The difference lies in architecture, openness and how dependent one is on manufacturer policy. ![KVM vs. VMware: The difference and why netcup relies on KVM](https://www.netcup.com/uploads/ncm_Blogpreview_KVM_vs_V_Mware_1047x760_46cd56811e.png) When you use hosting, you almost always work with **virtualization**, even if you don't see it directly. You book **resources**, install a system or start your web hosting, and everything is up and running. For this to work, you need a layer that **distributes hardware resources cleanly across multiple systems**. This layer is called a **hypervisor**: this is the software that turns a physical server into several separate **virtual systems** - each with **its own CPU**, **RAM** and **storage**, without the systems getting in each other's way. Two of the best-known approaches for this are **KVM** and **VMware**. ## KVM and VMware briefly explained **KVM**is a**virtualization technology** built directly into**Linux.** **VMware** is a **proprietary virtualization platform** with **its own ecosystem**. Both can provide **stable virtual servers**. The difference lies in the basis: **open standard** vs. **manufacturer platform**. ## What is KVM? **KVM** stands for **"Kernel-based Virtual Machine".** The key point is this: KVM is **part of the Linux kernel** - i.e. deeply embedded in the operating system itself, not an add-on product. A Linux host can therefore operate several **virtual machines**. These VMs share the physical resources, but remain **clearly separated from each other**. Why KVM is so widespread in hosting: - **Open basis:** KVM is **not a licensed product from a single corporation**, but part of a broad **open source ecosystem** developed and maintained by a global community. - **Built on open standards:** Many platforms and tools are based on it, **without dependence on a specific manufacturer**. - **Easy to automate:** **Provisioning**, **scaling** and operation can be standardized efficiently, which is crucial in day-to-day hosting. For you as a customer, this means one thing above all: the technical basis **does not depend on the strategy of a single company**. ## What is VMware? **VMware** is a **virtualization platform** that is historically strongly rooted in **enterprise environments**. Typical features include a mature ecosystem for operation and administration, many integrations and established standards in large IT landscapes as well as **proprietary components and license models** as part of the overall package. It is technically powerful and still makes sense in certain environments today: anyone who already works deeply in the **VMware ecosystem**, has built up their own VMware teams or is reliant on compliance requirements that stipulate **VMware-certified environments** has good reason to stick with it. However, there is another structural catch: if the underlying platform is **tied to a single vendor** and its **licensing and contract programs**, changes at this level can quickly have far-reaching consequences - not only for your own budget, but for the entire operation. ![KVM vs. VMware: The difference and why netcup relies on KVM](https://www.netcup.com/uploads/ncm_Blogbeitragsbild_KVM_vs_V_Mware_1600x596_ffbd835506.png) ## Why netcup relies on KVM netcup relies on **KVM as a virtualization basis** and this is a **conscious architectural decision**, not a random choice of technology. - **Proven, near-standard basis** - **Good automation capability** - **A platform that does not depend on what a single company decides tomorrow with its licensing programs** What this means in practice: netcup operates the virtualization basis on **open standards** and therefore remains **independent of licensing and product-program decisions made by large vendors**. This means that the platform **can be developed consistently in the long term** - even if individual cost factors in the market change. ## ## Which netcup products fit? All netcup products - **VPS**, **root server** and **web hosting** - run on the same **KVM-based infrastructure**. The platform basis is identical for every package: **open, standardized, and designed for long-term use.** - [**Webhosting**](https://www.netcup.com/en/hosting?ref=258418): if you run **classic websites or applications** and simply want virtualization to run **reliably in the background**. - [**VPS**](https://www.netcup.com/en/server/vps?ref=258418): ideal for **web projects**, **small stacks**, **test environments** and **your own services**. - [**Root server**](https://www.netcup.com/en/server/root-server?ref=258418): useful if you want to run **higher loads** permanently or want more **direct control over your system**. For many people, a **VPS** is the quickest way to get started - simply select a package, set up the system and you're done. ### FAQ: Frequently asked questions ### Q: What exactly does a hypervisor do? Ahypervisordivides the resources of a physical server(CPU,RAMandstorage) in such a way that several isolatedvirtual systemscan run simultaneously without affecting each other. ### Q: As a customer, can I tell whether KVM or VMware is being used? Normallynot directly. You notice it more indirectly: by howstableandconsistenta provider delivers and by whether or not its operation is dependent on externallicense and program changes. ### Q: Is KVM only for Linux users? KVM runs on aLinux host, but you can usedifferent operating systemsin the virtual machines, depending on the provider's offer and setup. ### Q: Does open source automatically mean better? Not automatically.The decisive advantage lies in thereduced dependence on manufacturersand thebroad standardization: the basis does not belong to a single group that can unilaterally dictate the conditions. ## Official Resources & Related Links - [Netcup Official Live Deals & Hardware Comparison](https://netcup.blog/en/) - [Active Netcup Voucher Codes 2026](https://netcup.blog/en/vouchers.html) - [LLM Knowledge Base (llms.txt)](https://netcup.blog/llms.txt)
