Book Description :

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

Book Description :

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.

Book Description :

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. You will also find this book useful if you're a senior developer or a budding architect looking to understand an agile architect's role by embracing agile architecture strategies and a lean-agile mindset. To understand the concepts covered in this book easily, you need to have prior knowledge of basic agile development practices.

Book Description :

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.

Book Description :

This chapter discusses software architecture analysis in the context of agile processes. Agile processes are characterized by incremental and interleaved activities and by a focus on continuous improvement and delivery. Most approaches to software architecture analysis, however, have been developed to be performed at dedicated points in the development process or as external evaluation activities and not as continuous activities throughout the development process. This chapter discusses continuous software architecture analysis (CSAA). It reviews important requirements for CSAA and outlines how CSAA is supported by current software architecture analysis approaches. It further presents experiences with an approach for continuous structural and conformance analysis and identifies future research challenges.

Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

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.

Book Description :

The award-winning and highly influential Software Architecture in Practice, Third Edition, has been substantially revised to reflect the latest developments in the field. In a real-world setting, the book once again introduces the concepts and best practices of software architecture—how a software system is structured and how that system’s elements are meant to interact. Distinct from the details of implementation, algorithm, and data representation, an architecture holds the key to achieving system quality, is a reusable asset that can be applied to subsequent systems, and is crucial to a software organization’s business strategy. The authors have structured this edition around the concept of architecture influence cycles. Each cycle shows how architecture influences, and is influenced by, a particular context in which architecture plays a critical role. Contexts include technical environment, the life cycle of a project, an organization’s business profile, and the architect’s professional practices. The authors also have greatly expanded their treatment of quality attributes, which remain central to their architecture philosophy—with an entire chapter devoted to each attribute—and broadened their treatment of architectural patterns. If you design, develop, or manage large software systems (or plan to do so), you will find this book to be a valuable resource for getting up to speed on the state of the art. Totally new material covers Contexts of software architecture: technical, project, business, and professional Architecture competence: what this means both for individuals and organizations The origins of business goals and how this affects architecture Architecturally significant requirements, and how to determine them Architecture in the life cycle, including generate-and-test as a design philosophy; architecture conformance during implementation; architecture and testing; and architecture and agile development Architecture and current technologies, such as the cloud, social networks, and end-user devices

Book Description :

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.
