Research the "as-a-service" type of approach to cloud computing while considering Software as a Service (SaaS), Identity as a Service (IDaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). How can these approaches reduce costs and add value?

Specific attention should also be given to the (SaaS) cloud model. How can this model reduce costs and add value to collaboration services like Web mail, messaging, file share, and project management?

Include in your analysis a discussion on Identity as a Service (IDaaS). How would IDaaS integrate with the on-premise solutions for human resources, supply chains, and collaboration services in a SaaS solution?
