cloud computing is delivered through three service models: SaaS, PaaS, and IaaS, and deployed through four models: Public, Private, Hybrid, and Community. Each model carries its own security implications. SaaS requires vigilance around data security, integrity, segregation, locality, access, and especially authentication and authorization. IaaS, while offering greater control, demands careful management of virtualization, physical security, and data transmission. Understanding these risks is essential for any cloud architect or security professional. Thank you for watching."
