Here we go again for a new post 😁 After publishing my Quarkus book last September, I got many requests about creating reactive applications with the Quarkus Framework. Today, I will show you how to make a Reactive CRUD Application with the Quarkus Framework and backed by a PostgreSQL Database. Building our the Reactive Quarkus Application The full source code is available on my Github. We will generate our project using the code.quarkus.io. Our application will need 8 extensions from the portal: ...

Today is the big day 🥳🥳 My third book “Playing with Java Microservices with Quarkus and Kubernetes” is available in Early Access 🎉🎊🎈✨ Book cover I started working on the book starting from June 😁 I spent nearly 5 months presenting the most interesting and powerful features of the Quarkus Framework. When I started the Proof-of-concept, I didn’t have the idea of writing a book on Quarkus, I was just discovering. I found myself spending more and more time reading the documentation, trying some features and extensions, and then I got the idea to write the Quarkus version of my “Playing with Java Microservices” Book 😁 ...

Today, I will not be sharing a tutorial or a review, I will share with you my new book news ! 🥳 I just finished typing the fourth chapter. These four chapters belong to the first part of the story: the MoNoLITHiC dedicated part 🤪 .. What’s new ? In my previous book “Playing with Java Microservices on Kubernetes and OpenShift” there was a Docker-only chapter in the middle of the book. Now, in the book, there is no Docker-only chapter, there is a Chapter Zero dedicated for Containerization, with Docker and alternatives ! 😄 ...

The workshop “Playing with Java Microservices on Kubernetes” was held from 02/01 to 04/01 - 2020, at the National School of Computer Sciences, in Manouba, Tunisia. Great gift 😍 The workshop was done on 21 Hours of training about Java, Spring Boot, DDD, Docker, Kubernetes, Cloud Patterns, Azure AKS & Functions… Some Github repositories used in the sessions: Monolith Example Microservices Examples Speaker Deck The event was sponsored by Microsoft 😍🤩🥳 !! ...

In one of the previous posts, I introduced the Azure Functions Java. I felt that I need to write a dedicated tutorial to this great Azure Serverless service 😁 In this post, I will be covering many concepts in deep: Triggers and bindings Events and messaging Deployments & Consumptions Monitoring Generating the hello-world project We will scaffold a Java-based Azure Function project using Maven Archetypes, using this command: 1 2 3 4 5 6 7 8 9 $ mvn archetype:generate -DarchetypeGroupId=com.microsoft.azure \ -DarchetypeArtifactId=azure-functions-archetype \ -DappName=hello-world-app-example \ -DappRegion=FranceCentral \ -DresourceGroup=helloworld-rg \ -DgroupId=com.helloworld.group \ -DartifactId=helloworld-functions \ -Dpackage=com.helloworld \ -DinteractiveMode=false The generated project will look like: ...

January 2018, Red Hat acquired CoreOS for 250 million dollars 🤩. CoreOS was one of the leading companies of Linux & Containers market with their wide offer of products: CoreOS Tectonic: container application platform based on Kubernetes. CoreOS Container Linux: lightweight Linux distribution designed to run containerized applications. CoreOS Operators Framework: an open source toolkit designed to manage Kubernetes native applications. CoreOS Quay: a container registry for building, storing, and distributing your private containers. CoreOS rkt: an application container engine developed for modern production cloud-native environments. even more and more.. Red HatOpenShift 3.x was facing many big problems especially in installations and upgrades. It was a real nightmare to install an OCP Cluster. I never heard an OCP Admin talking about upgrading OCP without discussing the problems that they faced. Personally, I worked for two customers from 2017 to 2019 that adopted OCP, and when it comes to cluster upgrades they were dedicating time and they were bringing people from Red Hat to help them do that 😂 Although, the upgrades were guaranteed by Red Hat in all technical and commercial announcements. ...

Before the introduction This is my first tutorial about one of the Microsoft’s tools and platforms.. I started working for Microsoft on May 6th, I started to look to this huge and mysterious world by the eyes of a Java Developer. I will try to make some tutorials based on the great tools that I use or discover in the Microsoft ecosystem 😊 ⚠️ Disclaimer : This is not a marketing content 😆 I just want to share with you a feedback about tooling to boost your productivity and to make the Java journey wonderful 😍 ...
