VPS/VDS vs Dedicated Server

What is a VPS/VDS?

VPS or Virtual Private Server (also known as Virtual Dedicated Server) hosting is a type of hosting that falls between shared hosting and dedicated hosting. While you use a portion of a physical server’s resources, the amount allocated to you is fixed.

Imagine your virtual server is deployed on a physical server with 8GB RAM. If your service plan promises you 1GB RAM, you will get exactly that much RAM. Your “neighbors” cannot use your allocated resources.

To make this possible, hosting providers use special software called hypervisors. With the help of hypervisors, virtual machines with specified resources are created for each customer on the server. This virtual machine acts like a separate server where you can install your operating system and other necessary software like a control panel or LAMP/LEMP stack. Due to virtualization, VPS/VDS can be set up very quickly.

Moreover, the user does not need to be a highly skilled administrator. Although VPS/VDS requires minimal administration skills, most actions like OS and application installation are automated. And if you still need to do more fine-tuning, you can use root access, which most providers offer.

Scaling a virtual server is also easy. If you feel that your project is reaching the limit of its current resources, you can request an upgrade while continuing to use the same virtual machine

What is a DC (Dedicated Server)?

A dedicated server is the most flexible, powerful, and reliable way to host a website. As the name suggests, you have an entire physical server with a full set of resources available to you. Here, you don’t need to share space with other clients, which makes a dedicated server significantly different from shared hosting and VPS/VDS.

Detailed Comparison – (VPS/VDS vs Dedicated Server)

Criteria VPS/VDS DS (Dedicated Server)
Resource availability Dedicated resources, part of the physical server’s resources 100% of the resources of the physical server
Security “Neighbors” on the physical server, but their data does not affect your server’s operation No “neighbors,” physical server fully at your disposal
Performance High, except in cases of high load on neighboring VDS Always high
Configuration and setup Software customization freedom (software tools and OS) Full customization: software, OS, and hardware
Scalability Easy and almost instant virtual resource reallocation Needs costly physical parts upgrades
Cost Moderate High

Comparing Resource Allocation: VPS/VDS vs Dedicated Servers

VPS/VDS: A virtual server (VPS/VDS) uses a portion of the physical server’s resources to run a virtual machine. These resources are entirely at your disposal, and your server’s “neighbors” cannot use them.

Dedicated Server: A dedicated server (DS) uses 100% of the resources because it is a fully physical machine. This means you don’t have to worry about other users, giving you complete control over the server’s resources.

If your project always requires high, unaffected performance, choose a dedicated server as it provides the full power of the server.

Which Is More Secure: VPS/VDS or Dedicated Servers?

VPS/VDS: A virtual server (VPS/VDS) is a quite secure solution. You can install any software for protection, but the presence of “neighbors” on the physical server can make it more vulnerable. If another user’s account on your physical server gets hacked, your VPS/VDS can also be compromised.

Dedicated Server: A dedicated server (DS) is a physically isolated environment. There are no other users, allowing you to install necessary software, configure protection, and have complete control over mitigating incidents.

A dedicated server is a more secure option. While VPS/VDS provides a high level of security, a dedicated server gives you full control over the security system.

Performance Comparison: VPS/VDS vs Dedicated Servers

VPS/VDS: A virtual server (VPS/VDS) is a balanced sweet spot among website hosting options. Although the overall load speed and performance of a site on a VPS/VDS are lower than a dedicated server, it is sufficient for small commercial or large private sites that demand more resources than virtual hosting. This type of hosting speeds up hosted sites’ loading and avoids downtime. It also handles sudden traffic surges well.

Dedicated Server: A dedicated server (DS) is the most powerful website hosting option available. These servers typically use the most advanced hardware and provide the highest bandwidth. This helps withstand sudden bursts of traffic and maintain high load speed at all times.

Due to its raw power, a dedicated server provides high speed and performance for hosted websites. In this regard, VPS/VDS isn’t far behind, but if there’s a traffic surge on some sites, it can slow down.

Customization and Configuration: VPS/VDS or Dedicated Servers?

VPS/VDS:  Starting with a virtual server (VPS/VDS) does not require high server administration skills. Since it is only a part of a physical server, the provider creates a virtual machine and sends you the necessary access data so you can start working on your VPS/VDS. Additionally, you can customize the server using automatic tools or root access, allowing you to modify the VPS/VDS on the fly.

Dedicated Server: A dedicated server (DS) also provides automatic configuration tools and root access. However, in this case, managing the physical server is the customer’s responsibility. Therefore, a dedicated administrator might be required to manage the server. Alternatively, some providers offer remote administration services.

A virtual server is easier to manage and more flexible in customization, while a dedicated server requires deep administration skills but allows for hardware changes.

VPS/VDS vs Dedicated Servers: Scalability Comparison

VPS/VDS: A virtual server (VPS/VDS) is a highly flexible solution. With virtualization, you can easily change the resource limits of a particular VPS/VDS. For instance, if the number of regular website visitors increases and the allocated resources are not enough for stable performance, you can upgrade your service plan without worrying about migrating the site to another server.

Dedicated Server: A dedicated server (DS) is a more static solution. With more resources and high performance, a physical server hits a concrete ceiling in terms of its hardware. To change the configuration, you need to replace hardware in the data center or move to a new server.

In terms of scalability, a virtual server is better than a dedicated server. With flexible service plans and the ability to quickly change them, you can easily adjust to the growing needs of a website. A dedicated server immediately provides many resources, but upgrading is quite difficult.

VPS/VDS vs Dedicated Server Pricing Comparison

VPS/VDS: A virtual server (VPS/VDS) is a midrange hosting option. The cost of renting a physical server is split among all “neighbors,” making it a great value for money. It is a full-fledged server that can be fine-tuned at a lower cost than a dedicated server.

Dedicated Server: A dedicated server (DS) is the most expensive option for website hosting. High performance, speed, and reliability are achieved using expensive modern hardware. Additionally, in this case, you rent the entire machine, so the total amount is not shared with anyone.

A virtual server provides better value for money for medium-scale projects. If you have a site with a large flow of users and need to ensure its smooth operation, a more expensive dedicated server will be the right fit.
