Continuously Building a Book

Continuously Building a Book

I’m thrilled to announce the availability of a mini-book about Eclipse Vert.x. This book focuses on the development of reactive microservices in Java and covers reactive systems and reactive programming.

Writing a book, even for a mini-book is a tough task. While writing code and writing a book are very different experiences, you can apply the same process and good practice. I would like to list a couple of tips I’ve used to make the writing a bit easier.

Eclipse Vert.x Core Cheat Sheet

Eclipse Vert.x Core Cheat Sheet

Eclipse Vert.x is a toolkit used to build reactive and distributed systems on the Java Virtual Machine. Vert.x supports a variety of languages letting you choose which one you’d prefer. The Vert.x Core cheat sheet covers the creation of a project using Apache Maven, Gradle or the Vert.x CLI, and references most common Vert.x Core APIs, in 3 different languages (Java, JavaScript, and Groovy). Forgot how to create an HTTP server, use the HTTP client, implement a request-response on the event bus?  Just check the cheat sheet. Together with the Red Hat Developer Team, I’ve put together this handy cheat sheet – hopefully, you’ll find it useful too!

Red Hat Keynote Mobile App

This year’s middleware keynote address at Red Hat Summit talked about microservices, the power of the pipeline, and how developers and devops can work together to release code to production at a much higher rate.

The keynote also demonstrated how releases can be shipped so you can switch from the existing deployment to a new deployment (blue/green deployments), and demonstrated how to roll out a canary deployment to a subset of users to test out new features. (If the canary “dies”, roll the deployment back. If it lives, gradually ramp up the release of the deployment until all users receive the new code. )

To show all of this off, we needed to create something visual, where users could see the deployments change right in front of their eyes. That’s where the Red Hat Keynote Mobile Application came in.
