Summary : 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

Summary : Verifying the security posture as a system evolves is indispensable for building deployable software systems. Traditional security testing lacks flexibility in (1) providing early feedback to the architect on the ability of the software to predict security threats so that changes are made before the system is built, (2) responding to changes in user and behavior requirements that could affect the security of software, and (3) offering real design fixes that do not merely hide the symptoms of the problem (i.e., patching). We motivate the need for an architecture-level testing for security grounded on incremental and continuous refinements to support agile principles. We use architecture as an artifact for initiating the testing process for security through subsequent and iterative refinements. We extend the use of implied scenario to reveal undesirable behavior caused by ambiguities in users’ requirements and we analyze detection their security implications. This approach demonstrates how architecture-centric evaluation and analysis can assist in securing systems developed using an agile development cycle. We apply this approach to a case study to evaluate the security of identity management architectures. We reflect on the effectiveness of this approach in detecting vulnerable behaviors and the cost-effectiveness of refining the architecture before vulnerabilities are built into the system.

Summary : 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

Summary : Architecture knowledge management (AKM) aims to codify and maintain the architectural knowledge of a software system in a form that can be easily accessed by different stakeholders. Integrating AKM with an agile project management paradigm is a challenge because the agile philosophy downplays both plan-driven development and documentation. Yet, by integrating lightweight AKM practices with the process, agile software development could avoid maintenance and communication problems arising from scarce documentation. In this chapter, we introduce existing technologies that could be used as elements of lightweight AKM for agile software development and present possible models to integrate AKM with Scrum, which is the most popular agile approach in use today. In particular, we advocate the exploitation of architectural evaluations to collect architecturally significant information semiautomatically and the use of automated document generation to expose the contents of an architectural information repository in an easily accessible form. The proposed models are based on observed architecting work practices in industry and on interviews carried out in industry to identify the architectural information flow in real-life agile projects.

Summary : A guide to successfully operating in a lean-agile organization for solutions architects and enterprise architects Key Features Develop the right combination of processes and technical excellence to address architectural challenges Explore a range of architectural techniques to modernize legacy systems Discover how to design and continuously improve well-architected sustainable software Book Description Many organizations have embraced Agile methodologies to transform their ability to rapidly respond to constantly changing customer demands. However, in this melee, many enterprises often neglect to invest in architects by presuming architecture is not an intrinsic element of Agile software development. Since the role of an architect is not pre-defined in Agile, many organizations struggle to position architects, often resulting in friction with other roles or a failure to provide a clear learning path for architects to be productive. This book guides architects and organizations through new Agile ways of incrementally developing the architecture for delivering an uninterrupted, continuous flow of values that meets customer needs. You'll explore various aspects of Agile architecture and how it differs from traditional architecture. The book later covers Agile architects' responsibilities and how architects can add significant value by positioning themselves appropriately in the Agile flow of work. Through examples, you'll also learn concepts such as architectural decision backlog,the last responsible moment, value delivery, architecting for change, DevOps, and evolutionary collaboration. By the end of this Agile book, you'll be able to operate as an architect in Agile development initiatives and successfully architect reliable software systems. What you will learn Acquire clarity on the duties of architects in Agile development Understand architectural styles such as domain-driven design and microservices Identify the pitfalls of traditional architecture and learn how to develop solutions Understand the principles of value and data-driven architecture Discover DevOps and continuous delivery from an architect's perspective Adopt Lean-Agile documentation and governance Develop a set of personal and interpersonal qualities Find out how to lead the transformation to achieve organization-wide agility Who this book is for This agile study guide is for architects currently working on agile development projects or aspiring to work on agile software delivery, irrespective of the methodology they are using.

Summary : 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.

Summary : The way in which architectural decisions are made changes when more agile development methods are used. This chapter focuses on architectural decisions and how they are made in industrial settings. From our literature research and experience, we have constructed three axes on which the architectural decision process of projects or companies can be projected. We evaluate this framework with five industrial case studies in which we have participated. In all of the cases, the differences between two points in time (phases) were evaluated. These differences helped us identify what aspects influence the efficiency of the project/company. The presented Triple-A Framework can be used in other projects to help locate places where the architectural process can be improved when the agility of a project changes.

Summary : 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.

Summary : 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.

Summary : 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.

Summary : 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.

Summary : 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.

Summary : 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.

Summary : “We need better approaches to understanding and managing software requirements, and Dean provides them in this book. He draws ideas from three very useful intellectual pools: classical management practices, Agile methods, and lean product development. By combining the strengths of these three approaches, he has produced something that works better than any one in isolation.” –From the Foreword by Don Reinertsen, President of Reinertsen & Associates; author of Managing the Design Factory; and leading expert on rapid product development Effective requirements discovery and analysis is a critical best practice for serious application development. Until now, however, requirements and Agile methods have rarely coexisted peacefully. For many enterprises considering Agile approaches, the absence of effective and scalable Agile requirements processes has been a showstopper for Agile adoption. In Agile Software Requirements, Dean Leffingwell shows exactly how to create effective requirements in Agile environments. Part I presents the “big picture” of Agile requirements in the enterprise, and describes an overall process model for Agile requirements at the project team, program, and portfolio levels Part II describes a simple and lightweight, yet comprehensive model that Agile project teams can use to manage requirements Part III shows how to develop Agile requirements for complex systems that require the cooperation of multiple teams Part IV guides enterprises in developing Agile requirements for ever-larger “systems of systems,” application suites, and product portfolios This book will help you leverage the benefits of Agile without sacrificing the value of effective requirements discovery and analysis. You’ll find proven solutions you can apply right now–whether you’re a software developer or tester, executive, project/program manager, architect, or team leader.
