Making the Move – Design, Plan, and Execute

As web services get more and more complex, and software service companies grow in size, we require new ways of working to adapt and increase the speed of change, while setting a high quality standard. Microservices architecture has emerged as one of the best tools to control big software systems, enabled by new tools such as containers and orchestrators. We will start by presenting the differences between the traditional monolith architecture and the microservices architecture, as well as the advantages of moving to the latter. We will cover how to structure an architecture migration and how to plan to succeed in this difficult process.

In this book, we will deal with web server services, though some of the ideas can be used for other kinds of software applications, obviously by adapting them. The monolith/microservice architectures...

Develop a REST microservice in Python using the Flask framework and Postgres database

Description

Microservices architecture helps create complex systems with multiple, interconnected services that can be maintained by independent teams working in parallel. This book guides you on how to develop these complex systems with the help of containers. You’ll start by learning to design an efficient strategy for migrating a legacy monolithic system to microservices. You’ll build a RESTful microservice with Python and learn how to encapsulate the code for the services into a container using Docker. While developing the services, you’ll understand how to use tools such as GitHub and Travis CI to ensure continuous delivery (CD) and continuous integration (CI). As the systems become complex and grow in size, you’ll be introduced to Kubernetes and explore how to orchestrate a system of containers while managing multiple services. Next, you’ll configure Kubernetes clusters for production-ready environments and secure them for reliable deployments. In the concluding chapters, you’ll learn how to detect and debug critical problems with the help of logs and metrics. Finally, you’ll discover a variety of strategies for working with multiple teams dealing with different microservices for effective collaboration. By the end of this book, you’ll be able to build production-grade microservices as well as orchestrate a complex system of services using containers.

Who is this book for?

This book is for developers, engineers, or software architects who are trying to move away from traditional approaches for building complex multi-service systems by adopting microservices and containers. Although familiarity with Python programming is assumed, no prior knowledge of Docker is required.

What you will learn

Discover how to design, test, and operate scalable microservices

Coordinate and deploy different services using Kubernetes

Use Docker to construct scalable and manageable applications with microservices

Understand how to monitor a complete system to ensure early detection of problems

Become well versed with migrating from an existing monolithic system to a microservice one

Use load balancing to ensure seamless operation between the old monolith and the new service

I was trying to run the code for the second chapter and it seems like it doesn't work anymore as of 2023. I also looked at the Github repository for any updates provided with this book. This is a dependency issue I believe. I will check if Amazon can give me a refund or if the author can respond. I will change my review.

Disclaimer: The publisher reached out to me to review this book and has given me a review copy to do so. However, I promise to be 100% honest and completely forthcoming in my review of this book. In addition I am not obliged to review this book, I am simply doing so because I believed this book left enough of an impact for me to leave a review for it.Overview: This book is designed to teach people who have some knowledge of Software Design & Architecture but don’t have hands on experience with micro-services.While the book does say it is for those who know docker and python, I don’t think you need to be an expert at either to be able to understand the content of this book. The Docker stuff is explained very thoroughly and most of concepts you learn in this book can be applied to any language/framework.What I liked: I enjoyed how the book broke down micro-services and it’s uses. I felt that the diagrams as a whole were very well done and helped me understand the concepts. The programming examples were simple, yet real enough for you to connect the dots for a real world use case. I also enjoyed the fact that it went into the use of Docker containers for CI/CD. It’s an area that is generally avoided in books similar to this one, but it is an area that should be gone over more.What I didn’t like: Honestly, there wasn’t a lot that I didn’t like. While I said most diagrams were good, some diagrams were a bit small. In addition, I think it would be good to talk a little bit more about load balancing and also to dive a bit deeper about how to effectively scope a service.Final thoughts:This book does an excellent job introducing someone into Docker, Kubernetes, and Micro-services. Many of the concepts in this book will also pop-up during a System Design interview for larger tech companies, so it’s good preparation for those as well. This is a book I would highly recommend for anyone who wants to learn the basics and uses of Docker, Kubernetes, and Microservices.

Recomendo a leitura, livro bem completo abrangendo todo o ciclo do processo, com exemplos e referências complementares. Contribuiu de forma significativa para entendimento da transformação de monolíticos para microservicos.

Cooper Brevard Oct 16, 2020

The technologies and idioms presented here are compelling, but the prose is oftentimes confusing and the book suffers from a lack of diagrams (for example, when the process of introducing a load balancer is discussed). Those diagrams that are provided aren't particularly elucidating.

*Note: I served as a technical reviewer on this book*This book's title undersells whats inside. More than just an excellent technical guide to working with Microservices & Kubernetes, it provides a complete workflow and development philosophy to go with it. if you were setting up a development team for the first time, following the processes and guidelines in this book would give you an organization others will struggle to match. I highly recommend this book and it was a pleasure to review it.
