The great demand for more secure, reliable services has made virtualization technology increasingly popular in the web hosting industry.  While many customers are not ready to handle the costs and responsibility that comes along with a dedicated server, more are discovering that the shared hosting platform isn’t necessarily the best choice for mission-critical operations.  VDS is the latest in virtualization, a technology that offers more control than shared hosting and the power of a dedicated server at a fraction of the cost.

What is a VDS?

Short for Virtual Dedicated Server (VDS), a VDS is created by virtualization software that partitions a single physical server into multiple isolated servers.  The result is a powerful platform that gives you the enhanced security of a dedicated server at a price that it isn’t too far off from shared hosting.  After being partitioned, a VDS is allocated with its own disk storage and data transfer for added stability.   The server has its own operating system along with isolated web server instances, a mail server and root access for custom software installations. This technology functions in a way that no matter what occurs on another customer’s VDS, it will have absolutely no impact on your environment.   Unlike its virtual counterpart VPS, a VDS is virtually like having the resources of an entire server.

VDS vs Shared Hosting

In a shared hosting arrangement, multiple websites are generally stored in a single directory.

The mere structure makes this a security risk.  With the average setup, shared customers have a dangerous level read and write access, meaning they could possibly access and modify your files. Other issues relate to stability as customers are required to share a variety of critical resources.  This includes the operating system, disk drive, CPU, memory and applications.  Depending on the severity, an error on a single account could force the entire server to run slow or even crash.  With VDS, the servers are completely isolated, giving you a level of privacy that is equivalent to running the server all by yourself.  In a VDS environment, you are completely protected from all the actions of other users hosting on the machine.

On a shared server, performance can still be an issue when no malicious actions or mistakes have been made.  For example, if one customer starts to experience a heavy load of traffic, their excessive bandwidth usage could slow down the entire machine.  This could result in a loss of HTTP requests and ultimately visitors for other customers on the server.  Additionally, the possibility of their being hundreds or thousands of domain owners on a single machine makes shared hosting very susceptible to sluggish performance.  This is especially true when many of them are using memory-hogging applications.

VDS is the perfect alternative to shared hosting as you are assured critical resources and the privacy you need from other customers.  In this environment, you will not have to worry about anyone consuming all the server’s memory and bandwidth or having the ability to view and edit your sensitive files.  The additional stability and security you get with VDS hosting makes it the next best thing to a dedicated server.
