Summary of the SATURN 2014 conference published on the SEI website.

Scott Hanselman Interviews Len Bass at SATURN 2014

Portland, Oregon native and well-known writer and blogger Scott Hanselman spoke at SATURN 2014 this year (“JaveScript, the Cloud, and the New Virtual Machine”) and, while there, he interviewed Len Bass for The Hanselminutes Podcast: Fresh Air for Developers. Len is a senior principal researcher at NICTA in Australia. During his long and distinguished career at the SEI, Len was co-author many seminal publications in the field of software architecture including Software Architecture in Practice.

In the podcast, Stories of Computer Science Past and Present with Len Bass, Len shares stories from his 40+ year career in software.

Transparency: An Architecture Principle for Socio-Technical Ecosystems
Felix Bachmann and Linda Northrop, Software Engineering Institute

Felix and Linda shared their experience as a team in the XSEDE project. They presented compelling evidence of the need to have transparent architecture and architectural practices in socio-technical ecosystems like XSEDE. XSEDE is a virtual, high-performance computer system that allows interactivity for scientists (e.g., biologists, mechanical engineers, environmentalists) all over the world to run their experiments. Experiments are usually of the types that need super-powerful computing capabilities. The system is distributed over a wide distance, and engineers or developers have different global and local priorities. Due to the size of the project and the high complexity, architectural guidance was necessary to ensure the success of the project. Felix’s and Linda’s team responsibilities are to help the team make the right architectural decisions, coach the team on how to incorporate architectural practices, and research missions.

Can You Hear Me Now? The Art of Applying Communication Protocols When Architecting Real-Time Control Systems
Todd Farley, BAE Systems, Inc.

BAE Systems deals with architecting real-time control systems. These systems are usually complicated and distributed. Also, the lifetimes of projects are usually very long. So BAE must always answer this question: Which process should they adapt? The problems they face tend to fall into three categories:

  • motion control systems (~robots)
  • computation-intensive algorithms
  • user interfaces

BI/Big Data Reference Architectures and Case Studies
Serhiy Haziyev and Olha Hrytsay, SoftServe, Inc.

Serhiy and Olha shared their experience with the tradeoff between modern and traditional (non-relational and relational) reference architectures. They looked into the challenges associated with each approach and gave tips from real-life case studies on how to deal with big data reference architecture. As a reminder, they visited some of the known big data challenges:

  • Data is generated from many and different sources.
  • As data grows, it becomes complicated and heterogeneous (velocity and volume) until it’s no longer manageable.

SATURN 2014 The Business of Software Architecture Session (notes)

Under N: Acceptance to Delivery in N Hours
Umashankar Velusamy, Verizon Communications, Inc.

Umashankar started the presentation with a simple question: Are all deliveries the same? Humans take about 9 months to “deliver” babies. Cats and dogs take about 2 months to do so. So not all deliveries are the same. In the software industry, the same thing applies—different deliveries take different amounts of time. However, we tend to apply a one-size-fits-all solution to everything. Umashankar asked another question: Does it make since to wait 2 weeks or even 2 months for something to deliver, when it takes only 12 hours to deliver? It’s definitely doesn’t make sense, Umashankar answers.

CORBA to Web Services Migration Using Model-Driven Approaches and Offshoring
Georg Huettenegger, Credit Suisse

Huettenegger discussed challenges and lessons learned from migrating one of the world’s largest and most successful CORBA SOAs to a web services SOA.

Credit Suisse is an integrated global bank. It delivers all the possible services that a bank could offer. Credit Suisse employs more than 45,000 people from 160 nations.

The current Credit Suisse SOA is “nice, yet limited.” Where it is headed is not good. It has over 2,500 CORBA service operations, there are 20–30 Mill CORBA calls per day, and there are about 400 consuming applications. With such a large scale and with such widely distributed employees, maybe Agile is not the way to go.

Impact of Architecture on Continuous Delivery
Russell Miller, SunView Software, Inc.

First, context: This was a greenfield, from-scratch project for a nontrivial social-monitoring tool. It was also their first attempt at the native cloud. It was a pilot for a truly agile project. Go to http://livepulse.co to see a beta version.

Miller uses the term “continuous delivery” (CD) as defined in Jez Humble’s book Continuous Delivery. It leverages continuous integration, automated testing, and automated deployment. Releases are frequent, small, and predictable.

For example, take Amazon drone delivery. It eliminates waste, and customers do not have time to cancel the order. It also provides quicker feedback from the customer. So CD vs. the traditional release model is similar to drone delivery vs. freight train delivery. “This is a good metaphor for lean vs. legacy.”

SATURN 2014 Awards Conferred

Since 2010, the SEI and IEEE have been conferring two attendee-selected awards at SATURN. The IEEE Software SATURN Architecture in Practice Presentation Award is given to the presentation that best describes experiences, methods, and lessons learned from the implementation of architecture-centric practices. Anthony Tsakiris of Ford Motor Company, Jeromy Carriere of eBay, Inc., Michael Keeling of Vivisimo, and Simon Brown of Coding the Architecture received this award in 2010, 2011, 2012, and 2013 respectively. This year’s award winners were Will Chaparro and Michael Keeling of IBM for their presentation titled Facilitating the Mini-Quality Attributes Workshop.

Expanding Legacy Systems Using Model-Driven Engineering (MDE)
William Smith, Northrop Grumman
Kevin Nguyen, Northrop Grumman

Kevin Nguyen and his fellow engineers faced a common problem of dealing with legacy systems. At their environment (Northrop Grumman), they are dealing with rigid defense systems. Kevin tried to adapt a model-driven engineering approach in his work to achieve his goals. The team used conceptual software architecture to help understand customer requirements. Next, they refined the requirements into a CSCI architecture of software and hardware. Then, they tried to expand the CSCI architecture into CSC architecture (more detailed and lower level models). Finally, the team tried to convert that into a detailed design for the software unit. They went through these steps following a basic procedure of software-design life cycle.
