Agile software development approaches have had significant impact on industrial software development practices. Today, agile software development has penetrated to most IT companies across the globe, with an intention to increase quality, productivity, and profitability. Comprehensive knowledge is needed to understand the architectural challenges involved in adopting and using agile approaches and industrial practices to deal with the development of large, architecturally challenging systems in an agile way. Agile Software Architecture focuses on gaps in the requirements of applying architecture-centric approaches and principles of agile software development and demystifies the agile architecture paradox. Readers will learn how agile and architectural cultures can co-exist and support each other according to the context. Moreover, this book will also provide useful leads for future research in architecture and agile to bridge such gaps by developing appropriate approaches that incorporate architecturally sound practices in agile methods. Presents a consolidated view of the state-of-art and state-of-practice as well as the newest research findings Identifies gaps in the requirements of applying architecture-centric approaches and principles of agile software development and demystifies the agile architecture paradox Explains whether or not and how agile and architectural cultures can co-exist and support each other depending upon the context Provides useful leads for future research in both architecture and agile to bridge such gaps by developing appropriate approaches, which incorporate architecturally sound practices in agile methods

Architecturally significant requirements (ASRs) drive and constrain many aspects of architecture. Eliciting and analyzing these requirements in the early phases of a project means that quality concerns can be discovered and addressed during the architectural design. This reduces the risk of costly and unnecessary refactoring. The challenge of emerging requirements is particularly evident in agile projects, which are inherently incremental; however, existing techniques for eliciting ASRs, such as win-win and i*, are typically rejected by agile development teams as being somewhat heavyweight. In this chapter, we present the notion of an architecturally savvy persona (ASP), which is used to emerge and analyze stakeholders’ quality concerns and to drive and validate the architectural design. ASPs are useful for discovering, analyzing, and managing ASRs, and designing and validating high-level architectural solutions that balance tradeoffs and satisfy stakeholders’ concerns. We show how ASPs can be used to discover quality concerns, drive architectural design, and preserve architectural qualities during long-term maintenance activities.

Running a dedicated instance of a software application can be burdensome to a customer if it involves a large amount of memory and processing overhead or a licensing fee or if the customer is a small company. Multitenancy (MT) architectures (MTAs) allow for multiple customers (i.e., tenants) to be consolidated into the same operational system, hence reducing the overhead via amortization over several customers. Lately, MTAs are drawing increasing attention because MT is regarded as an essential attribute of cloud computing and its new software delivery model, Software as a Service. In a moment of debate about the coexistence between architecture and agility, we introduce in this chapter a multitenancy, multitarget architecture (MT2A). MT2As are an evolution of traditional MTAs that reduce the various overhead by providing multiple services instead of a single service. In MT2As, there are new components added to the corresponding MTAs to manage the (now possibly) multiple services. MT2A is intended to support traditional agile development, as well as rapid deployment, by enabling the reuse of common components of the architecture. In this chapter, we also present an implementation of the architecture through an MT2 system called Globalgest.

More and more Agile projects are seeking architectural roots as they struggle with complexity and scale - and they're seeking lightweight ways to do it Still seeking? In this book the authors help you to find your own path Taking cues from Lean development, they can help steer your project toward practices with longstanding track records Up-front architecture? Sure. You can deliver an architecture as code that compiles and that concretely guides development without bogging it down in a mass of documents and guesses about the implementation Documentation? Even a whiteboard diagram, or a CRC card, is documentation: the goal isn't to avoid documentation, but to document just the right things in just the right amount Process? This all works within the frameworks of Scrum, XP, and other Agile approaches

We find surprisingly strong parallels in a playful comparison of the progression of thought in the architecture of the built world and its namesake in software. While some architectural progression in both fields owes to fashion, much more of it owes to learning—in both the field of design and collective human endeavor. We have been working on a paradigm called DCI (Data, Context, and Interaction) that places the human experiences of design and use of programs equally at center stage. It brings software design out of the technology-laced modern school of the 1980s into a postmodern era that places human experience at the center. DCI offers a vision of computers and people being mutually alive in the sense of Christopher Alexander’s great design. DCI opens a dialog contrasting metaphors of collective human reasoning and Kay’s vision of object computation, as well as a dialog between the schools of design in the built world and in software.

