"Just Enough Software Architecture book, by author George Fairbanks, focuses on a risk-driven approach to software architecture development. RelatedVendorContent Got fires in production? Find root cause in minutes. FREE Java performance tool The Agile Business Analyst Experience Java EE! 600 page Redbook Testing Platforms Analyst Comparison: IBM, Microsoft, Coverity, MKS, and more Transform IT Complexity to Achieve IT System Vitality George explains the Architecture Modeling process from different perspectives such as Engineering Use Models, Conceptual Model, Domain Model, Design Model and the Code Model. He also discusses the various architecture styles including Big ball of mud, Pipe-and-filter, Batch-sequential, Map-Reduce and talks about the distinction between architectural patterns and architectural styles. The discussion also includes topics like evolutionary design, architecture refactoring and how to analyze, test and validate the architecture models."

"Agile development starts to build before the outcome is fully understood, ad­justs designs and plans as empirical knowledge is gained while building, trusts the judgment of those closest to the problem, and encourages continual col­laboration with the ultimate consumers. Architecture establishes a technol­ogy stack, creates design patterns, enhances quality attributes, and communicates to all interested parties. The combination of these two spaces is agile architecture - an approach that uses agile techniques to drive toward good architecture. Successful agile architecture requires an architect who understands agile de­velopment, interacts with the team at well-defined points, influences them using critical skills easily adapted from architectural experience with other approaches, and applies architectural functions that are independent of project methodology."

" A number of commentators have been talking about the perceived dichotomy between Agile techniques and architectural thinking. In the Agile world architecture is often perceived as BDUF (Big Up Front Design) and as a result is frequently overlooked or delayed in the spirit of "YAGNI" (You ain't gonna need it)."

" Kevlin Henney promotes live architecture through refactoring, recovery, re-envisioning, retrospection, re-engineering, repair, rewriting, reduction, reuse, reaction, re-evaluation and remembering. "

Sounds like this guy is confuse between enterprise architecture and solutions architecture. Or I am. :)

I think both those roles are evolving quite quickly at the moment. The classic Enterprise Architect is having to find new ways to plan, communicate and check quality as more and more teams explore Agile methodologies. The Solution Architect is suddenly playing a more obvious role as a result of the above. My feeling is, it is not so much about people, but about function. The same person could operate as a Solutions Architect most of the day, but then could get together in some kind of Architect's forum and play the role of an Enterprise Architect. That forum then wrestles through the Enterprise Architect issues and establishes the back-bone on which the Agile Development is done. That's what is probably happening, formally or informally in a lot of dev teams at the moment.

"Agile development methods attempt to improve the software development process, so that we can deliver useful solutions more often, and more quickly. However, despite some successes larger organisations and projects have been very slow to adopt them. One of the reasons is that many agile methods are perceived as architecturally weak, disconnected from the realities of delivering large systems in complex enterprise environments."

"Datomic is a new database designed as a composition of simple services. It strives to strike a balance between the capabilities of the traditional RDBMS and the elastic scalability of the new generation of redundant distributed storage systems."

" This guide is focused on building highly scalable, highly available, and maintainable applications with the Command & Query Responsibility Segregation and the Event Sourcing architectural patterns. It presents a learning journey, not definitive guidance. It describes the experiences of a development team with no prior CQRS proficiency in building, deploying (to Windows Azure), and maintaining a sample real-world, complex, enterprise system to showcase various CQRS and ES concepts, challenges, and techniques. The development team did not work in isolation; we actively sought input from industry experts and from a wide group of advisors to ensure that the guidance is both detailed and practical. "

"Jason Baragry from the Norvegian Computing Center asked me to comment on the relationship bettween MOP and DCI. I originally threw a few comments here. I wanted to go back and comment some more after watching James Coplien's latest video from QCon. James really ticked me off. He embodies -like so many self-proclaimed gurus- what is so wrong with our industry."

" Ian Robinson considers that programming for the web requires a different architectural approach than for applications: clients are interested only in URIs, clients are responsible for the integrity of a sequence of requests, and one should implement application protocols as protocol resources , not domain resources. "

" Siddharth Anand overviews Netflix's business model, then he explains why they chose Amazon AWS, and how they moved their data into the cloud using a NoSQL solution. "

Udi Dahan shows you how to use the fabulous NServiceBus to provide reliable messaging using both a request/response and publish/subscribe architecture. He shows how much easier it is to use NServiceBus than to use WCF for reliable messaging.

"Do you need to get your Java-based and .NET-based components to work together? JNBridgePro allows you to connect anything Java to anything .NET, anywhere: whether your components are running in the same process, across a network, or in the cloud. JNBridgePro's high-performance bridging architecture removes the complexities of cross-platform interop; you can generate a solution within a day - instead of weeks. "

" Object-oriented programming was supposed to unify the perspectives of the programmer and the end user in computer code: a boon both to usability and program comprehension. While objects capture structure well, they fail to capture system action. DCI is a vision to capture the end user cognitive model of roles and interactions between them. "

"There are sufficient videos available in the video repositories provided by YouTube and Vimeo to make it difficult locating the good ones. In addition, not all of them are professionally produced. However, InfoQ.com could identify some pearls which are worthwhile watching. We have reviewed what we found and tried to figure out the interesting ones. But, of course, such activities are always driven by the author's taste."

"distributed-computingWe've had a lot of success applying the principles and practices of the Advanced Distributed Systems Design course into our project and Udi Dahan asked if I could shed some more light on how things played out for us, so here it is."

"In my consultant career, no matter the kind of company I visited, from the tiny startup to the largest fortune 500 corporation, they all have in common to be entangled in spaghetti. Spaghetti means poorly structured code. Spaghetti means high maintenance and evolution cost. Spaghetti means frustration, friction and lack of motivation for everyone in the team. And often, spaghetti means project failure."

"In this walkthrough I'll guide you through the steps of configuring a development environment for Service Bus for Windows Server (Service Bus 1.0 Beta) and creating a simple application. This post is a condensed version of the contents from previous link. If you'd rather to read the whole document, you are welcome to do so. On the other hand, if you prefer a shorter version with step-by-step guidance, please read on! Throughout the post we'll also touch upon key concepts you need to understand to manage and use Service Bus. So, if you learn better with hands-on experiments, this is a perfect post (I hope) for you to get started. "
