Cloud Deployment models
Hybrid model :
-
Public cloud
-
-
Public cloud is suited for less confidential informations & Private cloud is more suited for confidential infos
Hybrid cloud comes as a popular model to address the disadvantages of both, the private and public models, and to benefit from the advantages of each one.
-
Public clous handles elastic ans cost-effective infrastructure and non-critical applications where no sensitive data are involved.

Summary
Hybrid cloud solutions combine public cloud hosting from a provider—like AWS, Microsoft Azure, or GCP—with an internal private cloud. These public and private clouds each have their own separate data centers, housed in different geographic locations. The two interact via a robust encrypted connection that enables applications, data, and other information to move between each system.
Private Cloud
Description
The private cloud refers to any cloud solution dedicated for use by a single organization. In the private cloud, you’re not sharing cloud computing resources with any other organization.
When to use ?
-
Companies that require strong control and security over their IT workloads and the underlying infrastructure
Large enterprises that require advanced data center technologies to operate efficiently and cost-effectively
-
-
Public Cloud
-
-
Predictable computing needs, such as communication services for a specific number of users
-
The public cloud refers to the cloud computing model in which IT services are delivered via the internet
Cost agility. The cost agility allows organizations to follow lean growth strategies and focus their investments on innovation projects
-
-
Business focus. The reduced complexity and requirements on in-house IT expertise is minimized, as the cloud vendor is responsible for infrastructure managemen
-
Community cloud
Benefits
-
-
Community cloud provides an infrastructure to share cloud resources and capabilities among several organizations.
-
The community cloud is comparatively more secure than the public cloud but less secured than the private cloud.
-
Since all data is located at one place, one must be careful in storing data in community cloud because it might be accessible to others.
It is also challenging to allocate responsibilities of governance, security and cost among organizations.
Description
Community Cloud allows system and services to be accessible by group of organizations. It shares the infrastructure between several organizations from a specific community. It may be managed internally by organizations or by the third-party. The Community Cloud Model is shown in the diagram below
