Ultimate Java Functional Projects

Unlock the Power of Java: From Fundamentals to Microservices Deployment.

Key Features

● Master Java fundamentals, OOP concepts, and build real-world projects.
● Develop and secure scalable microservices using Spring Boot and Docker.
● Deploy, monitor, and scale Java applications on AWS, Azure, and Kubernetes.

Book Description

Java remains the premier choice for building robust, scalable functional applications in enterprise environments. This book, Ultimate Java Functional Projects bridges the gap between theory and real-world application, equipping developers with the coding proficiency, architectural thinking, and deployment expertise essential for modern software engineering roles. It takes readers from core Java fundamentals through enterprise-grade microservices development, offering a strategic blend of theory, hands-on projects, and industry-aligned implementation.

Beginning with Java essentials—syntax, OOP principles, concurrency, and database integration—the book progressively advances into microservices architecture, API communication, centralized configuration, and fault tolerance. Each concept is immediately reinforced through practical projects, including a Weather App and Chat Application built with Spring Boot, enabling readers to apply learning directly to real-world scenarios.

The journey culminates with containerization using Docker, orchestration with Kubernetes, and deployment across leading cloud platforms (AWS, Azure, GCP). Hence, by the end of the book, developers will master the complete application lifecycle—from architecture and development to securing, deploying, and maintaining resilient, cloud-native Java solutions that meet today's enterprise standards.

What you will learn

● Master Java syntax, OOP principles, advanced libraries, and language features.
● Build RESTful services, and integrate databases using Spring Boot.
● Design and deploy microservices with service discovery and APIs.
● Implement encryption, authentication, and fault-tolerance mechanisms.
● Containerize Java apps with Docker and orchestrate them on Kubernetes.
● Deploy and scale microservices across AWS, Azure, and GCP platforms.

Who is this book for?

This book is exclusively tailored for Java Developers, Software Engineers, Backend Developers, Solution Architects, and DevOps Engineers aiming to master modern Java, microservices, and cloud deployment. Readers should have a basic understanding of Java programming and object-oriented concepts. A prior experience with Spring Boot, Docker, or Kubernetes would be helpful, but not compulsory.
