Chapter 3 Diving into Cloud  Economics In This Chapter M any companies today are expanding into cloud computing as a way to reduce the cost and complexity  of delivering traditional IT services. But determining the best  mix of public and private cloud services and data center services is complicated. You can’t simply add up specific  costs and make a fast determination of what’s the best  approach for your organization. Instead, you have to look at  your business requirements for performance, availability,  and security and the workloads that you need to support.  A  workload  is an independent service or collection of code  that can be executed. You have to look at services such as  Infrastructure as a Service (IaaS), Platform as a Service (PaaS),  and Software as a Service (SaaS) in context with your business  goals and the impact on the customer experience. In this chapter, you examine both the indirect value factors  that affect the economics behind IaaS and PaaS models as well  as the direct cost factors.
