Embracing Microservices Design

By: Ovais Mehboob Ahmed Khan, Nabil Siddiqui, Timothy Oleson

Overview of this book

Microservices have been widely adopted for designing distributed enterprise apps that are flexible, robust, and fine-grained into services that are independent of each other. There has been a paradigm shift where organizations are now either building new apps on microservices or transforming existing monolithic apps into microservices-based architecture. This book explores the importance of anti-patterns and the need to address flaws in them with alternative practices and patterns. You'll identify common mistakes caused by a lack of understanding when implementing microservices and cover topics such as organizational readiness to adopt microservices, domain-driven design, and resiliency and scalability of microservices. The book further demonstrates the anti-patterns involved in re-platforming brownfield apps and designing distributed data architecture. You’ll also focus on how to avoid communication and deployment pitfalls and understand cross-cutting concerns such as logging, monitoring, and security. Finally, you’ll explore testing pitfalls and establish a framework to address isolation, autonomy, and standardization. By the end of this book, you'll have understood critical mistakes to avoid while building microservices and the right practices to adopt early in the product life cycle to ensure the success of a microservices initiative.

Microservices are based on science

As we examine the definition of complex adaptive systems, we can see some similarities with many of the concepts of microservices, and even DDD. I challenge you to explore this topic of complex adaptive systems deeper as I believe this knowledge is the foundation of microservices, in my humble opinion.

A complex adaptive system is a dynamic network of system interactions, but the behavior of the whole system may not be predictable according to the behavior of the individual components or nodes. It is adaptive as the individual and collective behavior mutates and self-organizes, depending on the change event or collection of events.

Those systems have relationships with adjacent systems and can interact with each other and may fulfill some need for one another, which may be something that they cannot produce on their own. Understanding those relationships is as important as understanding an individual entity or node itself.

Some systems...
