There are different types of cloud computing and different opinions on how they should be categorized. Personally, I find four types most logical:
- Private: Everything hosted internally, in our own data center.
- Hosted: Something between a private and public cloud; the service provider creates a separate environment in their data center and offers us an isolated cloud for our use only.
- Public: The service provider offers a service available to everyone—publicly available. There is still tenant isolation but we'll talk about this later.
- Hybrid: A combination of private and public cloud. Some services are used in the public cloud but some stay in our local data center with direct connection between two or more environments. ...
