- 1. Cloud Computing: Concepts, Models & Future • Understanding the Technology Behind the Modern Digital Era • Your Name | Date
- 2. Introduction • Delivering computing services (servers, storage, databases, networking, software) over the internet. • Eliminates need for owning physical infrastructure. • Examples: AWS, Microsoft Azure, Google Cloud.
- 3. Evolution of Cloud Computing • 1960s: Concept of time-sharing & virtual machines. • 1999: Salesforce pioneered delivering apps via the internet. • 2006: AWS launched EC2 & S3. • Present: AI, big data, and edge computing integration.
- 4. Characteristics • On-demand self-service. • Broad network access. • Resource pooling. • Rapid elasticity. • Measured service.
- 5. Cloud Deployment Models • Public Cloud: Shared infrastructure, pay-as-you-go (AWS, Azure). • Private Cloud: Dedicated to one organization. • Hybrid Cloud: Mix of public & private. • Community Cloud: Shared by similar organizations.
- 6. Cloud Service Models • IaaS: Infrastructure as a Service – virtual servers & storage. • PaaS: Platform as a Service – development platforms. • SaaS: Software as a Service – ready-to-use apps.
- 7. Infrastructure as a Service (IaaS) • Example: AWS EC2, Google Compute Engine. • Control over OS, storage, networking. • Flexible and scalable.
- 8. Platform as a Service (PaaS) • Example: Google App Engine, AWS Elastic Beanstalk. • Developers focus on code, not infrastructure. • Reduces deployment complexity.
- 9. Software as a Service (SaaS) • Example: Gmail, Microsoft 365, Zoom. • Accessible via web browser. • Subscription-based pricing.
- 10. Benefits of Cloud Computing • Cost efficiency. • Scalability. • Accessibility from anywhere. • Disaster recovery. • Faster deployment.
