VPS vs. VDS: What is the difference between VPS and VDS

With the development of the Internet, more and more businesses need servers to host their websites, manage office tasks, or run online trades. However, owning or renting physical servers is still unaffordable for most small businesses. In this situation, server virtualization technology makes it possible to let lots of people share limited hardware resources at a relatively low cost. And hosting service providers have a chance to benefit from virtual servers’ management.

You have may learn the differences between some typical virtualization services from our previous blogs: VPS Vs Cloud Server: Which Hosting Should I Choose – DBM Blog (databasemart.com) , VPS vs VPN: What is the Differences Between VPS and VPN? – DBM Blog (databasemart.com), and You searched for VPS – DBM Blog (databasemart.com).

Here we will talk about a new kind of hosting: VDS (virtual dedicated server) and its difference from VPS (virtual private server).

What is VPS?

VPS, a virtual private server, is created in a shared physical by mimicking a dedicated server environment, and it has its own operating system. It allows users to access each VPS with root permission and enjoy private resources. Usually, a provider will create 30-60 VPS in a physical server based on a Hypervisor or OpenVZ virtualization technology. That means fully resource occupied VPSs will affect other VPS’ performance. 

VPS has the most benefits as a dedicated server at a lower price. Compared with a shared plan, VPS is more secure and controllable due to private resources.

What is VDS?

People create multiple VDS, virtual dedicated servers, in a physical server as well. VPS and VDS have very similar features but use different virtualization methods. The different virtualization methods make VDS work more like a managed dedicated server. Unlike VPS, although there will be several VDS hosted on a physical server, other VDS’ resource usage will not affect your VDS’ performance. For example, if 4 VDS divide a physical server’s resource (one CPU, 16GB memory, and 100GB disk), then, one VDS user can only use up to 1/4 CPU, 4 GB memory, and 20GB disk. VDS does not share the same resource of a mother host server; therefore, it does not offer any multi-tenant environment. Additionally, you can get bandwidth as a dedicated component if you opt for bandwidth-intensive tasks, such as streaming or file sharing.

Difference between VPS and VDS

As a whole, VPS and VDS are very similar when used, but there are still many differences between them.



  • VPS depends on OS-level virtualization.
  • Dozens of VPSs will share the resource of hosting physical server, including the core of the mother operating system, the CPU, memory, storage, and bandwidth of the main server.
  • VPS’ virtualization method is efficient and compatible with most tasks and does not require extensive changes to the OS.
  • A parent server runs several VPS instances.
  • It’s more cost-effective.
  • It offers most features of a dedicated server, but still less functionality than VDS.
  • It offers some scalability and predominant convenience.   
  • It’s managed and controlled by OS. 
  • It’s a good choice for people who run low load task, such as office applications, deployment of small e-commerce, corporate sites, etc.             
  • VDS depends on the paravirtualization method.
  • Both the mother OS and VMs have separate cores. That means a VDS user will get the assigned dedicated   computing power or a certain number of physical CPU cores permanently.
  • VDS’ virtualization method requires OS changes. It’s best to choose the Linux OS which is open-source.
  • A VDS instance takes up the entire server.
  • It’s more expensive, but more cost-effective than dedicated servers.
  • Higher-level functionality than VPS
  • It does not offer scalability and predominant convenience. 
  • Its operation is managed and controlled by server hardware.
  • It’s a good choice for people who runs high load tasks, such as streaming video and audio apps, game servers, large e-commerce projects, etc.

VPS and VDS' pros and cons

Both VPS and VDS try mimicking a dedicated server environment by the virtualization technology. However, each of them has some unique or common advantages and disadvantages. Let’s see the lists as follows:


  • VPS is easy, flexible, convenient to use, and much fits common people. 
  • VPS/VDS supports almost all web apps running.
  • Easily reboot VPS/VDS independently.
  • VPS is cheaper than a dedicated server or VDS.
  • Users can customize most VPS plans based on their needs.
  • As dozens of VPSs share a physical server’s resource, a VPS may not be able to use the assigned amount of RAM or CPU. If every VPS is assigned with 16GB memory, when most VPSs occupy more than 10 GB, then, all VPS performance will be affected.


  • Support almost all web apps running.
  • Each VDS on a physical server can use the total resources assigned.
  • The average price is higher than VPS.
  • VDS needs the users to be trained with advanced technological skills. 
  • Support customization, but has many limitations.
  • VDS is not scalable.

Which service to choose

If you ask me which service you should choose between VPS and VDS, I may not be able to give you a direct answer. Your choice completely bases on your business’s scales, task types, and technological skills level.

For unskilled users who have just begun their business, people usually recommend VPS as VPS’ scalability can match users’ frequent requirements changes.

Senior technical specialists may have known how many resources they needed or want a server to run some high-load tasks. In this situation, VDS is much better than VPS as other users on the same physical server will not disturb your VDS.

Hope this article helps you understand more about the VPS and VDS hosting services. Database Mart provides many kinds of hosting services, including VPS and dedicated servers. Dedicated servers have the whole advantages that a VPS or VDS has. You can consider it as an alternative option for your business hosting.
