| hands on microservices: Building Microservices Sam Newman, 2015-02-02 Annotation Over the past 10 years, distributed systems have become more fine-grained. From the large multi-million line long monolithic applications, we are now seeing the benefits of smaller self-contained services. Rather than heavy-weight, hard to change Service Oriented Architectures, we are now seeing systems consisting of collaborating microservices. Easier to change, deploy, and if required retire, organizations which are in the right position to take advantage of them are yielding significant benefits.

| hands on microservices: Microservices Eberhard Wolff, 2018-04-15 Microservices have many advantages: Efficiently implementing more features, bringing software into production faster, robustness and easy scalability are among them. But implementing a microservices architecture and selecting the necessary technologies are difficult challenges. This book shows microservices recipes that architects can customize and combine into a microservices menu. In this way, the implementation of microservices can be individually adapted to the requirements of the project. Eberhard Wolff introduces microservices, self-contained systems, micro- and macro-architecture and the migration to microservices. The second part shows the microservices recipes: Basic technologies such as Docker or PaaS, frontend integration with links, JavaScript or ESI (Edge Side Includes). This is followed by asynchronous microservices with Apache Kafka or REST / Atom. In the synchronous approaches, the book discusses REST with the Netflix stack, Consul, PaaS with Cloud Foundry, and Kubernetes. Finally, operations is discussed: Log Analysis with Elasticsearch and Kibana, Monitoring with Prometheus, and tracing with Zipkin. For each recipe there are suggestions for variations and combinations. Readers can experience all technologies hands-on with a demo project on GitHub. The outlook picks up on the operation of microservices and also shows how the reader can start with microservices in concrete terms. The book provides the technical tools to implement a microservices architecture. Demo projects and suggestions for self-study will complete the book. |

Also useful for developers in other languages like Java or C#.What You Will Learn- Identify where the microservice oriented architectures can tackle the most common problems in the software used by the big organisations.- Re-architecture an existing monolithic system into a microservices oriented software.- Build robust and scalable microservices using Seneca and Node.js.- Testing of the microservices in insolation in order to create a solid system.- Deploy and manage microservices using PM2- Monitoring the health of a microservice (CPU, memory, I/O...) and how the degradation of the performance in one microservice could degrade the performance of full system.In DetailMicroservices architecture is a style of software architecture. As the name suggests, microservicess refers to small services. For a large implementation, this means breaking the system into really small, independent services. Alternative to monolithic architecture (where the entire system is considered as a single big, interwoven segment), microservices approach is getting more and more popular with large, complex applications that have a very long lifecycle, which require changes at regular intervals. Microservices approach allows this type of changes with ease as only a part of the system undergoes changes and change control is easy.An example of such large system can be an online store-includes user interface, managing product catalog, processing orders, managing customer's account. In a microservices architecture each of these tasks will be divided and into smaller services. Also, these services will be further broken down into independent services-for user interface, there will be separate services for input, output, search bar management, and so on. Similarly, all other tasks can be divided in very small and simple services.Style and approachThis book is a comprehensive guide to developing production-ready implementation of the microservices architecture with Node.js. Each chapter builds up on the earlier one creating a strong foundation on which you create your own microservice in a distributed environment. |

| hands on microservices: Testing Microservices with Mountebank Brandon Byars, 2019-01-05 Even if you lab test each service in isolation, it's challenging, and potentially dangerous, to test a live microservices system that's changing and growing. Fortunately, you can use Mountebank to imitate the components of a distributed microservices application to give you a good approximation of the runtime conditions as you test individual services. Testing microservices with Mountebank introduces the powerful practice of service virtualization. In it, author Brandon Byars, Mountebank's creator, offers unique insights into microservices application design and state-of-the-art testing practices. You'll expand your understanding of microservices as you work with Mountebank's imposters, responses, behaviors, and programmability. By mastering the powerful testing techniques in this unique book, your microservices skills will deepen and your applications will improve.--Provided by publisher |

For those who are new to Enterprise Development using Spring Boot, you will be introduced to its core principles and main features thru a deep step-by-step tutorial on many components. For experts, this book offers some recipes that illustrate how to split monoliths and implement microservices and deploy them as containers to Kubernetes and OpenShift.The following are some of the key challenges that we will address in this book:- Introducing Spring Boot/Cloud for beginners- Splitting a monolith using the Domain Driven Design approach- Implementing the cloud & microservices patterns- Rethinking the deployment process- Introducing containerization, Docker, Kubernetes and OpenShiftBy the end of reading this book, you will have practical hands-on experience of building microservices using Spring Boot/Cloud and you will master deploying them as containers to Kubernetes and OpenShift. |
| hands on microservices: Practical Microservices Architectural Patterns Binildas Christudas, 2019 Take your distributed applications to the next level and see what the reference architectures associated with microservices can do for you. This book begins by showing you the distributed computing architecture landscape and provides an in-depth view of microservices architecture. Following this, you will work with CQRS, an essential pattern for microservices, and get a view of how distributed messaging works. Moving on, you will take a deep dive into Spring Boot and Spring Cloud. Coming back to CQRS, you will learn how event-driven microservices work with this pattern, using the Axon 2 framework. This takes you on to how transactions work with microservices followed by advanced architectures to address non-functional aspects such as high availability and scalability. In the concluding part of the book you develop your own microservices application using the Axon framework and true BASE transactions, while making it as secure as possible. You will: Shift from monolith architecture to microservices Build solid architectures without ACID-compliant databases Work with transactional systems Discover the high availability principles in microservices. |
