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.

Service meshes

A service mesh provides an abstraction layer on top of microservices to facilitate inter-process communication. The idea behind a service mesh is to decouple communication concerns from the implementation of microservices and handle them in a consistent manner across the microservices architecture. The following diagram depicts a simple service mesh architecture for microservices:

Figure 6.14 – A service mesh

The service mesh is a configurable communication infrastructure layer that guarantees the reliable delivery of requests across a complex topology of services. This enables teams to focus on business capabilities and leave the communication concerns to the service mesh. The service mesh is composed of two components: the control plane the and data plane. The data plane is implemented as a sidecar proxy that's responsible for intercepting data packets across the network and performing various functions before forwarding. The data...
