Games for the Masses - How DevOps Affects Architecture Design
Jesper Richter-Reichhelm presents the DevOps integration at Wooga, and how their system architecture has evolved over the years in order to cope with the increasing number of players.

In a recent and provocative article for SD Times David Rubinstein emphasizes his opinion that while SOA has gained a lot of momentum as an architectural principle, it might be dead as a term. He quotes analyst Jason Bloomberg, who considers SOA as a bad word. In his opinion, SOA as a technology has already died due to Cloud Computing and the intrinsic complexity of Web services.
Phusion has released a preview release of their upcoming 3.2 version of Phusion Passenger. Version 3.2 comes with a re-written ApplicationPool, I/O handling is now event-driven and the Python support became a first-class citizen.
Microsoft recently announced RTM release of WCF Data Services 5.0 – this includes several new features to support OData v3 such as Vocabularies, Actions, new Spatial Primitives and several updates to OData libraries.
Article “Purpose Case Management” describes a Case Management method that overarches BPM and Adaptive Case Management. Author reviews several modern movements such as Unstructured BPM, Social BPM, Dynamic BPM, and ACM. The article concludes with a generic method that allows switching between BPM and ACM depending on which one of them is more efficient in an execution context at certain moment.

In this IEEE article, author Mark Harman talks about evolutionary computation and how it has affected software design. Main focus is on search-based software engineering (SBSE), which focuses on the application of search-based optimization techniques to problems in software engineering. Mark also discusses the application of SBSE in emerging areas such as cloud, mobile and embedded systems.

In February, we launched the 2012 InfoQ User survey to gauge community interest in various topics, technologies, and practices. 2,850 people completed the survey, with thousands of respondents providing detailed feedback on their areas of interest. The following report summarizes some of our key findings, things that surprised us, and reactions/analysis from members of the InfoQ editorial team.
Mark McGranaghan presents how Heroku has designed, developed and operated cloud services providing high availability for their PaaS.
Stefan Tilkov suggests breaking a system into several subsystems, separating the micro and macro architecture, and addressing various integration issues in order to get a suppler architecture.

Martin Thompson and David Farley discuss how to use the scientific method to create high performance systems by measuring performance and adapting the implementation to approach the limits of current hardware. The disruptor architecture is an open sourced result of their work at low-latency, high throughput systems for the retail trading platform of LMAX Ltd.

In this interview done by InfoQ's Srini Penchikala, Oleg Zhurakousky talks about the cloud architectures with messaging as the core part of the cloud solutions. He also discusses the Spring Integration and other Spring projects like Spring Roo and Cloud Foundry.

This is the first edition of what is expected to become a recurring series on InfoQ. The idea behind this minibook is that a number of InfoQ articles and interviews which deal with a particular topic (in this case, REpresentational State Transfer, or REST) are combined together to provide a detailed exploration suitable for both beginners and advanced practitioners.

"Getting Started with Grails" brings you up to speed on this modern web framework. Companies as varied as LinkedIn, Wired, and Taco Bell are all using Grails. Are you ready to get started as well?

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.

Within this book you will find everything you need to get up and running using Struts2 – from the architecture and configuration, to implementing actions and the supporting infrastructure such as validation and internationalization. Above all else, it focuses on the practical – with plenty of code and productivity tips to get you started using Struts2 today.

Grails is an open-source, rapid web application development framework that provides a super-productive full-stack programming model based on the Groovy scripting language and built on top of Spring, Hibernate, and other standard Java frameworks. Over the course of this book, the reader will explore the various aspects of Grails and also experience Grails by building a Grails app.

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.

This book argues that for SOA to succeed we must move our thoughts away from the implementation technologies and towards the "what" of the business. Using a straight-forward, pictorially driven, methodology the book explains who to discover what the business services really are and how to construct an overall business service architecture.
