The Industry Day at ECSA 2014 brought together researchers and practicing architects from local, European and worldwide communities who shared best-practices, pitfalls and their professional experiences in designing, implementing and reviewing software architectures. Keynotes and invited talks featured lessons learned and best practices from enterprise-scale industry projects; furthermore there were interactive formats such as a panel discussion and an open space session.
With this program, Industry Day at ECSA 2014 helped bridge the gap between academia and industrial practice by establishing an open communication and discussion environment. The ECSA 2014 Industry Day offered researchers and practitioners the opportunity to get in touch with fellow professionals and go home with new ideas and skills for industrial problems, research proposals, or validation opportunities.

P1.1 Enriching legacy systems. A field report about the architectural work on performance critical and long-living software.
Slides
Continuous development and redesign of software with a multi-decade product life cycle is always a challenge. However, the situation gets worse for performance critical software that runs on a multitude of platforms including high-end servers, modern smart phones and embedded devices. Whilst working on such a project, namely the integration of an open-source rendering engine into the (remote-)display software of construction machines, we gathered interesting findings that are of practical importance for software architects. These findings incorporate design transitions from procedural development to object-orientation, compile-time configuration versus runtime configuration, and the harmonic integration of new features into embedded software systems without breaking the old ones.

P1.2 Service Development and Architecture Management for an Enterprise SOA
Slides
We report on service development and architecture management practices in an enterprise SOA for the financial domain. We first describe how services are currently developed by one of the largest service providers for the financial domain in Austria. We then show how we have introduced various practices and tools for architecture management over the last years. Specifically we focus on support for architecture analysis and review as a means for quality control on this area. Finally, we report on lessons learned both in the area of service development and architecture management as well as on existing challenges and future work in this area.

P2.1 Adaptable Software Architecture
Slides
Change lies at the heart of software. That is a given no one in the field would dare to conquer. Why then is so hard to adapt a software and its architecture when business requirements change?
There are various definitions of what software architecture is, and none of them offers any helpful advice on how to build true software that is robust and open to change: “Architecture is about the components that comprise a software system, and the relations among them.” “Architecture is a framework for change.” “Architecture is about decisions that are hard to change later.“
The truth is that change happens on every level. And since you don’t know what might possibly change, you must be prepared for fundamental changes at any time.
So, how do we deal with change – change that is ubiquitous, change that can range from small to large scale, change that can shake the foundation of your whole software system, change that doesn’t stop at the architecture that you crafted so meticulously?
In this session Reto Carrara talks about the challenges of building and maintaining software systems that are adaptable to change without decay and software rot. He lays out why even the most fundamental components of software systems commonly referred to as software architecture change over time. He offers insight on how to deal with such changes by leveraging the benefits of Domain Specific Modelling and automatic code generation, a proven way to build and maintain adaptable software systems.

P2.2 Modeling Principles – A survey of current modeling approaches in industry and where the journey may go
Slides
Modeling is nothing new, languages like UML, SysML and BPMN are already well known and used in the industrial practice. However, there is a huge gap how modeling is applied in the industry. Models are used just as pictures and providing a documentation. On the other hand, models became first class citizen and are the main artifacts to generate code or even complete systems.
This talk gives an overview of the current state of the art in modeling approaches used in the industry. It gives insights what is currently going well, what is still missing in the industrial practice and gives an outlook of how modeling approaches may look like in future.

P3.1 API Management: A new Model for Delivering Applications in a Multi-Device World
Slides
API Management stands for a new, flexible approach in IT. The main idea is that enterprises deliver technical services (APIs, web services) rather than ready-to-use applications. These services provide access to business assets such as data or functionality (e.g., payment or messaging service). Developers can use these APIs to build innovative applications like apps, internet platforms or B2B integrations in a relatively short period of time. One important component of an API Management platform is the developer portal; a social platform allowing developers to explore, use and learn APIs and to exchange ideas and solutions with other developers.
Examples such as Google, Twitter, Twilio (Telecommunication Services) and the Openbankproject show the power of APIs; currently other industries and companies are adopting the approach as well. In this talk, we present API Management main concepts, technologies and standards. Its use is illustrated on different case studies.

P3.2 Continuous Architecture Validation
Slides
Continuous Integration allows us to not only verify functionality of our code — it also allows us to verify that we adhere to architectural rules such as, “Do not call the same SQL statement 100 times per transaction”, “Do not transfer more than 50k per Web Service call”, or “The frontend must not access the database directly”. In this talk we discuss how you can leverage your existing test automation (Unit, Integration and Performance Tests) to also validate these architectural rules in your C/I. Validating these rules and letting violations of these rules fail your builds allow you to prevent typical architectural and performance problems to make it into test and production.

P4.1 Reference Architectures for Enterprise Big Data Use Cases
Slides
BigData technologies evolved from mostly unknown open source players to a broad range of applications, tools and methods.
In this talk we give an overview on the key pain points which lead to the development of this vast ecosystem, we state current and future requirements and illustrate lessons learned from practical client examples.
We finalize with a proposition of a BigData Reference Architecture and on how the data scientist’s workplace of the future has to look like based on the previously discussed use case scenarios.

P4.2 The Next-Generation BPM for a Big Data World: Intelligent Business Process Management Suites (iBPMS)
Slides
Business Process Management (BPM) is established, tools are stable, and many companies use it successfully. However, today’s business processes are based just on “dumb” data from relational databases or web services. Humans make decisions based on this information. Instead, the value of big data analytics should be integrated into business processes, too. Besides, user interfaces are inflexible. Modern concepts such as mobile devices or social media are not integrated into business processes. That is status quo. Companies miss a huge opportunity here!
This session explains the idea behind next-generation BPM, which includes big data analytics, social media, and mobile device support. The talk will focus on real world use cases. The audience will learn how to realize intelligent business processes technically by combining BPM, integration, big data and analytics.

P5 Methodical Improvement of Software Systems and Architectures: The aim42 approach
Slides
The presentation outlines AIM42, the architecture-improvement-method, a systematic yet pragmatic approach to improve productive systems. AIM42 relies on a small number of domain concepts and works in three phases (analysis, evaluation, improvement) supported by crosscutting activities. For each phase, AIM42 proposes a number of proven and established practices and patterns. The method addresses both business and technical stakeholders of software systems. aim is developed by an active community in open-source style, backed by extensive industrial experience and scientific research. It has proven to work under time- and budget constraints in various industries.