This chapter describes how to systematically prevent software architecture erosion by applying refactoring techniques. Software architecture modifications are common rather than the exception in software development. Modifications come in different flavors, such as redefining or adding requirements, changing infrastructure and technology, or causing changes by bugs and incorrect decisions. But no matter where these changes originate, they need special attention from software architects. Otherwise, if software architects merely focus on adding new features—(changes or extensions that by themselves might not be adequate), design erosion will be the final result. In a systematic approach, software architects evaluate the existing software design before adding new artifacts or changing existing ones. Whenever they identify architecture problems, they immediately resolve architectural issues, thus assuring high quality and sustainability. Software architecture refactoring enables such iterative architecture improvement. It consists of indentifying problems, applying the right refactorings, and testing the results. Architecture refactoring is often combined with code refactoring activities to add the best value. Refactoring patterns offer proven solutions for recurring architectural problems, hence providing a toolset to software engineers.

Large enterprise organizations are increasingly turning to the use of agile approaches for their information technology (IT) development and are encountering a range of challenges that were not faced by the early, usually smaller, agile adopters. Enterprise-scale organizations frequently have complex organizational structures and complex IT estates, including a mix of legacy and modern applications. Both of these attributes have a negative impact on the ease with which agile principles and practices can be applied. This chapter describes the experiences of Aviva UK during our early agile transformation journey. We describe the challenges that we faced, focusing particularly on those relating to our IT architecture, and we discuss the three architecture strategies that we put in place to drive success: These strategies have been developed based on both our own experience and the input and experience of agile consultants .We believe that they will be key drivers for success in any large corporate organization with an IT estate that includes both legacy and modern applications.

Organizations must adapt to survive, and their ability to change and innovate is driven by two key enablers - architecture and agile. Based on practical experiences of working with several clients adopting both architecture and agile practices, the author sheds light on those factors that resulted in successful transformations and the creation of a platform for innovation. The author concludes that architecture and agile practices are complementary and that their successful introduction within an organization is not just technical in nature, but also requires a focus on people and appropriate techniques for managing organizational change.

Utilize a new layers-based development model for embedded systems using Agile techniques for software architecture and management. Firmware is comprised of both hardware and software, but the applicability of Agile in embedded systems development is new. This book provides a step-by-step process showing how this is possible. The book details how the moving parts in embedded systems development affect one another and shows how to properly use both engineering tools and new tools and methods to reduce waste, rework, and product time-to-market. Software is seen not as a commodity but a conduit to facilitate valuable product knowledge flow across the company into the hands of the customer. Embedded Systems Architecture for Agile Development starts off by reviewing the Layers model used in other engineering disciplines, as well as its advantages and applicability to embedded systems development. It outlines development models from project-based methodologies (e.g., collaborative product development) to the newer modern development visions (e.g., Agile) in software and various tools and methods that can help with a Layers model implementation. The book covers requirement modeling for embedded systems (Hatley-Pirbhai Method) and how adapting the HP Method with the help of the tools discussed in this book can be seen as a practical example for a complete embedded system. What You’ll Learn Identify the major software parts involved in building a typical modern firmware Assign a layer to each software part so each layer can be separate from another and there won’t be interdependencies between them Systematically and logically create these layers based on the customer requirements Use Model-Based Design (MBD) to create an active system architecture that is more accepting of changes Who This Book Is For Firmware engineers; systems architects; hardware and software managers, developers, designers, and architects; program managers; project managers; Agile practitioners; and manufacturing engineers and managers. The secondary audience includes research engineers and managers, and engineering and manufacturing managers.

This is a practical guide for software developers, and different than other software architecture books. Here's why: It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face. It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties. It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts. It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail. It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.

Agile architecting is a key issue to scale agile to develop large software systems. This chapter describes a set of mechanisms that make agile architecting feasible. These mechanisms are smoothly integrated in a tailored Scrum for agile architecting by (1) defining product requirements in terms of features by using feature pools and feature trees to provide the portfolio and roadmap visions of a product, (2) designing highly flexible architecture called working architecture, (3) bridging user stories and software architecture through features and design decisions as traceability mechanisms, and (4) systematically assisting agile practitioners by conducting change impact analysis of features through various iterations of the agile process. This tailored Scrum for agile architecting has been successfully put into practice to develop several projects, which have been deployed in a software factory set up in collaboration between the Technical University of Madrid (UPM) and the company Indra. In this chapter, one of these projects is used to illustrate how this tailored Scrum has been applied and how it can be adopted.
