Implementing Different Cloud Deployment Models
We will first look at the different cloud models and their characteristics. The most common cloud model is the public cloud, so let's start with that:
- Public Cloud: This is the most common model, where the CSP provides cloud services multiple tenants. This is like being one of many people who rent an apartment in an apartment block. Just like in the public cloud, none of the tenants owns their apartment:

Example: A small company does not want to invest $50,000 in IT systems, so they purchase their cloud package from a cloud provider where they and other companies are hosted by the cloud provider. This is similar to someone renting one apartment in a block from a landlord – you lease but do not own the apartment. This is a multitenant environment where the cloud provider has multiple companies on the same virtual host.
