- 6. Cloud Deployment Models Private Cloud • Infrastructure is dedicated to a single organization and may be located on-premises or off- premises. • Private cloud environments are designed to meet specific security, compliance, or performance requirements. • They offer enhanced control, customization, and privacy but require significant upfront investment. Dr. Jay Sarraf, School of Computer Engineering, KIIT Deemed to be University Introduction Cloud Computing
- 7. Cloud Deployment Models Hybrid Cloud • Combines public and private cloud environments, allowing for flexibility and data sharing between the two. • Organizations can leverage the benefits of both public and private clouds, ensuring optimal resource allocation. • Hybrid cloud deployments enable workload portability and seamless integration between different environments. Dr. Jay Sarraf, School of Computer Engineering, KIIT Deemed to be University Introduction Cloud Computing
- 8. Cloud Deployment Models Community Cloud • Community cloud is a deployment model where infrastructure and services are shared among a specific community or group of organizations. • It caters to the needs of a particular community, such as government agencies, educational institutions, or research organizations. • Community cloud provides a cost- effective solution while addressing specific requirements and compliance standards of the community.

- 9. Service Models Infrastructure as a Service (IaaS) IaaS provides virtualized computing resources over the internet. Users have control over the operating systems, storage, and networking components. They can provision and manage virtual machines (VMs), storage, and networks according to their requirements. Examples of IaaS providers include AWS EC2, Azure Virtual Machines, and Google Compute Engine. Dr. Jay Sarraf, School of Computer Engineering, KIIT Deemed to be University Introduction Cloud Computing
- 10. Service Models Platform as a Service (PaaS) PaaS offers a platform for developing, testing, and deploying applications. Users can focus on application development without worrying about infrastructure management. PaaS providers manage the underlying infrastructure, including servers, storage, and networking. Developers can leverage pre-configured environments, development frameworks, and deployment tools. Examples of PaaS providers include Heroku, Google App Engine, and AWS Elastic Beanstalk. Dr. Jay Sarraf, School of Computer Engineering, KIIT Deemed to be University Introduction Cloud Computing
- 11. Service Models Software as a Service (SaaS) SaaS delivers software applications over the internet on a subscription basis. Users can access and use applications directly through a web browser or APIs. The provider hosts and manages the underlying infrastructure, application, and data. Users can typically customize certain aspects of the application to fit their needs. Examples of SaaS include Salesforce, Microsoft Office 365, and Google Workspace.
