With the increasing influence of the Internet, every day more and more users go shopping online and request services of any kind entirely online. In order for these businesses to operate, they need powerful servers with predictable performance. For many years, we used to see that the solution was a bare metal server, but these things change.
We, at VPSBG.eu, believe that the Virtual Dedicated Servers is a better option when dedicated resources are needed. Before, if you have to have dedicated resources for your let’s say big e-commerce website, you rent a bare metal server or you buy the server yourself and collocate it in a data center. This, as you might guess, is not scalable, it is harder to maintain, manage and it is expensive. The VDS servers are a solution to these issues.
Why Virtual Dedicated Server (VDS)?
Subsequently, hypervisor technologies made it possible to have multiple virtual machines running on the same hardware. Completely separated virtual servers, every one of them has its own resources like CPU, RAM, Disk storage, etc. That’s how the service Virtual Private Server (VPS) appeared. The difference between VPS and VDS is that one or more resources are shared between the virtual machines. When using the VDS service, you receive a virtual server with guaranteed resources. You have 100% of the CPU which you can spin up to 100% round-the-clock. The RAM and other resources are also reserved for you. It is like a dedicated server, but virtual. And better. This is how the abbreviation VDS (Virtual Dedicated Server) appeared.
And it is better because with these new generation servers, you have the flexibility to upgrade your resources any time and instantly: increase or decrease the number of the AMD EPYC CPU cores, increase or decrease the size of RAM, increase or decrease the disk storage capacity. This could be done the hard way when we talk about a physical server. First, you have to buy the parts, then install them and this results in a bigger downtime, compared to VDS. The downgrade is even harder.
What is it useful and suitable for?
A virtual dedicated server is ideal for sites that exceed the capabilities of conventional hosting, high-load network services, as well as for the design, development, and testing of software. Closed corporate projects with increased requirements for security and data confidentiality for the most part are also based on virtual dedicated servers, especially for small companies for which the purchase or lease of a physical server is not accessible.
If you have a small website, you do not have to host it on a VDS server. For example, you can use a less expensive option (e.g. shared hosting). However, keep in mind that in this case, you will only be able to use the software installed by your provider. And the performance of your site will fully depend on the load of the shared hosting neighbors. It might get too noisy.
How reliable is it?
As we said earlier, the VDS server has dedicated resources. This makes them powerful because the performance is predictable and guaranteed. Your plan gives you 4 CPU cores, and you receive 4 physical CPU cores. Entirely for you. If your application is CPU intensive, this service gives you credibility that it will work 100% of the time.
A separate server gives you full control over the system, from managing user accounts and installing software to configuring network interfaces and firewall rules. In order to perform these actions, however, you must possess a specific level of qualification as a system administrator. It is valid for both virtual and hardware servers.
How versatile is it?
Nowadays, you can get services of various types and models (SaaS, PaaS, IaaS, etc.). The dedicated virtual server is part of the IaaS (Infrastructure-as-a-Service model), the most versatile cloud service consumption model. Based on a virtual machine, you can build any information system you need, install any operating system and software, configure any network. You can upgrade/downgrade it anytime with just a few clicks.
To wrap it up!
Now that you have read about VDS and its features, you can decide whether your business or you personally need one. To summarize, as you already understood, this service is like a virtual private server but with guaranteed resources. And because of the benefits of the KVM virtualization, it acts like a real dedicated server.
One of the most important differences between the two is that the VDS, unlike a bare metal server, allows a quick upgrade or downgrade of the computing power. Virtual Dedicated Server makes it easier and flexible to host and manage your application as long as you possess the necessary skills in system administration.
