Three organisations, three choices
A local clinic holds private patient records. A student club needs somewhere to share photos. A university shares equipment with other universities.
All three want the cloud, but the best kind is different for each. Today you learn the types and how to match one to a need.

Note
I can recommend a cloud type for an organisation and explain the security points to check.

Four types, by who shares the cloud
The type of cloud says who shares it. Public cloud is shared by many customers and is cheap to start. Private cloud is for one organisation, which gives more control and costs more.
Hybrid cloud joins both, so private data stays in the private part. Community cloud is shared by a few organisations with similar needs, such as several hospitals.
The four types side by side
| Type | Who uses it | Control | Cost | A good fit |
|---|---|---|---|---|
| Public | Many customers | Less | Low to start | A student club sharing photos |
| Private | One organisation | Most | Higher | A clinic with private records |
| Hybrid | One organisation using both | Mixed | Medium | A shop with private orders and a public web shop |
| Community | A group with shared needs | Shared | Shared | Universities sharing research tools |

A common mistake
Warning
Many people think private cloud is automatically safe and public cloud is not. Safety depends on how well it is set up and managed. A well-run public cloud can be safer than a badly kept private one.
