"Lagom Microservices Architecture Guide" The "Lagom Microservices Architecture Guide" is an authoritative and comprehensive resource for architects, developers, and technology leaders seeking to master the art of building scalable, resilient, and future-proof microservices systems using the Lagom framework. Beginning with an insightful exploration of the evolution from monolithic architectures to microservices, the book situates Lagom within the broader ecosystem of reactive and distributed frameworks, offering critical comparisons and highlighting core tenets rooted in simplicity, bounded context, and the principles of the Reactive Manifesto. Delving into practical methodology, the guide offers a wealth of expertise on service modeling, domain-driven design, event-first mindsets, and advanced API evolution. A significant emphasis is placed on event sourcing, CQRS, and state management, equipping readers with hands-on knowledge to implement robust, independently-deployable services. The book navigates the intricate landscape of inter-service communication—addressing synchronous, asynchronous, and streaming patterns—while providing actionable guidance on integration, security, fault tolerance, and operational excellence, including observability, automation, and scaling strategies for mission-critical deployments. Beyond technical implementation, this guide extends to organizational and strategic concerns such as migration from legacy systems, testing and quality assurance, regulatory compliance, and the governance required for large-scale distributed systems. It is forward-looking, offering guidance for cloud-native deployments, service mesh integration, and emerging trends in the reactive and event-driven microarchitecture space. Whether migrating an established application or designing a next-generation distributed platform, this book empowers professionals to harness Lagom’s capabilities for transformative success in the modern enterprise landscape.

What separates the traditional enterprise from the likes of Amazon, Netflix, and Etsy? Those companies have refined the art of cloud native development to maintain their competitive edge and stay well ahead of the competition. This practical guide shows Java/JVM developers how to build better software, faster, using Spring Boot, Spring Cloud, and Cloud Foundry. Many organizations have already waded into cloud computing, test-driven development, microservices, and continuous integration and delivery. Authors Josh Long and Kenny Bastani fully immerse you in the tools and methodologies that will help you transform your legacy application into one that is genuinely cloud native. In four sections, this book takes you through: The Basics: learn the motivations behind cloud native thinking; configure and test a Spring Boot application; and move your legacy application to the cloud Web Services: build HTTP and RESTful services with Spring; route requests in your distributed system; and build edge services closer to the data Data Integration: manage your data with Spring Data, and integrate distributed services with Spring’s support for event-driven, messaging-centric architectures Production: make your system observable; use service brokers to connect stateful services; and understand the big ideas behind continuous delivery

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. This book takes an holistic view of the things you need to be cognizant of in order to pull this off. It covers just enough understanding of technology, architecture, operations and organization to show you how to move towards finer-grained systems.
