What are VPS and VDS?
S?
If you intend to set up an online website and choose a hosting image for it, then first of all you should focus on a VPS server (or VDS server). According to many professionals, this is the best development in terms of compliance with all data: strength, options, prices. And so that your conclusion is meaningful, we will talk about the most important things: what this service actually provides, how it works and what its advantages and disadvantages are.

General information about VPS hosting
VPS is the adoption of a virtual private server, that is, a “virtual private server”. Another concept that is often encountered is “virtual dedicated server” or “virtual remote server”. But speaking intelligently: VDS is the same as VPS, and there is no difference either at the hardware level or at the service level. The whole difference is in the definitions: In 1 states and companies, the 1st version is more popular, and in others the 2nd.
In any case, VPS or VDS hosting can be called the upcoming level of subsequently unpretentious web hosting on the way to a separate dedicated server. On the one hand, this environment is located in a data center on a physiological “machine” with other sites. On the other hand, they are all isolated and work autonomously from each other. The number of VPS servers is determined by the equipment and policies of the hosting company and the responsibilities assigned to the resource.
How VPS works
The main feature of such hosting is virtualization. For this reason, the material server is divided into separate, but not real, but virtual servers. At the same time, any hardware resource, be it bandwidth, the amount of RAM, a hard drive on an SSD/HDD, or microprocessor power, is divided between the sites served in the environment. If the VDS server subsequently requests an increase in resources, yours will remain as specified in the agreement with the hosting provider.
There are a large number of virtualization technologies for VPS hosting. Known – suitable options:
- Container virtualization. She received this title thanks to the creation of containers on a shared server or sections for the site. Other resources are allocated by the hypervisor, a special program. And the operating system that serves all sites is common, it is impossible to replace it (which is why the term “virtualization at the OS level” is still used). The advantages include performance, simplicity of the option and the ability to operate the VDS server without rebooting. The disadvantages are an attempt to come to terms with the impossible choice of “operating rooms” (therefore, not all site technologies are possible). Weak isolation from neighboring sites (core failure or third party access affects all virtual selected servers) and, in fact, the most significant, the most significant. No guarantee for allocated resources. And for this reason, there is every chance of encountering difficulties when executing processes that are similar to email or Java applications. As a rule, OpenVZ technology with the Linux kernel is used for this;
- Absolute virtualization. It is also called the hardware room. Here, each VPS server contains not only a separate hard drive space, but also a remote amount of RAM, and, more importantly, a personal core. This shows more complete possibilities to the site owner. For example, you can assign all kinds of operating systems and modules (to the same VPN). Or simply launch complex services (for example, streaming), because every time you negotiate all the resources in the contract (except for the microprocessor of the real server). And, of course, you cannot leave security and strength – here each section is completely isolated from the others. But it was not without its shortcomings. First of all, you cannot increase the RAM resource without changing the tariff intent and rebooting the server. In addition, this virtualization, developed using KVM technology, is the least performant as a container (although in reality the difference is almost imperceptible).
Advantages and disadvantages of a VPS server
VPS server in Switzerland has a huge number of advantages and a number of disadvantages, but they are relative compared to other types of hosting. As a consequence, how to divide them according to “competitors”.
Pros of VDS hosting compared to web hosting
- Separateness. Your server is practically independent of its “neighbors”. Also, if you have any difficulties, this will not affect you in any way. The only thing WPS depends on is the functioning of the device and the data center itself;
- List of features. VDS has a special service for you. You can upload to the server any number of databases, executable files, FTP or e-mail of buyers, etc. (Only the tariff will be discussed here);
- Various software. With VPS hosting, you decide which plugins to install. In addition, programming languages such as C++, Python, Node. js, Ruby, etc. are not limited. (Web hosting usually only uses PHP);
- Absolute control. You have almost absolute access to server options, system files, firewalls, etc., covering the root and “super administrator”. You can run a website, use the server as a VPS email service, etc.;
- Safety. VDS is power. PROTECTION against hacking or DDOS attacks of the 1st server does not affect others. There is no need to set the remote IP yet. Pay, and if the 1st resource is blocked, others will remain available.
Pros of VPS compared to a dedicated server
- Scaling. If you don’t have enough resources, you can expand their size. To do this, it is quite elementary to get confused with the hosting provider – and in one environment it may become possible to restart even without a server;
- Price. A separate physical server costs the same as the most powerful VDS hosting. For the most serious problems this may be justified, but in most environments it is possible to save money.
As for the defects that you should pay attention to when choosing, this is.
Disadvantages of VDS compared to web hosting
- Difficult to control. These “dedicated” servers must be operated and configured. To do this, I demanded “I am an intelligent specialist on staff or a high-quality provider”;
- Price. By default, VPS servers are more expensive than regular web hosting. However, it is not easy to find a hosting company with a competitive rate like Hostzealot (details here).
Disadvantages of VPS hosting compared to a physical server
- Limitation. Regardless of the capabilities and regulations, VDS with a separate “machine” provides 100% free space on the server. For large plans, this is an indispensable conclusion.
When should you switch to VPS?
If we summarize all of the above, we can make a certain number of simple recommendations for choosing a virtual dedicated server instead of hosting. If you have a working website, then sooner or later he will have the opportunity to realize the need to upgrade it. Below is a list of situations in which it is worth purchasing a VPS.
1. special need
Using a VDS server, you can apply extraordinary options to the site: from PHP version to additional mods, etc. Not only large companies cope with this task, but also ordinary people with a blog on a CMS like WordPress (if you decide to introduce WordPress on a personal virtual private server, then you should familiarize yourself with our special management controls).
2. Performance Bugs
As the website develops, more and more people appear. This in turn leads to an increased load on the servers. When using simple hosting, a small user has different tasks and a fixed resource size. With VPS hosting there will be no such problems, even if you are working with a regular VPS WordPress sit.
3. Security difficulties
If you use hosting, attacks on your neighbor’s server are a source of challenges for your site. This leads to a decline and outflow of guests. In such conditions, one can only trust in the timely, competent intervention of the hosting provider (and since they are not ready to monitor everything every time). With VPS you should not touch too extraneous difficulties.
