Cloud Computing Models and Services

The video tutorial explains various cloud computing models, including Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS). It details the responsibilities and benefits of each model, such as hardware outsourcing in IaaS, application management in SaaS, and development tools in PaaS. The tutorial also covers different cloud deployment models like public, private, and hybrid clouds, and introduces Desktop as a Service (DaaS), highlighting its minimal hardware requirements and the need for sufficient bandwidth.

What is the primary responsibility of the user in an Infrastructure as a Service (IaaS) model?

• Managing the hardware

• Providing network infrastructure

• Loading applications and managing data security

Which cloud model involves outsourcing hardware while still managing applications and data?

• Hybrid cloud

• Software as a Service (SaaS)

• Infrastructure as a Service (IaaS)

• Platform as a Service (PaaS)

Which of the following is NOT a characteristic of Software as a Service (SaaS)?

• Users manage the infrastructure

• The service provider manages data security

• No need for users to develop software

• Applications are accessed via a web browser

What is the main advantage of using Software as a Service (SaaS) for businesses?
