Proven Patterns for Designing Evolvable High-Quality APIs--For Any Domain, Technology, or PlatformAPIs enable breakthrough innovation and digital transformation in organizations and ecosystems of all kinds. To create user-friendly, reliable and well-performing APIs, architects, designers, and developers need expert design guidance. This practical guide cuts through the complexity of API conversations and their message contents, introducing comprehensive guidelines and heuristics for designing APIs sustainably and specifying them clearly, for whatever technologies or platforms you use.In Patterns for API Design: Simplifying Integration with Loosely Coupled Message Exchanges, five expert architects and developers cover the entire API lifecycle, from launching projects and establishing goals through defining requirements, elaborating designs, planning evolution, and creating useful documentation. They crystallize the collective knowledge of many practitioners into 44 API design patterns, consistently explained with context, pros and cons, conceptual solutions, and concrete examples. To make their pattern language accessible, they present a domain model, a running case study, decision narratives with pattern selection options and criteria, and walkthroughs of real-world projects applying the patterns in two different industries.Identify and overcome API design challenges with patternsSize your endpoint types and operations adequatelyDesign request and response messages and their representationsRefine your message design for qualityPlan to evolve your APIsDocument and communicate your API contractsCombine patterns to solve real-world problems and make the right tradeoffs"This book provides a healthy mix of theory and practice, containing numerous nuggets of deep advice but never losing the big picture . . . grounded in real-world experience and documented with academic rigor applied and practitioner community feedback incorporated. I am confident that [it] will serve the community well, today and tomorrow."--Prof. Dr. Dr. h. c.

In Continuous Architecture in Practice, three leading software architecture experts update the classic practices of the discipline for contemporary environments, software development contexts, and applications. Coverage includes: Discover what has changed, and how the role of the architect must change Reflect the quality attributes of today in evolvable architectures Understand team-based software architecture, and architecture as a GÇ£flow of decisionsGÇ¥ Architect for security, including continuous threat modeling and mitigation Explore architectural opportunities to improve performance in continuous delivery environments Architect for scalability, avoid common scalability pitfalls, and scale microservices and serverless environments Improve resilience and reliability in the face of inevitable failures Architect data for NoSQL, big data, and analytics Use architecture to promote innovation: case studies in AI/ML, chatbots, and blockchain

Some organizations are gaining immense business value from the cloud, just as promised but many are falling short. This book reveals why, and helps you get your tech stack and mindset right, so you can deliver software faster, better, at lower cost. Drawing on his experience as a pioneering CTO helping to revolutionize the insurance industry, Joseph Emison shows how to leverage "serverless" to change the gameand win it.Many serverless adopters are focusing on converting apps for AWS Lambda, but Emison's approach is more all-encompassing, and offers greater promise. Emison presents better ways to think about your tech stack, optimize build-or-buy decisions, choose the right vendor for each COTS or open-source solution, and draw on the industry's best managed services.Emison has written the definitive guide to leveraging "serverless" for maximum customer value. He reveals why "mindset" is so crucial to modern IT strategy, explains why and how to move towards a truly serverless mindset, and walks through the creation of a real-world serverless enterprise.Emison concludes with an exclusive directory of current managed services that enable the serverless mindset, with focused descriptions of each service, and concise explanations of its role in modern application architecture. Many of these offerings are unfamiliar to enterprise architectsbut they're working in production, and can radically simplify any serverless transition.

In a world of relentless change and accelerating uncertainty, organizations must continuously adapt and evolve to compete in environments they never anticipated. This requires upfront design for adaptability, and closer business alignment of software systems and team structures. To succeed, organizations must integrate advanced techniques from business strategy, software architecture, and team organization. Now, independent technology consultant Susanne Kaiser introduces a powerful unified toolset you can use to design, build, and evolve adaptive software systems and teams that are optimized for ever-faster rates of change.Kaiser shows how to combine Wardley Maps, Domain-Driven Design (DDD), and Team Topologies to understand your problem domain more clearly, focus on your crucial core subdomain, and reflect the dynamics of your business landscape. Using these tools, you'll learn how to design evolvable services within an adaptive system, which is in turn owned by a team organization that optimizes for fast flow.Kaiser goes beyond Domain Driven Design's popular patterns to reveal how DDDenables strategic design for long-term business success. Her accessible explanations and practical examples show how to combine DDD with intuitive Wardley Maps and powerful Team Topologies to improve success across the full lifecycle: strategy, design, implementation, deployment, operation, and evolution. As she demystifies and demonstrates these tools, Kaiser answers the most important questions faced by project participantsfrom CxOs to architects to software developers.
