The Art of Scalability teaches technology executives, engineers and architects how to solve technology scalability problems through changes in their architecture, processes and organization structure.

The book provides a set of models and approaches that help back office, web services and other platforms scale. Rather than focusing on the optimization and tuning of existing systems, the book offers models developed by the authors to help companies rethink their technology architecture.

AndroMDA is an MDA framework for transforming models (usually UML models stored in XMI produced from casetools) using a combination of plug-ins (cartridge and translation libraries) and to produce custom components.

• A very important thing to know about AndroMDA is that the transformation process is controlled using plug-ins called cartridges and each cartridge is very easy to tune.
• AndroMDA was developed to help eliminate boring and repetitive tasks, while at the same time allowing a model to really communicate what the system is doing: it is not meant be a Silver Bullet solution
