Full Explanation
Infrastructure as a Service supplies virtualized compute, storage, and networking while customers install and operate higher layers such as Hadoop. That matches a city that builds its own Big Data stack on cloud VMs. SaaS delivers finished applications; PaaS abstracts frameworks further so teams mainly deploy code. Recognizing IaaS among Chapter 9 service-range models is required BDPC awareness for cloud-hosted Big Data.
