Notes by Ziyad Alsaeed, edited by Tamara Marshall-Keim 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.

Notes by Ziyad Alsaeed, edited by Tamara Marshall-Keim 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.

Notes by Scott Shipp, edited by Tamara Marshall-Keim 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.

Notes by Scott Shipp, edited by Tamara Marshall-Keim 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."

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.

Notes by Ziyad Alsaeed, edited by Tamara Marshall-Keim 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.
