Content Outline
PreviewUnit 827: Cloud Computing Fundamentals and Infrastructure
1. Introduction to Cloud Computing
- Definition and evolution of cloud computing
- Key characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service
- Benefits of cloud computing: cost efficiency, scalability, flexibility, and accessibility
- Cloud service models:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
2. Cloud Infrastructure Components
- Servers: physical vs. virtualized
- Storage systems: block storage, object storage, file storage
- Networking in the cloud: virtual networks, load balancing, DNS
- Virtualization technologies overview
