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: ...

Quarkus is one of the current trends of the Java ecosystem. I’m already in love with it. I’m using it along with Spring Boot, and when I choose, I choose Quarkus. 😁 This week, I was working on a Batch POC using Azure Functions and Azure Automation. So I thought it will be useful to share the exercise with you. 😁 What I want to do? I will be taking a small use case: I need a batch that will be invoked at some specific time or manually, checking all the available VMs and starting or shutting down all those that we choose. ...

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 ! 😄 ...

Reactive programming ! Wow ! What a fancy buzzy word ! I waited so much to write a blog post about this trend 😃 I was waiting for the landscape to be mature to made a one-shot tutorial 😁 Today, I will show you how to make a Reactive Spring Boot application, with a Reactive CRUDs using Spring Data Reactive Relational Database Connectivity (R2DBC) with PostgreSQL and for sure the famous Webflux. Don’t be scared if you don’t know any of these topics. We will be introducing all of them smoothly ! 😊 ...

In an enterprise level, it’s obvious for applications to be based on messaging for communication. This is done using a middleware between these applications as a Message Bus that enables them to work together. One of the most used Messaging solutions is Apache Kafka: Kafka is an open-source stream-processing software platform developed by LinkedIn and donated to the Apache Software Foundation, written in Scala and Java. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds. It is horizontally scalable, fault-tolerant, wicked fast, and runs in production in thousands of companies. Kafka Clusters can be deployed in bare metal or in the Cloud. ...

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 😍🤩🥳 !! ...
