12. What are the different cloud deployment models?

Cloud deployment models are a type of virtual computing environment that authorize you to decide how much data is to be shared and decide who gets access to the whole system.

There are usually four types of deployment models, i.e., – 


Public cloud: As the name suggests, it is accessible by the public and enables cloud services across the public internet and server. This model is excellent for organizations with growing and fluctuating demands and companies with low-security concerns. 

Private cloud: Here, the cloud computing services are offered either over the private internal network or the internet platform available to the selected users. A private cloud model is integrated with a company’s data center and managed by its IT team. It is beneficial for companies looking for cost efficiency and wanting more control over their data and resources.

Hybrid cloud:  It is a combination of two or more cloud architectures, and within this cloud system, the internal or external providers can offer resources.

Community Cloud: It is similar to the public cloud with only one difference, i.e., it allows access to a limited set of users who share similar goals and use cases.
