If you have a site that works with different servers, you have probably come across VDS or dedicated virtual servers and VPS or private virtual servers. You may be familiar with these servers. But what are these servers really like and how are they different from other servers?! Maybe you are still hesitating between choosing a VDS server and a VPS server! In order to get familiar with dedicated and private virtual servers and to understand the use of VPS and also to see if you should use VDS or VPS for your website, continue reading this article.
What is VDS or dedicated virtual server?
VDS stands for Virtual Dedicated Server. VDS server is actually a part of a dedicated but virtual server. VDS servers are also known as semi-dedicated servers. Also, this server is built with the help of virtualization software that divides a physical server into several servers, which you can use to access a strong platform with high security.
After the server is divided into separate parts, each VDS will become a data transfer and storage space, and each VDS has a dedicated system along with a dedicated server and root access to install custom software. Today, VDS has found its place among the vocabulary of the information technology field, and in the VDS service, physical server resources such as RAM and CPU are specifically set aside. In a dedicated virtual server, each virtual server has an independent system that can be rebooted.
Due to the fact that the provision of dedicated services is expensive and difficult to manage, virtual servers can be considered suitable options. Also, if the shared service is not suitable for your purpose, choosing a virtual server will be a good option.

What is the use of a dedicated virtual server?
VDS are suitable for users of websites that have high traffic or require more functionality. Because the semi-dedicated server or VDS has higher quality and faster speed than the normal virtual server, you can count on these servers in many cases.
Also, in many cases, due to the resources and technical facilities of a dedicated server, there is no difference between a semi-dedicated server and a dedicated server. It can only be said that a semi-dedicated server is more affordable than a dedicated server. So it is wiser to choose the cheaper option. The hardware power of the semi-dedicated servers is very similar to the dedicated server, and there are processing resources (kernel) on the servers, just like the dedicated server.
The VDS server has increased the security of users due to having a non-shared hard drive and RAM, and there are no problems such as the failure or poor performance of other accounts; Because the servers are completely separate. Using a non-shared hard drive in VDS servers, in addition to not having destructive problems, increases the speed of use and does not slow down other accounts like shared hosting.
What is VPS or Private Virtual Server?
VPS is a virtual server and an abbreviation of the English term Virtual Private Server. VPS is similar to a dedicated server, except that several virtual servers are placed on one physical server, and you can configure your desired parts and customize it according to your needs. To provide VPS, the server manager can divide the main server into several parts by providing a dedicated server and a virtualizer under the server and adjust and customize each part based on personal needs or customer needs.
VPS servers share the same RAM and hard drive as VDS, and this makes them not only have high security, but also eliminates your worry about reducing server speed. You can also easily change the server configuration and install your desired programs by having root or administrator access. This feature is not available on dedicated servers!
What are the limitations of VPS?
Although VPS has many features and helps you many times, in some cases, using these servers also brings limitations. These limitations include:
- Ability to make settings in system files
- Low level access to equipment
- In a physical environment, several isolated copies work simultaneously with one core for themselves. The VPS server has made it possible to provide customers with quality services and a balanced price.
Comparison between VDS and VPS
It can be said that VDS has more utility, security and scalability than VPS. But when it comes to the price of these servers, the situation is different. Because the number of virtual servers that can be defined on VPS is more than that of VDS, the companies providing this service demand a higher price from the customer.
VDS is more suitable for commercial sites or large sites; Because the traffic of these sites is increasing day by day and they need higher efficiency and speed. Note that in both VDS and VPS there is full access to the server and you can apply the settings you want to the server.
VDS is a virtual server with all the features of a VPS. But it also has a decoupled version of the kernel that is provided for personal use. Therefore, the user has the ability to edit it. Also, VDS hosting is compatible with Windows and this is a good point for this server.
VDS and VPS competition in different fields
Whether you choose VDS or VPS depends on your needs and expectations from your server. In some capabilities, VDS outperforms VPS, and in others, the opposite is true. So it’s important which feature is most important to you.
The use of a dedicated kernel is the most important advantage of the VDS server, which provides a completely independent environment to its users. For this reason, the security and capability of VDS is much more than VPS. On the other hand, VPS is a step up from shared services and provides users with higher stability and power. It is also newer than VDS in terms of virtualization technology, which has made it more popular than VDS.
On the other hand, due to the exclusiveness of the resources, no matter how much the VDS on the dedicated server use their resources, usually the performance and quality of your server will not drop significantly, and this issue is considered an advantage of VDS compared to the VPS server.
Each server has positive and negative features. Your expectation from the server you want and the capabilities that your work needs will determine what kind of server you will lean towards. This is also the case with VDS and VPS servers. In general, it can be said that in terms of the price of the server, the difference in the level of exclusiveness of the resources causes the price difference between VDS and VPS. Using a VDS server costs you more, but if you don’t use a lot of resources, choosing a VPS is more cost-effective.
If you have a highly visited site or application, or server stability is particularly important to you, VDS can be a good choice for you. Therefore, by using VDS, you can have a separate dedicated environment with more functionality and security than VPS. After choosing the server, list your needs and expectations from the server, take a look at your budget and finalize your decision to choose the server!
