Shared
Cheapest, simplest, no admin. Your performance depends partly on the neighbours. Right for most small sites.

Shared, VPS and cloud are not three grades of the same product. They are three different architectures with different failure behaviour, different cost curves and different assumptions about who is doing the system administration. Knowing which assumption you can live with is most of the decision.
The short answer
VPS
Guaranteed resources and root access on one physical machine. You own the operating system unless you buy managed.
Cloud
Resources pooled across a cluster, so hardware failure and traffic spikes are absorbed. Costs more, scales without migration.
Shared hosting: one server, many tenants
Shared hosting means your website is placed on a server that also hosts other websites. All users share the server's resources, such as storage and bandwidth. The provider runs one machine, divides it among many accounts, and enforces per-account limits so that no single customer can consume everything.
It is popular because it is affordable, easy to use, and provides enough performance for small websites without any technical server management. The trade-off is variability: on a badly managed platform, a neighbour's traffic spike becomes your slow afternoon. On a well-managed one, isolation technology makes that largely a non-event — which is exactly why the host's competence matters more than the plan's specification sheet.
VPS: one server, guaranteed slices
A virtual private server divides a physical machine into isolated virtual machines using a hypervisor. Each VPS has its own operating system and a reserved allocation of CPU, memory and disk. Your 4 GB of RAM is yours whether the other tenants are idle or hammering their instances.
That guarantee comes with an obligation. On an unmanaged VPS the operating system, web server, database, firewall and patching are all yours. This is completely reasonable if you have the skills and will keep spending the time. It is a liability if the person who set it up leaves and nobody logs in again for eight months. Managed VPS plans exist precisely for this reason and are usually worth the premium for a business without a sysadmin.
Cloud: many servers, pooled resources
Cloud hosting uses multiple connected servers, allowing your site to draw resources from a cluster rather than a single machine. Storage is replicated across nodes, compute can be restarted elsewhere if hardware fails, and capacity can often be added with a slider instead of a migration.
Cloud hosting generally offers better uptime, more scalability and improved stability under traffic spikes. It is not automatically faster — a single well-tuned server frequently beats a poorly configured cluster — and the billing model is more complex, with compute, storage and egress often charged separately.
Side-by-side comparison
| Shared | VPS | Cloud | |
|---|---|---|---|
| Resource guarantee | Best effort, capped | Reserved | Reserved, expandable |
| Isolation | Account level | Virtual machine | Virtual machine |
| Root access | No | Yes | Usually yes |
| Scaling | Change plan | Resize, brief reboot | Slider or automatic |
| Hardware failure | Down until restored | Down until restored | Restarts elsewhere |
| Admin burden | None | High (or pay for managed) | Low to medium |
| Typical cost | $3 – $15/mo | $20 – $150/mo | $18 – $300+/mo |
| Billing shape | Flat | Flat | Base + usage |
| Best for | Small sites | Custom stacks, apps | Growth, uptime, spikes |
How each one fails
This is the most useful lens, because every platform works fine on a good day.
- Shared degrades. You hit a CPU or process ceiling, requests queue, and visitors see slow pages or a 508 error. Recovery is usually automatic once load drops.
- VPS stops. You run out of memory, the OOM killer takes your database, and the site is down until someone logs in — or until a monitor restarts the service.
- Cloud usually moves. A failed node is replaced and your workload restarts elsewhere. A failed zone, however, takes everything in it, which is why multi-zone is a separate (and separately priced) decision.
Match the failure mode to your tolerance. A restaurant site that is slow for twenty minutes has lost very little. A booking platform that is down for twenty minutes has lost bookings and trust.
What each really costs
Add the invisible line: administration time. A $25 unmanaged VPS that needs three hours a month of skilled attention costs far more than a $60 managed plan. A $6 shared plan that forces an emergency migration during your busiest week costs more than either.
| Scenario | Hosting | Admin time | Realistic total |
|---|---|---|---|
| Shared, small business site | ~$430 | ~2 hrs/yr | Low |
| Managed WordPress, growing site | ~$900 | ~1 hr/yr | Low |
| Unmanaged VPS, self-administered | ~$900 | ~36 hrs/yr | High |
| Managed VPS | ~$2,340 | ~4 hrs/yr | Medium |
| Cloud, moderate traffic | ~$1,800 + egress | ~8 hrs/yr | Medium |
Choosing, in four questions
- What does an hour of downtime cost? If the answer is meaningful money, start at cloud and work down. If it is “not much”, start at shared.
- Who patches the operating system? If the honest answer is “nobody”, an unmanaged VPS is off the table.
- Do you need software the host will not install? If yes, you need root: VPS or cloud.
- How spiky is your traffic? Flat traffic suits a fixed server. Campaign or seasonal peaks suit a cluster that can absorb them.
