This document provides an overview of cloud computing, including its definition, history, service models (SaaS, PaaS, IaaS), and deployment models (private, public, hybrid). It discusses the engineering life cycle of cloud services, cloud migration, and benefits such as disaster recovery and rapid deployment. Additionally, it highlights key players in the industry and emphasizes the importance of planning and tool support for successful implementation.

- 9. What is Software as a Service? (SaaS) • SaaS is a software delivery methodology that provides licensed multi-tenant access to software and its functions remotely as a Web-based service.
- 10. Infrastructure as a Service (IaaS) • IaaS is the delivery of technology infrastructure on demand scalable service
- 11. Platform as a Service (PaaS) • PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet.
- 13. Private cloud : is cloud infrastructure operated solely for a single organization, whether managed internally or externally . these service use storage capacity and processor power that is not owned by the organization or business . Public cloud : is a style of computing where scalable and elastic IT-enabled capabilities are provided as a service to external customers using Internet technologies—i.e., public cloud computing uses cloud computing technologies to support customers that are external to the provider’s organization Cloud Deployment Models
- 14. Private cloud + Public cloud = HYBRID CLOUD Hybrid cloud : Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and dedicated services with cloud resources

- 28. CLOUD MIGRATION Cloud migration is the process of moving data, applications or other business elements from an organization's onsite computers to the cloud, or moving them from one cloud environment to another.
- 30. Concluding Remarks 1 • Cloud computing stimulates new research directions for new and novel ways of developing software & services • Proper planning and migration services are needed to ensure a successful implementation • Public and Private Clouds can be deployed together to leverage the best of both
- 31. Concluding Remarks 2 • Testing as a Service (TaaS) has a huge potential for Software Engineering in general and GSE in particular • need for process and tool support for migration and/or upgrade of applications and tools for cloud computing model
