The types of cloud can be broken down into the following four broad categories:
1. Public Cloud
In this model, a third party provides resources such as storage, compute or network etc. to a large number of enterprises. The public cloud is based on the principle of shared or pooled resources.
2. Private Cloud
In the case of private cloud, the deploying entity sets up an exclusive data center on premise, which then delivers the above resources. In some cases, a private cloud may also involve colocation to curtail the exorbitant hardware costs.
3. Hybrid Cloud
A hybrid cloud is a combination of on premise and third-party data centers. In hybrid cloud, workloads are systematically allocated to both the clouds based on certain considerations that revolve around cost, efficiency and regulatory compliance.
4. Multi Cloud
The possibilities in case of multi cloud are limitless. This is a combination of both public and private cloud or the integration of multiple public cloud providers. This cloud model is difficult to integrate and manage, but also pays handsome dividends.
