When a VPS is enough." url: https://tihost.io/en/blog/vps-vs-vds-vs-dedicated language: en section: "Basics" published: 2026-09-24 updated: 2026-10-05 publisher: Tihost (https://tihost.io) --- # VPS vs VDS vs dedicated server: the difference and how to choose > **In short:** VPS and VDS mean the same thing today: a virtual server with its own OS and root access on a shared physical machine. Historically, VPS meant containers (OpenVZ) and VDS meant full virtualization, but almost everyone now uses KVM and the names became synonyms. A dedicated server is a whole physical machine: you need it when even a large VPS is not enough or the task requires special hardware. **Key takeaways:** - VPS (Virtual Private Server) and VDS (Virtual Dedicated Server) mean the same thing today - a virtual machine with its own OS and root access on a shared physical server, almost always using KVM virtualization. - Historically, VPS meant OpenVZ containers without their own kernel and VDS meant full Xen or KVM virtual machines; when choosing a virtual server, the virtualization type matters, not the name. - A dedicated server is a whole physical machine: it is needed when even the largest VPS is not enough, the task requires special hardware such as GPUs, or the rules forbid a shared physical machine. - A vCPU is a host CPU thread the hypervisor assigns to a virtual machine; the VPS operating system sees as many processors as the plan has vCPUs. - A Tihost VPS is deployed in about 2 minutes and costs $4.00 to $77.50 a month - from 1 vCPU and 2 GB of RAM up to 16 vCPU and 32 GB. ## Three kinds of hosting at a glance - **VPS** (Virtual Private Server) and **VDS** (Virtual Dedicated Server) - a virtual machine on a shared physical server. Your own OS, your own resources, root access. - **Dedicated server** - the entire physical machine is yours. - **Shared hosting** - space for a website on a server where you do not control the OS and share it with other customers (compared in detail in [shared hosting vs VPS](https://tihost.io/en/blog/shared-hosting-vs-vps)). ## Where the two names come from In the days of OpenVZ container virtualization, virtual servers shared the host's OS kernel: you could not install your own kernel, load a module or run Windows. Those servers were often called VPS. Full virtual machines (Xen, then KVM) with their own kernel were sold as VDS - a "virtual dedicated" server. Almost every host now uses KVM, and both terms mean the same thing. Look at the virtualization type, not the name. Tihost VPSes are [KVM](https://tihost.io/en/blog/vps-features) virtual machines: their own kernel, Docker, WireGuard, kernel modules, Windows Server. ## Comparison | | VPS / VDS | Dedicated server | Shared hosting | | --- | --- | --- | --- | | What you get | A virtual machine | A physical server | Space for a website | | Root access and own OS | Yes | Yes | No | | Isolation from neighbours | Hypervisor | Full | Shared OS | | Setup time | Minutes | Hours or days | Minutes | | Changing the configuration | Move to another plan | Hardware swap | Change plan | | Price | From $4.00 a month | Usually tens of dollars and up | The lowest | | Used for | Bots, websites, APIs, VPN, CI, databases | Large databases, special hardware | Simple websites | *VPS price - Tihost plans; dedicated and shared hosting prices depend on the provider.* ## What a vCPU is A vCPU is a host CPU thread the hypervisor assigns to your machine. The server OS sees as many processors as the plan has vCPUs. Performance depends on the host CPU: at Tihost it is the [AMD Ryzen 9 5950X and 9950X](https://tihost.io/en/blog/amd-ryzen-9-5950x-vs-9950x), with the high per-core clock that matters for bots, databases and websites. Server load is visible in the panel and in the bot. Other terms - hypervisor, NVMe, root - are explained in the [VPS glossary](https://tihost.io/en/blog/vps-glossary). ## When a VPS is enough - Telegram bots and scrapers - see [how to run a bot on a VPS](https://tihost.io/en/blog/telegram-bot-on-vps). - Websites, online stores, APIs and mobile app backends. - Your own VPN, proxy, or game servers for friends. - CI/CD, test environments, [Docker](https://tihost.io/en/blog/install-docker-ubuntu-debian) containers. - Mid-size databases - the largest Tihost configuration offers 16 vCPU and 32 GB of RAM. ## When you need a dedicated server - The task consistently outgrows the largest VPS configuration. - You need special hardware: GPUs, many disks, hundreds of gigabytes of RAM. - A regulator or client explicitly forbids a shared physical machine. Otherwise a VPS is simpler: it is deployed in about 2 minutes, billed monthly with no long contract, and OS reinstall, console and reboot are available from the panel and the Telegram bot. **Launch a server in 2 minutes.** AMD Ryzen 9, NVMe and DDoS protection in Germany, Finland and Poland.

Today VPS and VDS are the same thing: at most hosts both names mean a KVM virtual machine. VPS used to often mean OpenVZ containers without their own kernel. ### Which is better for a website - a VPS or shared hosting? Shared hosting is simpler for one small PHP website. A VPS is needed for your own stack, background processes, Docker, bots, or several projects on one server. ### Can I install Windows on a VPS? Windows can be installed on a VPS with KVM virtualization. At Tihost, Windows Server is available when ordering and when reinstalling the OS. ### What if a VPS is no longer enough? When a VPS is no longer enough, move to a larger configuration - Tihost plans cost $4.00 to $77.50 a month depending on resources. If even the largest one falls short, it is time to look at a dedicated server. ### What is a vCPU on a VPS? A vCPU is a host CPU thread the hypervisor assigns to a virtual machine. The VPS operating system sees as many processors as the plan has vCPUs, and the speed of each depends on the host CPU model. --- Updated 2026-10-05 ยท https://tihost.io/en/blog/vps-vs-vds-vs-dedicated
