Solution Architecture Patterns for Enterprise

Gain a deeper understanding of how distributed systems work, as well as which applications and systems are used for specific business domains or industries. This book provides a set of solution architecture patterns that were developed based on the author’s experience building enterprise software systems for hundreds of different organizations across the globe. The architecture diagrams (patterns) and examples allow you to not only grasp the concepts, but to build working projects.

Solution Architecture Patterns for Enterprise starts with an introduction to the concepts of enterprise software systems and solution architecture and later moves to individual solution architecture patterns used in real-world enterprises. Subsequent sections cover various industry-specific solution architecture patterns that can be used to build domain-specific software systems. The book concludes with a view of what the future holds for solution architecture, including likely new developments in the field.

This book will help enterprise software architects and engineers to design and implement real-world enterprise software systems using best practices and techniques adopted by organizations across the globe. It provides software architecture blueprints to build domain-specific enterprise software systems. If you are working on any digital transformation project or initiative, you will find this book useful, as it provides quick reference on architecture and implementation to get started with your work.

WHAT YOU WILL LEARN

* Understand the key elements of enterprise software systems and how to design and implement them
* Master different approaches to build real-world software applications
* Build domain specific enterprise software systems
* Use open-source tools to build enterprise software systems

WHO THIS BOOK IS FOR

Software Developers, software architect, solution architects, and enterprise architects.

Chanaka Fernando has been working in the enterprise software domain for more than a decade designing, implementing, and supporting large-scale applications and systems across different industries including healthcare, financial services, education, and telecommunications to name a few. He is also the author of the book Designing Microservices Platforms with NATS, published in 2021. He has contributed to several open-source projects as a project lead, developer, and architect while working at WSO2, which is an open-source software company. Chanaka holds a bachelor’s degree from the University of Moratuwa, Sri Lanka in engineering, where he specialized in electronics and telecommunication engineering.

Chanaka started a GitHub project to share his experiences, and that repository has gained a lot of traction within the open-source community. That success has motivated him to write a book on the topic, going into greater detail with practical examples.
