Understanding Cloud Computing: History, Characteristics, and Service Models

DESCRIPTION

This presentation by Jeremy Olson provides a comprehensive overview of cloud computing, discussing its definition, historical context, and essential characteristics such as on-demand self-service and resource pooling. It explores various service models including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Additionally, it examines deployment models like private, public, and hybrid clouds, and highlights commonly used services such as Google Chrome OS, Dropbox, and Amazon Web Services. A valuable roadmap for understanding the cloud landscape.
