Best of SATURN: A Curated Selection from Jeromy Carriere (Google)

Jeromy Carriere of Google, member of the SATURN 2014 Program Committee and previously featured speaker at SATURN, dug through presentations from previous years at SATURN and put together a list of some he found valuable:

Invited talk: Games Software Architects Play (Phillippe Kruchten)
“The life of a software architect is a long (and sometimes painful) succession of suboptimal decisions made partially in the dark.” Phillippe takes us on a tour of some of the ways that we make bad decisions: cognitive biases, reasoning fallacies, political games. Sadly, each example resonates with me, and not just because I’ve seen them in other people. Architects have to rely on intuition, but we also need to know when and how it fails us.

SATURN 2014 Call for Submissions

SATURN 2014 marks the 10th Software Engineering Institute (SEI) Architecture Technology User Network (SATURN) conference—the largest conference dedicated to software architecture in North America. Since 2003, an international audience of practicing software architects, industry thought leaders, developers, technical managers, and researchers have gathered at SATURN to share ideas, insights, and experiences about effective architecture-centric practices for developing and maintaining software-intensive systems.

SATURN 2014 will take place in Portland, Oregon from May 5—May 9, 2014.

Migrating Legacy Applications: Challenges in Service Oriented Architecture and Cloud Computing Environments

As the future of software development in a global environment continues to be influenced by the areas of service-oriented architecture (SOA) and cloud computing, developers will need to migrate many legacy applications to these environments to take advantage of the benefits offered by the service environment.

SATURN 2013 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., and Michael Keeling of Vivisimo received this award in 2010, 2011, and 2012 respectively. This year’s award winner was Simon Brown of Coding the Architecture for his presentation titled The Conflict Between Agile and Architecture: Myth or Reality.

SATURN 2013 Mobile Computing Session (notes)

Notes by Frank M. Rischner

Architecture Patterns for Mobile Systems in Resource-Constrained Environments
Grace Lewis, Jeff Boleng, Gene Cahill, Edwin Morris, Marc Novakouski, James Root, and Soumya Simanta, SEI

First responders, soldiers, and other front-line personnel work in resource-constrained environments. It is necessary to use mobile systems in those environments. The systems are limited in performance and battery life.

This talk is about architectural patterns. The first pattern Lewis talked about is the Data Source Integration Pattern, which means the data source is on the server. Some of the operations on the data are very power consuming, so we don’t want them on the mobile device. The user defines the filters on the mobile device and sends them to the server. The second pattern is the Group Context Awareness Pattern. The users don’t go out in the field alone. The users’ devices are connected to the same controller, so all devices show the same view. Since the users are not in the field alone and probably operate in a close area, only one device needs the GPS has to be turned on. This model is a layered MVC pattern. Rule sets apply to the mission and are interchangeable. The third pattern is the Cloudlet-Based Cyber-Foraging Pattern. Cyber-foraging has been around for a while; the most known application is probably Siri from Apple. The Cloudlet-Based Cyber-Foraging base is on a VM manager.

SATURN 2013 Web and Cloud Architecture Design Session (notes)

Notes by Frank M. Rischner

The Design Space of Modern HTML5/JavaScript Web Applications
Marcin Nowak and Cesare Pautasso, University of Lugano

Whenever we create a web application, we have to decide where the application runs, either on the server side or on the client side. When using HTML5, we push everything but the data to the client.

In the example scenario, the server is treated as the database, and the browser is seen as a terminal. There are several Model View interaction patterns: Model View Controller Pattern, Model View Presenter Pattern, and Model View ViewModel Pattern, which is the most flexible one of the patterns. Most recent movements apply the “Model View *” pattern, which leaves out the controller.

BestBuy.com’s Cloud Architecture
Joel Crabb, Best Buy, Inc.

Crabb works for BestBuy, the world largest multi-channel consumer.

In 2010, BestBuy built a team to experiment with cloud components. Smaller web properties have been stored in the cloud. Also, the test environments have been put in the cloud.

SATURN 2013 Keynote Address: 15 Years of SOA at Credit Suisse: Lessons Learned and Remaining Challenges, Stephan Murer

Notes by Frank M. Rischner, Ian De Silva, and Brendan Foote

SATURN 2013 Keynote Address: 15 Years of SOA at Credit Suisse: Lessons Learned and Remaining Challenges

Stephan Murer, Credit Suisse

Murer works for Credit Suisse, which finds competitive advantage in creating their own systems, rather than outsourcing that work to software vendors. The company handles a large-scale user base, with almost 67,750 users in 550 locations. The data is managed and stored in four main data centers. Currently, Credit Suisse manages about 6,400 applications as well as about 70,000 email accounts. The volume of the applications developed in-house is about 200 million lines of code. The number of managed applications at Credit Suisse is of course lower than in any app store, but the focus is more on the integration of the applications. The largest scalability concern Murer sees coming is storage, for example, if regulators require them to start recording video conferences for compliance reasons.

5th International Workshop on Principles of Engineering Service-Oriented Systems (PESOS 2013)

5th International Workshop on Principles of Engineering Service-Oriented Systems (PESOS 2013)
in conjunction with ICSE 2013, San Francisco, CA, U.S.A.
May 26, 2013
http://www.sei.cmu.edu/community/pesos2013/

Registration for PESOS 2013 is open. Take advantage of early-bird rates until April 14, 2013.

Background

Service-oriented architecture (SOA) and service-oriented systems, which are built using the SOA paradigm, are now in the stage of widespread adoption, according to Gartner’s Hype Cycle of Emerging Technologies. Influenced by the stabilizing of certain standards for service integration, and driven by IT cost savings, organizations are starting to incorporate external software services into their systems. Some of these services are hosted in the cloud. From a provider perspective, many commercial companies such as Oracle, SAP, Intuit, and Netflix either have cloud-based offerings of their products or run their businesses completely in the cloud.

SATURN 2013 Program Highlights from Conference Program Chairs

As program chairs for SATURN 2013, we would like to provide you an overview of the presentation program (note: information about keynotes by Stephan Murer, Scott Berkun, and Mary Poppendieck, the invited talk by Philippe Kruchten, and tutorial highlights is already available in other blog posts).

We received many high quality submissions covering the topics of front-end architecture, back-end architecture, methods and tools, and technical leadership. In total we got contributions from more than 40 companies and organizations across three continents.

On Wednesday morning you have the tough choice to decide between three great sessions. For example, Harald Wesenberg from Statoil speaks about architecting for the long term in Session 1. In Session 2, Chris Armstrong presents ISO/IEC/IEEE 42010 in action, while Session 3 deals with agile practices at scale.
