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.

Summary

We discussed a few deployment pitfalls in this chapter, beginning with the necessity of having a deployment plan, including rolling deployments, canary deployments, and other options, and ending with how Kubernetes deploys Pods. Outdated tools and technologies can also lead to failures; therefore, we should always upgrade and utilize the most up-to-date tools and technologies to avoid making mistakes. Team cooperation is also a significant aspect that influences deployments when it is not well defined. Later we discussed various DevOps practices and some factors to be considered, such as feature management, agile practices, the rollback strategy, approvals, and gates when implementing it. Finally, we learned about a few patterns, such as deployment stamps, deployment rings, and geodes, that we can use to cater to enterprise-scale workloads. With all of these patterns, you can use and adopt the right pattern based on the requirements and implement it to achieve the desired outcome...
