Implementing Domain-Driven Design
Implementing Domain-Driven Design presents a top-down approach to understanding domain-driven design (DDD) in a way that fluently connects strategic patterns to fundamental tactical programming tools. Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.
Building on Eric Evans’ seminal book, Domain-Driven Design, Vaughn presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples—all applicable to C# developers—and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.
Vaughn Vernon, the author, takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.

Serverless as a Game Changer:
How to Get the Most Out of the Cloud
Leverage the serverless mindset to build and deploy software faster, better, and with less expense.
In this definitive guide, Joseph Emison shows how to leverage serverless for maximum customer value. He reveals why mindset is crucial to modern IT strategy and explains why and how to move toward a truly serverless mindset.
Many organizations are falling short when it comes to leveraging the cloud. Drawing on his experience as a pioneering CTO across multiple industries, Emison shows why and how you can gain immense business value from the cloud. While many serverless adopters focus on converting and building apps on serverless compute platforms like AWS Lambda, Emison offers better ways to think about your tech stack, optimize build-or-buy decisions, choose the right vendor for each commercial off-the-shelf (COTS) or open-source solution, and draw on the industry’s best managed services.
To help you develop a serverless mindset, Emison includes a case study demonstrating a real-world enterprise transition to serverless. The author also provides an exclusive directory of current managed services with focused descriptions and concise explanations of each service and its role in modern application architecture. Many of these services are unfamiliar to enterprise architects, but they are enterprise tested and can radically simplify any serverless transition.
- Evolve your tech stack and mindset to gain the full benefits of the cloud
- Deliver software faster, better, and at lower cost with serverless
- Use serverless architectures and managed services to offload tasks that don’t add value
- Follow a real-world case study taking you from where you are to where you want to be
- Explore an exclusive managed services directory to find resources to streamline your serverless transition

Adaptive Systems with Domain-Driven Design, Wardley Mapping, and Team Topologies
Architecture for Flow
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 DDD enables 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 participants–from CxOs to architects to software developers.
Balancing Coupling in Software Design
Successful Software Architecture in General and Distributed Systems
Microservices become immensely popular because it promised to help organizations build loosely-coupled systems that allow for fast, easy change. But microservices systems haven’t always kept that promise. This book identifies the deeper problem — how software architects and designers approach coupling – and introduces an important new approach for creating more successful designs whether you use microservices or not.
Instead of blindly avoiding coupling, leading software architecture expert Vladik (Vlad) Khononov proposes a novel method that transforms it into a powerful design tool: “balanced multi-dimensional coupling.” Khononov begins by surveying existing methods of evaluating coupling, and illuminating their strengths and limitations in the context of modern distributed systems. Next, he introduces a new multi-dimensional coupling model, and demonstrates how to harness it to build modular software.
Instead of focusing solely on a single approach, Balancing Coupling in Software Design illuminates underlying design principles that are ubiquitous in SOA, microservices, DDD, design patterns, and other paradigms, revealing how each of them can fail if thoughtful design principles for coupling are neglected — and how balanced coupling can make all of them work more effectively.
