Virtual hosting: what are VPS and VDS, how to choose the appropriate tariff
VPS (Virtual Private Server) and VDS (Virtual Dedicated Server) are classes of hosting services that provide virtual server resources with certain characteristics to users for rent.
Difference between VPS and VDS
Despite the difference in names, the concepts of VDS and VPS currently represent the same service: renting a virtual server.
In fact, there is a difference between these terms. It lies in the virtualization method.
Therefore, VDS should be used for hardware virtualization, and VPS when virtualization is used at the operating system level.
However, from a user’s point of view, there is no difference between these approaches, so both abbreviations are now equivalent and depend more on the positioning of the service by the operator than on any technical nuances.
When a company needs a virtual server
Today, a company’s business is almost impossible without IT. At least without a website. As long as we are talking about simple websites and landing pages, shared hosting is quite enough for a company. This is a service that includes support for multiple domain names, web development tools, databases and disk space.
As companies grow and implement CRM, the potential of shared hosting should not be overlooked. Typically, computing resources and database volumes are the first to run out. In practice, with shared hosting, the client will only need a small part of the processor (usually 3-5% of rated performance) and a small part of the disk space (20-30 GB, although this figure increases when upgrading to a more expensive plan). In practice, this leads to error 503 (the server is temporarily unable to process the request for technical reasons). When renting a VPS/VDS virtual server, the company receives more resources.
Dedicated virtual servers are mainly popular among small and medium-sized businesses. As a rule, they are used as a platform for individual company services (for example, accounting programs) and special projects, large online stores, high-load network services, software development and testing, and many other tasks.

Virtual server in Switzerland implies the allocation of a virtual server with maximum privileges. You have the opportunity to ensure increased security of information storage, a powerful and stable connection, wide access to all possible resources on the Internet, guaranteeing trouble-free operation of Internet resources, etc.
How a VPS/VDS server works
The hardware basis of VDS/VPS is a physical server with special software installed, the computing resources of which (processor, RAM, disk space) can be distributed among several users. At the same time, each virtual server operates independently of the others. For example, the failure of one of the virtual servers does not affect the operation of other systems located on the same hardware platform.
Unlike regular hosting, where several users usually share one IP address, in the case of VDS / VPS, each virtual server is assigned its own IP. In addition to the virtual resources themselves, VDS/VPS operators usually provide DDoS protection, data backup, and administration and configuration assistance for an additional fee.
Clients can manage the VDS/VPS allocated to them as their own remote physical server. For example, they can install operating systems and application software, and set access rights.
The resources of VDS/VPS servers can be increased as needed, but unlike IAAS services, it is not possible to create virtual networks and clusters within a single virtual infrastructure. VDS/VPS is actually an intermediate stage between classic hosting and renting physical (dedicated) servers at operator sites.
How to choose a suitable VPS/VDS tariff
The main resources of a VPS/VD are the number of VCPU cores, the amount of RAM, the amount of HDD disk space and the type of disk used (usually a choice between SATA, SAS and SSD). The cost of a virtual server also depends on the volume of selected resources.
Minimum configurations require one VCPU core, 0. 5 GB of RAM and 5 or 10 GB of disk space. The cost of such tariffs is within 100 pages per month.
The most powerful VPs include up to 24 VCPU cores, up to 160 GB of RAM and up to 8 TB of disk space. Such virtual servers cost more than 35, 000 per month.
The preferred operating system affects the VPS price. For example, VPS plans with a small amount of RAM do not offer a Microsoft operating system, as Windows has higher requirements than Linux. Additionally, VPS plans use the FreeBSD operating system from 1C-Bitrix. The most common virtualization platforms are KVM, Xen, Open-VZ, Hyper-V, and VServer.
For easy selection of VPS/VDS providers and their plans, service providers offer filters. The search for a suitable VPS is based on a database of multiple plans from various providers.
To select a plan, select the appropriate number of VCPU cores, RAM, and disk storage size and type. You can also select the operating system, virtualization platform, processor clock speed, and server deployment country. After clicking the ‘Pick’ button, the corresponding VPS/VDS plans will be displayed in the table, indicating the provider, plan features, and their prices. All plans are sorted by price by default.
