Case Studies

As described in the previous chapters, the CloudScale method lets software architects manage scalability, elasticity, and cost-efficiency throughout the whole system lifecycle. To illustrate its usage, this chapter describes an application of the CloudScale method and its tools on two industrial case studiesCase studies. The first case study—Ericsson’s Electronic Health Record (EHR)EricssonElectronic Health RecordEHR see Electronic Health Record—is an electronic health record software, and the second one—Kantega’s Flyt CMSKantegaFlyt CMS—is a content management system (CMS). The case studies exemplify scenarios that require an engineering approach to ensure the system is scalable and performs well. The providers of the stated industrial cases are different organizations that follow their own internal development processes. The chapter closes by briefly pointing to complementing case studies that were used to evaluate the CloudScale method, both separately and in the context of the CloudScale method.The following sections cover the essential steps and tools in the CloudScale method for the Electronic Health Record (EHR) (Sect. 9.1) and Flyt CMS (Sect. 9.2) case studies. Subsequently, the complementing case studies are overviewed (Sect. 9.3).
