What is the Difference between VPS and VDS?
If you, like most online business owners, want to launch your own website and need an affordable yet powerful server, it is natural to buy a virtual server. This is where you unintentionally find yourself between VPS and VDS, and because you are not familiar with the main difference between VPS and VDS, you cannot make a decisive decision on this matter.
The main difference between VPS and VDS is summed up in the way resources are structured and divided. In this way, VDS resources are considered exclusive and fixed, and by purchasing VDS, you own a dedicated virtual server that no other user can access. VPS users also have access to these dedicated resources, but the load or heavy traffic of neighboring VPS can reduce the stability or performance of your VPS.
Do not worry! We are here to introduce you to the differences between VPS and VDS. Understanding the differences between these two servers allows you to quickly decide whether VPS or VDS is the right choice for your business.
Of course, this same structure or different division has caused other differences that we will examine in detail in this article. So we recommend not to miss the continuation of the article:
What is VPS?
VPS stands for Virtual Private Server and is a virtual computer created from a physical server’s virtual division of resources. Physical or dedicated server resources are created using technologies related to virtualization, and users can pay for a virtual version resulting from the division of a physical server and own a private server with specified capabilities.
If we want to explain this issue with an example from the real world, the building and the apartments are the most accessible and understandable examples.
The physical server is like a large and tall building. As this building is divided into separate and private apartments, the virtual server is also considered different from the remote parts of the physical server. Virtualization technology is used to separate physical server hardware into virtual servers, and because of this virtual separation, users can access their private or exclusive resources within a shared environment.
Every virtual server user gets the resources he needs by paying a small fee (compared to buying a physical server) to use these resources in the way he wants and have his privacy.
But just as resources such as electricity, water, elevators, corridors, or parking are shared in a building, virtual server resources are related to the entire physical server. If the server load is excessive, the performance of the virtual servers on that server may be affected. Be disturbed.
You might think shared hosting also has this problem, so what is the difference between VPS and shared hosting?
Besides the main difference between VPS and VDS, virtual servers and shared hosting also have many differences. A virtual server comes from the virtual division of a powerful physical server, which will perform much better than a shared host that hosts several websites and all use the same resources simultaneously.
A virtual server is an intermediary between shared hosting and a dedicated server regarding performance, services, and access level. It means that it has many advantages compared to shared hosting. Still, it also has more limitations than a dedicated server, which, in most cases, these limitations can be ignored in front of its performance and cost-effectiveness.
By purchasing a VPS, users will have an isolated server with hardware and software features that they can have root access to if needed and perform tasks such as installing desired software, setting up protocols, etc.
Applications of VPS
- Hosting websites with medium to relatively high traffic
- Software development and testing
- Setting up online stores
- Setting up the email server
- Create a server for an online game
- Implementation of personal projects
- Data management and backup
- …
What is VDS?
So far, we have understood that VPS results from the virtual division of hardware resources of a powerful physical server. Still, before examining the main difference between VPS and VDS, it is better to know VDS or Virtual Dedicated Server well.
As you know, a dedicated server is a powerful computer with resources available to only one user, and other users, whether virtual or real, do not have access to it. Like a private house or villa where all the resources and facilities are available and you don’t have to share them with others.
VDS, which stands for Virtual Dedicated Server, is an intermediary between VPS and a dedicated server, which is superior to VPS in terms of scalability, performance, and efficiency. Still, it also faces limitations compared to a dedicated server.
Suppose we do not consider the main difference between VPS and VDS. In that case, VDS and VPS have many similarities, their main similarity is that both result from virtualization technology. Still, there is no sharing of resources in VDS.
In general, the hardware resources of each virtual private server user, such as disk space, CPU, memory, operating system, and bandwidth, are fixed and do not change. However, these resources are accessed remotely and through the Internet. So, by purchasing VDS, you will own a semi-dedicated server, and all of its resources will be available to you virtually.
The main reason why prominent and high-traffic websites use VDS for their hosting is that the performance of neighboring servers does not have a negative or positive effect on the performance of VDS, and although they have full access to their resources, whenever they realize that their server is capable of It does not have to handle traffic and requests, they can take action to upgrade their dedicated virtual server plan. The same advantage that virtual server users also enjoy and increases the flexibility of the hardware infrastructure against the upcoming conditions.
