This is the story of EagleEye, a monolithic enterprise application that had grown so large and fragile that every update felt like a daring rescue mission. Following the journey mapped out in Spring Microservices in Action, Second Edition
, let’s look at how this monolith was reborn into a resilient cloud-native system. Chapter 1: The Breakup (Core Development)
The story begins with the Licensing Service and the Organization Service. Instead of one giant codebase, the team broke EagleEye into small, self-contained units using Spring Boot. Each service became responsible for a single business task, communicating via REST and storing its own data in separate Postgres instances. Chapter 2: Lost and Found (Service Discovery)
In a world of dynamic containers, services couldn't have fixed addresses. The team introduced Service Discovery—the "phonebook" of the system. When the Licensing Service needed to verify an organization, it didn't look for a specific IP; it asked the discovery server to find a live instance of the Organization Service. Chapter 3: The Safety Net (Resiliency)
Then came the inevitable: a network glitch. In the old days, one failing service would cause a domino effect, crashing the entire app. By applying Resiliency Patterns with Resilience4j, the team built "circuit breakers". If the Organization Service slowed down, the Licensing Service simply tripped the circuit, preventing a total system collapse. Chapter 4: The Front Door (API Gateway)
To handle the chaos of multiple public entry points, they built the Spring Cloud Gateway. Every request now passed through this single "front door," where security, logging, and routing policies were applied before any traffic reached the inner services. Chapter 5: Silence and Whispers (Event-Driven Design)
For tasks that didn't need an immediate answer, the team moved away from talking directly. They used Spring Cloud Stream and Kafka to let services "whisper" events to each other. If a license was updated, an event was published; any service interested in that change could react in its own time without blocking the user. Chapter 6: The Watchtower (Observability)
Finally, they stopped flying blind. By implementing Distributed Tracing with Zipkin and Sleuth, every request was given a unique ID. The team could now watch a single user click travel across five different services on a dashboard, pinpointing exactly where a delay occurred.

Spring Microservices in Action: Second Edition - Audiobook by John Carnell, Illary Huaylupo Sànchez
Let’s be real. You’re a developer, not the FBI. Maybe you’re in a country with weak copyright enforcement, or you’re a student with no budget. You might still click that raw GitHub link.
If you absolutely insist on evaluating a suspicious PDF from GitHub (for educational purposes only – and I do not endorse piracy), here’s how to do it safely: But Wait – What About That “Free GitHub PDF” I Found
.pdf, not .exe, .scr, .js, or .vbs.Even then, remember: the authors spent hundreds of hours writing that book. If you use their knowledge to earn a salary, consider buying a copy as a professional courtesy.
Copyright infringement is no joke. Manning Publications actively files DMCA takedown requests. While individual downloaders are rarely sued, the person who uploaded the file can face legal action, and your GitHub account could be flagged if you repost.
If you’ve landed on this page, you’re likely a Java developer searching for a free PDF copy of Spring Microservices in Action, Second Edition hosted on GitHub. You probably typed the exact phrase: "spring microservices in action 2nd edition pdf github" into your search bar.
Let’s address the elephant in the room immediately: Yes, you will find multiple GitHub repositories claiming to host this PDF. No, most of them are not legal, and downloading them comes with significant risks.
But before you click that link, let’s break down what this book offers, why it’s still relevant in 2025, the legal and security dangers of grabbing a “free” GitHub PDF, and the legitimate ways to access the content (including legal open-source alternatives on GitHub).
Manning offers a subscription service where you can read the book online and download the code. If you only need a chapter or two, this is cost-effective.
Once purchased, clone the official GitHub repo:
git clone https://github.com/ihuaylupo/spring-microservices-in-action-2nd.git
This is where the search keyword becomes interesting. Spring Microservices in Action, 2nd Edition has a formal, official GitHub repository. The authors provide the complete source code for every chapter on GitHub.
The official repository is: github.com/ihuaylupo/spring-microservices-in-action-2nd
In this repository, you will find:
Because the book encourages you to clone this repository and run the code yourself, it is entirely legitimate to search for the book’s GitHub repo. The confusion arises when people hope that the official repo also contains a PDF of the book—which it does not.
