Introduction to Cloud Computing - What is SAAS , PAAS, and IAAS

The video tutorial explains the three main types of cloud services: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). SaaS allows users to access applications via a browser without installation, with examples like Gmail and Office 365. PaaS provides developers with backend services to create and manage applications without handling infrastructure, using databases like Postgre or Oracle. IaaS offers virtualized infrastructure components like servers and firewalls, enabling users to provision resources without physical hardware.
