Dedicated vs VPS vs cloud vs bare metal is one of the first decisions you face when a site or app outgrows shared hosting. All four give you more control than shared hosting, but they differ in how the hardware is shared, how fast you can scale and how much work they need. This guide compares them honestly so you can choose.
Before you start
Write down what you actually run: number of sites or apps, monthly visitors, database size, peak CPU and RAM use, and whether anyone on your team is comfortable administering Linux. Those numbers matter more than labels.
The server types at a glance
| Type | Hardware | Root access | Scaling | Admin effort |
|---|---|---|---|---|
| Shared hosting | Shared with many accounts | No | Upgrade plan | Very low |
| VPS | Virtual slice of one host | Yes | Resize, usually with reboot | Medium |
| Cloud server | Virtual machine on a cluster | Yes | Fast resize, add nodes via API | Medium to high |
| Dedicated server | Whole physical machine | Yes | Hardware change or new server | High |
| Bare metal (cloud) | Whole physical machine, provisioned on demand | Yes | Order more machines via API | High |
VPS (virtual private server)
A hypervisor such as KVM splits one physical server into several virtual machines. Each VPS has its own operating system, guaranteed RAM, virtual CPU cores and disk, and you get root access.
- Good for: custom software stacks, Node.js or Python apps, small to medium sites, staging environments, VPNs.
- Watch for: CPU cores may be shared with other VPSs on the same host, so heavy neighbours can affect performance on oversold hosts.
Cloud servers
A cloud server is also a virtual machine, but it runs on a pool of hosts with network storage. If a host fails, the VM can restart on another one, and you can resize or clone it in minutes.
- Good for: traffic that changes a lot, apps built to scale horizontally, teams that automate with APIs.
- Watch for: network storage can be slower than local NVMe, and pay-as-you-go bandwidth can make bills unpredictable.
Dedicated servers
You rent a whole physical machine: every CPU core, all RAM and all disks are yours. There is no hypervisor overhead and no noisy neighbours.
- Good for: large databases, busy e-commerce, game servers, hosting businesses running WHM, workloads with steady high load.
- Watch for: hardware faults are handled by swapping parts, which takes longer than restarting a VM; upgrades often mean migrating.
Bare metal
"Bare metal" means a physical server with no virtualisation layer chosen for you. The term is often used for dedicated servers that a provider can deploy automatically in minutes, like a cloud VM but on real hardware. You can install your own hypervisor (Proxmox, VMware, KVM) and carve it into your own VMs.
How to choose
- Can shared or reseller hosting do it? For WordPress and PHP sites the answer is often yes, and the host handles security and updates. MdmHost web hosting and reseller hosting run cPanel with LiteSpeed and NVMe storage.
- Need root or custom software? Start with a VPS.
- Load changes a lot or you want automation? Choose cloud.
- Steady heavy load or strict isolation? Choose dedicated or bare metal.
- No Linux admin skills? Pick a managed option or stay on shared hosting.
FAQ: dedicated vs VPS vs cloud
Is a VPS faster than shared hosting?
Not automatically. A well-run shared server with LiteSpeed and caching can beat a small, untuned VPS. A VPS wins when you need guaranteed resources or software shared hosting cannot run.
Is bare metal the same as dedicated?
Mostly. Both are single-tenant physical machines; "bare metal" usually stresses fast, automated provisioning and no pre-installed hypervisor.
Can I move from a VPS to a dedicated server later?
Yes. With cPanel you can use the WHM Transfer Tool; for custom stacks you migrate files, databases and configuration yourself.
