Scalability engineering is currently not well integrated into agile development techniques. This paper extends agile development techniques so that scalability can be handled in an incremental and iterative development process. By scalability we mean the ability of a system to handle increasing work...

Semantic container management is a promising approach to organize data. However, the scalability of this approach is challenging. By scalability in this paper, we mean the expressivity and size of the semantic data containers we can handle, given a suitable quality threshold. In this paper, we deriv...

Cloud computing theoretically offers its customers unlimited cloud resources. However, the scalability of software services is often limited by their underlying architecture. In contrast to current scalability analysis approaches, we make work parameters, quality thresholds, as well as the resource ...

This paper describes CloudStore, an open source application that lends itself to analyzing key characteristics of Cloud computing platforms. Based on an earlier standard from transaction processing, it represents a simplified version of a typical e-commerce application – an electronic book store. We...

Having described the CloudScale method for engineering scalable cloud computing applications in the previous chapters, we explicitly address managers of software development processes in this chapter. It answers questions managers have in mind when considering the CloudScale method: Is it worth impl...

Architectural analysis describes the activity of discovering important system properties—like functional requirements and service-level objectives (SLOs)—using models of the system. The main benefit of such analysis is that software architects can assess their design and what-if scenarios without ha...
