Types of Cloud Computing

Public Cloud:

• Description: A service hosted by third party entities through the contra-internet, and hence accessible to anybody who would wish to utilize or acquire it.
• Examples: AWS, Microsoft Azure, Google Cloud Platform (GCP), Orchestrate, OpenShift, Kubernetes, Cloud Foundry.

Private Cloud:

• Description: An environment located on cloud that is less accessible and possibly dedicated to one organization to have full control on resources and security of that environment. It can be a physical server at a company’s location or it can be hosted in a server located in an internet hosting service provider location.
• Examples: vSphere by VMware, Open Stack, IBM get our Private Cloud.

Hybrid Cloud:

• Description: Hybrid of public and private cloud where data as well as applications are transferred from one cloud to the other. It results in flexibility, better resource utilization, security, and sound compliance of the existing arrangements.
• Examples: Such as AWS Outposts, Microsoft Azure Stack, and Google Anthos.

Community Cloud:

• Description: A multi-tenancy environment where several entities that have something in common, be it business or regulatory, host their solutions. It can be handled within the company or outsourcing the services to other companies.
• Examples: Cloud services for the government or healthcare institutions solving the requirement of the HIPAA or GDPR.

• Infrastructure as a Service (IaaS):

  Examples:

  • Amazon Web Services (AWS): Delivers computing resources with the use of networking technology-The internet.
  • Microsoft Azure: Provides a lot of cloud services among them include computing, analytical, storage and networking services.

  Platform as a Service (PaaS):

  Examples:

The concepts which may be incorporated in this model are flexibility, scalability and cost control. Key components of DaaS include:Key components of DaaS include:

• Cloud-Based Development Environments: Physical environments that form part of the program that can be opened and controlled from other areas.
• Collaboration Tools: Communication and cooperation platforms and tools that help with coordination and organizing of a team and its projects.
• Version Control Systems: Something as simple as Git that aids in tracking changes of the code base or different versions.
• Continuous Integration and Continuous Deployment (CI/CD): Automated procedure capable of compiling code alterations and the deployment of applications.
