Evolve The Monolith To Microservices With Java And Node

Microservices is an architectural style in which large, complex software applications are composed of one or more smaller services. Each of these microservices focuses on completing one task that represents a small business capability. These microservices can be developed in any programming language. This IBM® Redbooks® publication shows how to break out a traditional Java EE application into separate microservices and provides a set of code projects that illustrate the various steps along the way. These code projects use the IBM WebSphere® Application Server Liberty, IBM API ConnectTM, IBM Bluemix®, and other Open Source Frameworks in the microservices ecosystem. The sample projects highlight the evolution of monoliths to microservices with Java and Node.

This book constitutes the proceedings of the Third International Symposium on Dependable Software Engineering: Theories, Tools, and Applications, SETTA 2018, held in Beijing, China, in September 2018. The 9 full papers presented together with 3 short papers were carefully reviewed and selected from 22 submissions. The purpose of SETTA is to provide an international forum for researchers and practitioners to share cutting-edge advancements and strengthen collaborations in the field of formal methods and its interoperability with software engineering for building reliable, safe, secure, and smart systems.

Building Microservices with Node.js will guide you through migration from a monolithic architecture to microservices. With this book, you’ll acquire a deep understanding of microservices architecture and apply it confidently in your web application projects. As you progress, you’ll be guided through the process of creating a simple application and incorporating the Node.js framework into it, along with its commonly used libraries. You’ll learn how the framework operates, how to configure it, and how to develop handlers for the web framework. Furthermore, you’ll explore how to deploy your application to a production server while going through the intricacies of JavaScript and Node.js. Later chapters will show you how to approach microservices in Node.js, implement them effectively, and integrate RESTful APIs. Additionally, you’ll gain insights into service-to-service authentication and authorization and learn how to work with databases and caching. To ensure a comprehensive understanding of the topic, you’ll get to grips with monitoring and logging in microservices with Node.js. By the end of this microservices book, you’ll be able to develop a web app using the Node.js framework, configure it, extend it using libraries available for this framework, and launch it using best practices.What you will learn Design domain-oriented microservices using domain-driven design (DDD) Understand collaboration techniques for inter-microservice communication and learn how to design an API gateway Automate microservice integration and deployment Split a monolith safely into microservices and understand how to test microservices effectively Use and implement microservices in Kubernetes and Docker environments Get to grips with best practices for maintaining microservices at scale Who this book is for This microservices and Node.js book is for backend developers, full-stack developers, software architects, and frontend developers who want to venture into the world of backend development and extend their capabilities. A fundamental understanding of the JavaScript ecosystem will be helpful but not necessary, as this book will cover the essentials of backend development, JavaScript programming, and Node.js.

It's not new to us that microservices are changing the way we conceive digital transformation, as organizations embrace digital transformation. Every day, more and more companies are betting on microservice adoption, and there is a strong reason for this: business needs to evolve and change at a fast pace, in order to adapt itself to satisfy a demanding 2.0 digital customer's experience in terms of overall service quality. Ensuring that such a change occurs seamlessly and progressively is one of the goals for microservices, and designing and building a solid microservice architecture is the way to guarantee that this happens from inception, by observing principles, best practices, design patterns, and reference models. This book provides a comprehensive walkthrough across the different concepts, frameworks, methodologies, and architecture building blocks that make up a microservice ecosystem and constitute a reference architecture from which you can get to multiple sub-architectures and implementations. Being an architect, you'll learn how to better design microservice-led and event-centric architectures in the right way from the early beginning, by showcasing learned lessons, best-practices do's, and don'ts. If you are starting your architecture career, it's the right place to get introduced to concepts and methodologies that you will then grow over time, as you acquire more experience. If you are a developer, but willing to jump into the exciting architecture world, this can also be good reading, however, be warned that some basic architectural understandings and concepts need to be first incorporated before walking through the advanced concepts presented throughout this book. This book requires you to have some minimal background around Docker and Microservices to better understand the more advanced concepts that are being explained.

How do you detangle a monolithic system and migrate it to a microservice architecture? How do you do it while maintaining business-as-usual? As a companion to Sam Newman’s extremely popular Building Microservices, this new book details a proven method for transitioning an existing monolithic system to a microservice architecture. With many illustrative examples, insightful migration patterns, and a bevy of practical advice to transition your monolith enterprise into a microservice operation, this practical guide covers multiple scenarios and strategies for a successful migration, from initial planning all the way through application and database decomposition. You’ll learn several tried and tested patterns and techniques that you can use as you migrate your existing architecture. Ideal for organizations looking to transition to microservices, rather than rebuild Helps companies determine whether to migrate, when to migrate, and where to begin Addresses communication, integration, and the migration of legacy systems Discusses multiple migration patterns and where they apply Provides database migration examples, along with synchronization strategies Explores application decomposition, including several architectural refactoring patterns Delves into details of database decomposition, including the impact of breaking referential and transactional integrity, new failure modes, and more

Microservices is an architectural style in which large, complex software applications are composed of one or more smaller services. Each of these microservices focuses on completing one task that represents a small business capability. These microservices can be developed in any programming language. They communicate with each other using language-neutral protocols, such as Representational State Transfer (REST), or messaging applications, such as IBM® MQ Light. This IBM Redbooks® publication gives a broad understanding of this increasingly popular architectural style, and provides some real-life examples of how you can develop applications using the microservices approach with IBM BluemixTM. The source code for all of these sample scenarios can be found on GitHub (https://github.com/). The book also presents some case studies from IBM products. We explain the architectural decisions made, our experiences, and lessons learned when redesigning these products using the microservices approach. Information technology (IT) professionals interested in learning about microservices and how to develop or redesign an application in Bluemix using microservices can benefit from this book.
