan doesn't exist. Yes, there are some companies out there that will have a clustered solution and have a larger RAID array for your sites, but do you want to figure this out after your site goes down and doesn't come back online a few hours later? A VPS also has the chance of Bottlenecking sometimes. This occurs when applications and software of other clients on the server utilize the servers resources at the same time. Because there is no real way to separate the VPS clients into their own systems life Hyper-VDS, you will have that slowed server affect during busy hours.
The newer Hyper-V R2 architecture has a much more efficient layout that does not allow the VMs (Virtual Machines) to share/steal services from one another. This makes it a strong choice for both production and development environments, as disaster recovery and server consolidation are supremely efficient.
All that being said, the Virtual Hosting environment is one that is much more agile and reliable compared to the stand alone dedicated server solution. The customer is able to ramp up to the amount of space, memory, and processing power they need. The Hyper-V VDS solution truly grows with the customer's needs and never gives you wasted services which always equals wasted fees.
Really Though, How Does it Work...
 The easiest and most efficient way to explain Windows Hyper-V is to show you with an image. The above image shows you exactly what we see at our data center. You have several servers that are setup with Windows Server 2008 DataCenter Edition, and they are clustered together. They all shared a centralized SAN solution that is running RAID 10 with hot swap enabled drives. With this solution, GeekHosting.com can move your instance to any Node (Hyper V Server) on the network, and in case of a complete failure of one of those servers, the Live Migration Tool automatically gets your Hyper-VDS instance to a healthy Node without any major outages and any upset customers. Its really a perfect fit for GeekHosting.com and our customers.
