In order to appreciate the beauty of Virtual Dedicated Hosting, it helps to understand the alternatives – "shared" web hosting and “real” dedicated hosting.So which one is best?
Shared web hosting makes it possible for hundreds or even thousands of users to host their sites very cost effectively. However, there are a few drawbacks.
Because many web sites are hosted on the same physical server each site must share that server’s resources. These resources include bandwidth, disk space, memory, and CPU usage to name a few. The need to share resources is rarely a problem for small and medium size web sites.
Real dedicated web hosting, on the other hand, solves all the problems with shared web hosting, but at a significant cost. With real dedicated hosting we have exclusive use of an entire server: all the memory, all the disk space, all the CPU horsepower.
Therefore, no other web sites’ problems, glitches, or whatever, will have any effect on our web site. we have total control over the server, its resources, and its administrative functions.
A web hosting solution but it isn’t cheap. We have to pay for an entire server with no one else to share common expenses. So, typically, a “real” dedicated hosting plan will cost a minimum of some dollars per month and goes up from there. And, unless we opt for managed hosting which is even more expensive, we have to do all the technical server administration ourself.
Most web site owners don’t need total control of their servers as they simply want to run their businesses. They have neither the interest nor the ability to perform all the technical tasks associated with a fully dedicated server and are more than happy to let their shared web hosting provider handle them.
When an online business begins to ramp up its transaction volumes, expand its product line to a large number of online offerings, or simply requires more control over its environment, there is a very cost effective alternative to a fully dedicated server.
Virtual dedicated hosting, also known as virtual dedicated server, or VDS, hosting, is the term for a physical server which, by means of software, has been partitioned into a number of virtual machines operating independently of each other as if they were standalone dedicated servers.
The big advantage of Virtual Dedicated Server over a fully dedicated server is cost. Typically priced at less than one fourth the cost of full dedicated hosting, VDS hosting provides nearly all the same benifits. And compared to a shared web hosting plan, VDS is only slightly more expensive providing an excellent balance of economy and control.
With a VrtualDedicatedServer all physical resources such as memory, disk space, and the CPU continue to be shared, but each virtual server operates in a fully independent manner.
The main advantage of a VirtualDedicatedServer is that each administrator maintains control at the root directory level of his or her own virtual server. Access at this level permits the web site owners to do a lot of neat things.
