Covering essential service models like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), it delves into deployment models (public, private, hybrid, and multi-cloud), major cloud providers (AWS, Microsoft Azure, Google Cloud), security concerns, and practical applications across industries.