Although in no way can one deny the hardware capabilities and power of a dedicated server, you can own a server with hardware capabilities by paying less. At the same time, flexibility is one of the advantages of buying a virtual server that only VPS and VDS users know about.
Applications of VDS
- Hosting large sites with high-traffic volumes
- Software development and testing
- Secure management of sensitive and confidential data
- Setting up the email server
- Setting up a server for heavy and complex games
- Implementation of simple to complex projects
- …
Now that we are familiar with these virtual servers, it is time to examine the ten main differences between VDS and VPS so that you can have a more informed and, at the same time, more straightforward decision-making process.
Comparison of VPS and VDS and ten main differences between VDS and VPS
Although these two virtual servers are similar in many aspects, knowing their differences can make the choice more accessible for you. So, let’s get started:
1. Virtualization method
VPS is created through the operating system-level virtualization method. In this method, all virtual servers run under the format of a container. In addition to RAM, processor, and bandwidth, the core of the central server’s operating system is shared among themselves. You may look at this issue from the point of view of limitation, but this division or sharing does not make any significant changes in the operating system, and virtual servers can handle most tasks well.
OpenVZ technology is one of the operating system-level virtualization methods whose speed and high performance are its most important advantages, and this technology is mainly used to create VPS.
VDS is also the result of the Paravirtualization method. This method requires a hypervisor that runs in a layer above the operating system and manages to allocate server resources between virtual servers.
In this virtualization method, the operating system’s kernel is not shared, and each server can have a different seed. The customization level of this method is higher than the active system-level method. KVM is one of the popular methods of virtualization in the form of Paravirtualization, which is used to create VDSs.
Of course, this primary difference between a virtual server and a dedicated virtual server is one of the things that the user overlooks because both methods bring the same result for the user.
2. The degree of specificity of resources
VPS and VDS hardware resources are considered separately, but their performance differs during peak load or traffic.
In this way, the VPS has specific resources and only uses them to handle its requests, but when one or more adjacent virtual servers are active and face a heavy load, the performance of your VPS is also affected. It will take, and the main reason is the shared resources of all VPSs in the physical server.
But by purchasing VDS, you become the owner of a virtual server with proven resources that neither you can violate your rights nor virtual servers can enter your privacy when faced with a heavy load. In general, VDS isolation is stricter than VPS, and since you will not give your resources to other users when needed, it makes your server performance stable.
3. Structure
The structure of both servers starts from a physical or dedicated server. After virtualization methods are implemented, VDS and VPS servers are created.
Look at the figure below so that the structure of these two virtual servers is more concrete for you:
Each VDS is a virtual semi-dedicated server, and all resources such as memory, hard drive, processor, and operating system are only at its disposal and continue to operate separately and independently.
But VPS is almost shared mode. In this way, as long as all servers are satisfied with their right and have not exceeded the limit of resources assigned to them, everything is in order, and there is no sharing. But when one of the VPS in the physical server faces excessive load and traffic, it can benefit from the resources of the adjacent servers in a shared manner, and this causes the performance of the adjoining server to drop.
4. The degree of influence of the performance of adjacent virtual servers
Some VPS providers, because most users do not use all their resources, try to create many virtual copies on a server and get more profit, but this causes when using all the server’s resources at the same time, the amount of user demand is greater than the actual capacity of the server, and this causes the performance of all servers to drop.
This is where a VDS advantage becomes more prominent. Although most VPS providers try to be prepared for any eventuality and do the necessary work to handle requests or sudden changes, the main advantage of VDS is that the amount of traffic or load of neighboring VDS does not affect the performance of your VDS. Because the resources of the dedicated virtual server are fixed, no user can access the help of another user’s virtual server.
Even if you are at the peak of traffic and use your server’s hardware resources, you still cannot get help from another nearby server and share its resources. Also, an outage on your VDS server would only hurt you, and none of your nearby VDSs would be affected by your server or website outages.
5. Control and access
In this primary difference between VPS and VDS, the VDS server takes a step forward because its control and access are more complete than the virtual server. VDS users can access the server, apply settings, and install and manage various programs and applications. Servers are more accessible.
The main reason for this is the virtualization method and the control level of the physical server. In this way, in VPS, the operating system performs almost all the necessary operations, and the user does not have full access to features and resources, but in VDS. However, the hardware is responsible for controlling the process, users have full access to features and resources. They can apply the necessary changes and adjustments.
