Cloud computing and Cloud Enabling Technologies
The document discusses cloud computing and its essential characteristics, which include on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. It outlines various cloud service models, including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Additionally, it covers enabling technologies such as virtualization, grid computing, and the Internet, highlighting the benefits and challenges of these technologies.

- 16. Hardware/ Virtualization • Creationof a VM that acts like a real computer with an OS. • Platform virtualization has two different models: • Type 1 – Bare metal • Type 2 – Hosted. Full virtualization Paravirtualization

- 18. Paravirtualization (PV • PVis an efficient and lightweight virtualization technique introduced by the Xen Project team. • PV does not require virtualization extensions from the host CPU. However, PV guests and control domains require kernel support. • In PV, the hardware environment is not emulated; however, the guest programs are executed in their own isolated domains.
