Hands-On Microservices with Node.Js


Book Description

Learn essential microservices concepts while developing scalable applications with Express, Docker, Kubernetes, and Docker Swarm using Node 10 Key Features Write clean and maintainable code with JavaScript for better microservices development Dive into the Node.js ecosystem and build scalable microservices with Seneca, Hydra, and Express.js Develop smart, efficient, and fast enterprise-grade microservices implementation Book Description Microservices enable us to develop software in small pieces that work together but can be developed separately; this is one reason why enterprises have started embracing them. For the past few years, Node.js has emerged as a strong candidate for developing microservices because of its ability to increase your productivity and the performance of your applications. Hands-On Microservices with Node.js is an end-to-end guide on how to dismantle your monolithic application and embrace the microservice architecture - right from architecting your services and modeling them to integrating them into your application. We'll develop and deploy these microservices using Docker. Scalability is an important factor to consider when adding more functionality to your application, and so we delve into various solutions, such as Docker Swarm and Kubernetes, to scale our microservices. Testing and deploying these services while scaling is a real challenge; we'll overcome this challenge by setting up deployment pipelines that break up application build processes in several stages. Later on, we'll take a look at serverless architecture for our microservices and its benefits against traditional architecture. Finally, we share best practices and several design patterns for creating efficient microservices. What you will learn Learn microservice concepts Explore different service architectures, such as Hydra and Seneca Understand how to use containers and the process of testing Use Docker and Swarm for continuous deployment and scaling Learn how to geographically spread your microservices Deploy a cloud-native microservice to an online provider Keep your microservice independent of online providers Who this book is for This book is for JavaScript developers seeking to utilize their skills to build microservices and move away from the monolithic architecture. Prior knowledge of Node.js is assumed.




Developing Microservices with Node.Js


Book Description

Learn to develop efficient and scalable microservices for server-side programming in Node.js using this hands-on guideAbout This Book- Real world example explained chapter after chapter with code examples.- Useful concepts for other languages like Java or PHP- Easy to follow by people with little to none experience in Node.js- Node.js Version 0.12.2 and the latest compatible versions of Seneca and PM2Who This Book Is ForNode.js developer with basic server-side development knowledge - but no knowledge of implementing microservices in Node.js applications. 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.

Practical Microservices


Book Description

MVC and CRUD make software easier to write, but harder to change. Microservice-based architectures can help even the smallest of projects remain agile in the long term, but most tutorials meander in theory or completely miss the point of what it means to be microservice-based. Roll up your sleeves with real projects and learn the most important concepts of evented architectures. You'll have your own deployable, testable project and a direction for where to go next. Much ink has been spilled on the topic of microservices, but all of this writing fails to accurately identity what makes a system a monolith, define what microservices are, or give complete, practical examples, so you're probably left thinking they have nothing to offer you. You don't have to be at Google or Facebook scale to benefit from a microservice-based architecture. Microservices will keep even small and medium teams productive by keeping the pieces of your system focused and decoupled. Discover the basics of message-based architectures, render the same state in different shapes to fit the task at hand, and learn what it is that makes something a monolith (it has nothing to do with how many machines you deploy to). Conserve resources by performing background jobs with microservices. Deploy specialized microservices for registration, authentication, payment processing, e-mail, and more. Tune your services by defining appropriate service boundaries. Deploy your services effectively for continuous integration. Master debugging techniques that work across different services. You'll finish with a deployable system and skills you can apply to your current project. Add the responsiveness and flexibility of microservices to your project, no matter what the size or complexity. What You Need: While the principles of this book transcend programming language, the code examples are in Node.js because JavaScript, for better or worse, is widely read. You'll use PostgreSQL for data storage, so familiarity with it is a plus. The books does provide Docker images to make working with PostgreSQL a bit easier, but extensive Docker knowledge is not required.
