2. Definition and Key Concepts Cloud computing refers to the delivery of computing services over the internet, offering access to shared resources, such as storage, processing power, and applications. Key concepts include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service.

3. Benefits of Cloud Computing Cost-Effective Cloud computing reduces the need for extensive hardware and ongoing maintenance costs, resulting in significant savings for businesses. Scalability Organizations can easily scale their resources up or down based on demand, avoiding unnecessary over-provisioning of infrastructure. Flexibility Cloud services offer the flexibility to access data and applications from anywhere with an internet connection, enabling remote work and collaboration. Disaster Recovery Cloud-based backup and recovery solutions provide added protection and quick restoration of data in the event of a system failure or disaster.

4. Types of Cloud Computing services Infrastructure as a Service (IaaS) With IaaS, users can rent IT infrastructure like virtual machines, storage, and networking. It provides the flexibility to scale resources up or down according to demand. Platform as a Service (PaaS) PaaS offers a platform allowing customers to develop, run, and manage applications. It eliminates the need to manage the underlying infrastructure. Software as a Service (SaaS) SaaS delivers software applications over the internet on a subscription basis. Users can access the software from any device with an internet connection.

5. Infrastructure as a Service (IaaS) Virtual Servers Access virtual servers to run applications and store data remotely. Network Infrastructure Utilize cloud-based network infrastructure for connectivity and communication. Scalability Scale resources up or down based on demand and business needs.

6. Platform as a Service (PaaS) Scalability: PaaS allows for easy scalability, enabling businesses to adjust resources as needed without over-provisioning. Development Tools: It provides a range of development tools to facilitate application development, testing, and deployment. Cost-Effective: PaaS reduces infrastructure costs and streamlines development efforts, leading to cost savings for organizations.

7. Software as a Service (SaaS) Accessible Anywhere: SaaS applications are accessible from any internet-enabled device. Automatic Updates: Regular updates and maintenance are managed by the SaaS provider. Scalability: Easily scalable to accommodate the changing needs of the organization.

8. Cloud Computing deployment models 1 Public Cloud Services provided over a public network 2 Private Cloud Operated solely for a single organization 3 Hybrid Cloud Combines private and public cloud services

9. Public Cloud Scalability and Flexibility Public cloud services offer scalable resources and flexible infrastructure to accommodate varying workloads and demands. Cost-Effective Solutions Organizations benefit from cost-effective solutions, avoiding the need for upfront investments in hardware and maintenance. Robust Security Measures Public cloud providers implement advanced security measures to protect data and ensure compliance with industry standards.

10. Private Cloud Control Offers greater control and customization over infrastructure and resources. Security Enhanced security features and data protection, especially for sensitive information. Cost Potential cost savings through resource optimization and efficient management. Flexibility Flexibility to tailor services to specific business needs and requirements.
