Join our industry-heavyweight (eBay, Betfair, FiveRuns and Twitter) panel as they explore the cost of making their sites as scalable as possible, whilst tuning to get the most performance they possibly can. They explore the pros-and-cons of making their apps as awesome as possible - all the while under the pressure of their business requirements.
Roberto Zicari, from ODBMS.org, collected interviews and stories from several users of Object/Relational mapping technologies. The main point of the cases was around "impedance mismatch" between the object technology in the domain model and the relational technology in the data model.
Many important challenges faced by a software architect for a large company have as much to do with the organization as technology. In a recent blog entry, Dan Greenblog drew parallels between the principals behind software architecture and effective organizational structures.
Mat Wall and Nik Silver explain how their has been using Domain-Driven Design in an evolving and Agile environment, at high traffic news site guardian.co.uk.
While virtualization provides many benefits, security can not be a forgotten concept in its application. This new article takes a look at how virtualized servers effect data center security.
In this interview, Avi Bryant talks about the Smalltalk web framework Seaside, DabbleDB, using Smalltalk images for persistence instead of an RDBMs, GemStone and more.
In this interview, Billy Newport talks about different types of virtualization, eXtreme Transaction Processing (XTP) and how WebSphere products like Virtual Enterprise (formerly XD) support virtualization. He discusses hardware, hypervisor, JVM, application and data virtualization.
Although nearly everyone acknowledges the importance of user experience, usability often ends up pushed to the back of the queue. How then can we know whether what we are delivering makes sense and will work for our users? This presentation shows an approach to usability, focusing on activities in which users engage offers the potential for delivering dramatic improvements with much less effort.
In this talk, Markus Völter illustrates how model-driven and aspect oriented software development help addressing the challenge of managing variability in product line engineering. Both the problem space and the solution space are described by models, using a model-to-model transformation to map problem space variability to solution space variability.
Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
Domain Driven Design is a vision and approach for designing a domain model that reflects a deep understanding of the business domain. This book is a short, quickly-readable summary and introduction to the fundamentals of DDD; it does not introduce any new concepts; it attempts to concisely summarize the essence of what DDD is, drawing mostly Eric Evans' book, as well other sources since published such as Jimmy Nilsson's Applying Domain Driven Design, and various DDD discussion forums.