Despite all this, VPS users still have the necessary access despite a series of restrictions, and these restrictions are meant to create more security on the virtual server.
6. Performance and stability
It is up to you to decide on the power of VPS or VDS resources based on your business needs. So, if you have made the right choice, both servers can provide you with the expected performance and stability, but this is true as long as the server is not overloaded.
When the neighboring servers face overload, the virtual server faces the possibility of failure and slowness, and this is due to the sharing of resources. On the other hand, because VDS has guaranteed and stable resources, no matter how much the nearby servers have excessive or destructive activity, your VDS will continue to function and be tough as before.
So VPS and VDS both can bring you to the performance and stability you want. Still, when the adjacent virtual servers are overloaded, VPS has no guarantee to maintain performance and stability, but VDS has no impact on its activity. continues
7. Application
Both VPS and VDS are a type of virtual server, and they have almost the same uses. Still, when it comes to capacity, stability, heavy projects, and traffic websites, you need a server with guaranteed capabilities so that if the traffic or other load The virtual versions on the dedicated server have problems, be sure to maintain the performance and stability of your server, and in this case VDS is a good option.
But in general, if you make the right choice and choose a VPS or VDS that suits your needs, both of these can get you there. Implementing websites and applications, setting up an email server, setting up a game server, trading, etc., are all among the primary users of the virtual server.
8. security
Security is also one of the critical factors in examining the difference between VPS and VDS.
Considering that the isolation level of VDS is higher than that of VPS and hardware resources are provided to the user in a fixed and guaranteed manner, the security of VDS is higher than that of VPS, but this does not mean that you are 100% protected from attacks. Stay safe, hacker.
There are many ways to increase server security, and you should think about implementing solutions and creating new firewall rules to prevent unauthorized access to your server. It is not smart at all to focus only on the isolation level and choose a secure VDS and not bother with security enhancement methods.
So, try to increase the security of VDS or VPS to the highest possible level by implementing solutions such as creating security settings, software updates, communicating with the virtual server support team, etc.
9. Customization
Both virtual servers provide users with sufficient access to make necessary changes and settings, such as installing software programs. However, VDS has more flexibility in this field, and its level of control is higher than VPS, which gives VDS users more possibilities and freedom in terms of technical management and server security.
10. Cost
In general, the average cost of VDS is higher than VPS, and after examining the nine differences between VPS and VDS, you are right.
The type of virtualization method, access to fixed and dedicated hardware resources, guaranteed performance, better stability (even in case of load or traffic more than neighboring VDS), and… are all reasons that make the cost of VDS higher. Especially since the stability of resources prevents the creation of many VDS versions on a server, this factor causes the limitation of its providers. in this way, the high cost of VDS seems more reasonable.
Of course, with all these features, you can achieve your desired performance and stability at a lower cost by purchasing a virtual server. Provided you know your needs and make the right choice based on them.
Are we considering the differences between VPS and VDS, which virtual server should we choose?
First, it is better to specify that both virtual servers can meet your expectations and provide you with a similar experience.
It is essential to know your needs and then decide on the hardware power of the server based on your needs and choose the right plan accordingly. Rest assured that if you purchase from a reputable provider, any concerns you may have about purchasing a VDS or VPS will be resolved. For example, most VPS providers try to divide resources between virtual servers so that excessive load or traffic of one version does not negatively affect the performance of other virtual versions of that server.
Generally
If budget is important to you and you want to own a powerful virtual server with high performance at an affordable cost, VPS is a better option.
If you need constant performance and stability and don’t want your high-traffic website to be disrupted by the activity of other virtual versions of the same physical server, VDS is a safer choice.
Suppose you are concerned about the security of your website, application or data. In that case, even though VDS offers a higher level of security, it is up to you to work with a reputable company and implement security measures and solutions to reach your desired level of security.
In terms of the level of control, both virtual servers can provide you with the necessary access, but if you need full control and want to manage settings and features more flexibly, VDS is a better option for you.
Conclusion
VDS and VPS are both good options for virtual server fans, each with its own advantages and disadvantages and can best meet the needs of your projects. However, VDS offers better performance, security, and control and is a better option for heavily trafficked sites. But if you know the hardware requirements of your website or application and want to get the server you need with a lower budget, you can achieve your goals by choosing a suitable VPS.
