Cloud Computing
The cloud metaphor is used to represent efficient, elastic, scalable and reliable computational infrastructures Provisioning of resources (server, storage, applications … whole IT infrastructures) via services and web-applications over the network Outsourcing data and applications to external service providers Replacing classical desktop software with web-based applications

Cloud Computing
www.52north.org/security
Categories Software as a Service (SaaS)
- Dyncamic Software and data provisioning (outsourcing, on-demand) - Allows pay-per-use revenue models
Platform as a Service (PaaS)
- Software development and deployment platform - Quality of Service, QoS (scalability) managed by cloud provider
Infrastructure as a Service (IaaS)
- Virtualized and dynamically managed (elasticity) IT infrastructure - Dynamic resource (server, storage) provisioning (ondemand) - Delivers computational infrastructures as services over the network
