SEI Architecture Technology User Network (SATURN) News and Updates

When we attend technical conferences, the sessions we appreciate most and remember long after the conference ends are those in which influential, creative thinkers share and explore ideas that excite them. If you have had this experience at conferences you have attended, you'll agree: when a gifted speaker expands minds by challenging well-worn assumptions and articulating groundbreaking ideas, you can feel the energy in the room.

Because we wanted this experience at SATURN 2015, both for ourselves and for our attendees, we invited some of the most influential thinkers in the field of software architecture to participate in the conference program. And not only did we invite a collection of people we knew would electrify a room with their ideas; we also asked them to curate their own sessions by inviting additional speakers who have inspired them. The result: we are pleased to introduce the Invited Speakers Series, new this year at SATURN 2015.

Billions and Billions Served: Real-Time Distributed Messaging

Dissecting Message Queues: Tyler Treat at Brave New Geek reports an analysis of several different message queues and describes the differences in throughput and message latency between brokered systems (such as NSQ) and brokerless systems (such as ZeroMQ). Graphs of his results may provide information about which type of system is best for different contexts and needs.

NSQ: A Realtime Distributed Messaging Platform: Bitly developers Matt Reiferson and Jehiah Czebotar have designed NSQ to "operate at scale, handling billions of messages per day." It serves as the backbone of an infrastructure composed of loosely connected services running on many computers. With no single point of failure, it has high availability, reliability, and fault tolerance. For use with any data format, NSQ is easy to configure and deploy.

The Fun of Experimenting with a More Advanced Microservice Application - Building a Slack "Done This" Tracker: Ad Van der Veer at Giant Swarm explains how he used NSQ as one of three components of a method to manage complexity in the architecture layer of a microservice setup.

Second International Workshop on Software Architecture and Metrics at ICSE

http://www.sei.cmu.edu/community/sam2015/

We are pleased to announce the program for the Second International Workshop on Software Architecture and Metrics (SAM 2015) featuring keynotes from Radu Marinescu and Tim Menzies, invited presentations on architecture quality and measurement, and interactive sessions to discuss progress on architecture and metrics, measurement, and analysis; to gather empirical evidence on the use and effectiveness of metrics; and to identify priorities for a research agenda.

The workshop addresses both academic researchers and industrial practitioners for an exchange of ideas and collaboration. The workshop will be held in conjunction with the International Conference on Software Engineering (ICSE 2015), May 16-24, 2015 in Florence, Italy.

For more information and to participate, see the Workshop Program.

The 12th SEI Architecture-Centric Engineering Workshop for Educators will be held at the Software Engineering Institute in Pittsburgh, Pennsylvania, USA, on August 3-5, 2015. The SEI hosts this annual event to foster an ongoing exchange of ideas among educators whose curricula include the subjects of software architecture and software product lines. The event is free of charge and open to any accredited, college-level educator.

This year's event will incorporate the SEI's course on DevOps from a Software Architecture Perspective. This course is helpful if you wish to adopt DevOps practices and continuous-delivery workflows. The architecture component of the course focuses on the relationships among application software, the deployment environment, and the supporting tooling.

WICSA | CompArch 2015 workshops provide a unique forum for researchers and practitioners to present and discuss the latest R&D results, experiences, trends, and challenges in the field of software architecture, component-based software engineering, and software system qualities.

At SATURN 2015, to be held in Baltimore, Maryland, April 27-30, 2015, the SEI will augment the three-day technical program with three one-day courses offered on Monday, April 27. SEI courses are created and delivered by recognized experts who have practical experience in the disciplines they teach. Our courses feature participatory tasks and real-world scenarios to enhance your learning

Big Data: Architectures and Technologies (instructors, Ian Gorton and John Klein) Scalable big-data systems are significant long-term investments that must scale to handle ever-increasing data volumes, and therefore represent high-risk applications in which the software and data architectures are fundamental components of ensuring success. This one-day course is designed for architects and technical stakeholders such as product managers, development managers, and systems engineers involved in the development of big data applications.

Software Architecture Modeling
Last summer, a Mother Jones article by Tasneem Raja asked, "Is coding the new literacy?" The answer is yes and no, because the point is not to increase "the number of kids who can crank out thousands of lines of JavaScript" but "to boost the number who understand what code can do" and can think up good ways to apply it. To do this, computer science education must first undergo a paradigm shift, from "reinforcing the notion that code is just for coders" to leading with computational thinking, which CMU's Jeannette Wing defines as "solving problems, designing systems, and understanding human behavior."
