Part 3 Part 3 Architecture In this part, we describe the architecture for the Smart Analytics Cloud: We give an architecture overview and describe how the cloud fits into a larger enterprise context. We drill down in Chapter 6, "Functional architecture" on page 63, into a functional architecture of the cloud and the rationale behind using it. We describe the functions that are required not only for the IBM Cognos 8 BI components, but also for the onboarding functionality that is used as an approach self-service access to IT functionality. In Chapter 7, "Operational architecture" on page 73, we give an operational architecture overview of the cloud that shows how the required functions are placed on actual infrastructure and which technology is chosen. We look into the systems management aspects, which ensure the vitality and the automation of the cloud. © Copyright IBM Corp. 2010. All rights reserved. 45
