Description

“Ninety-five percent of the words are spent extolling the benefits of ‘modularity’ and that little, if anything, is said about how to achieve it.”—Glenford J. Myers

The above quote is 40 years old. Today, nothing has changed except terminology. Time to fix this.

Vladik Khononov breaks down how to decompose a system into loosely coupled components, how to draw boundaries between services, how to decide whether some logic belongs to one service or another, and how domain-driven design (DDD) can help you make those decisions. And he takes a stab at answering the age-old question of what part of a microservice should be “micro” and how it can be measured.

You won’t hear about Docker or Kubernetes. Actually, nothing related to infrastructure. Instead, you’ll dive into the difference between microservices and bounded contexts, discover when each pattern should be used, and get takeaways from Vladik’s experience optimizing microservices-based architectures at NaXex.

Prerequisite knowledge

Experience with DDD and microservices (useful but not required)

What you'll learn

Learn what microservices are, bounded contexts, and the differences between them
Identify heuristics for applying each pattern when designing distributed systems

Vladik (Vlad) Khononov is a software engineer with over 15 years of industry experience at companies large and small in roles ranging from webmaster to chief architect. A longtime proponent of domain-driven design and evolutionary architecture, Vlad helps companies make sense of their business domains, untangle monoliths, and tackle complex architectural challenges. He maintains an active media career as a public speaker and blogger and has spoken at numerous industry conferences—including O’Reilly Software Architecture, Domain-Driven Design Europe, and NDC Conference—about subjects such as domain-driven design, microservices, and software architecture in general. In addition to his media work, he co-organizes the Domain-Driven Design Israel and Tel Aviv Software Architecture meetup groups. He lives in northern Israel with his wife and an almost-reasonable number of cats.
